Rich I think you are dead on in regards to temp. The more you allow your tank to fluctuate the more resistant to extremes it will be. My reef normally swings between 79.5 and 83 with the occasional 85 on a really hot day. Yesterday it was almost 100 where I live and I forgot to turn the air conditioner on when i left. I got home at 8pm to find my tank was 88.4. To my amazement all SPS, LPS, zoas, rics, and fish where perfectly fine.
Here are a few more myths: 1. Nano tanks will have unstable salinity compared to larger tanks. The rate salinity changes is controlled by 3 things. The amount of surface area in relation to the volume of the system. Temperature and air flow over the waters surface. In many cases a very large tank will be less stable then a very small one. (I think the same is true for many other things in a nano, but I'm not trying to write a novel here.) 2. I often hear people say that they are just going to add a shrimp to their overstocked tank because they are already at the limit of fish. Hate to break it to you, but shrimp eat and poop too.

I'm not sure if these are misconceptions; they sound to me more like guidelines with a few caveats.
Anyway, good read.

Ok, after reading what I missed since yesterday, I have one:
Misconception: cause and effect relationships created by casual observation by the average/experienced hobbyist is hardly fact and IMO hardly - if at all - usable as evidence. Example: I started dosing garlic and ich went away; garlic is a cure to ich (simply an example, nothing i stand by) Anyone see the problem? There are so many variables unaccounted for that are simply not observed and/or recorded by the average hobbyist. A lot of these corrected "misconceptions" seem to be a product of these cause & effect relationships so definitively established by the author. I'm not specifically criticizing anyone but IME this type of information comes and goes over time and hardly holds any ground in the long run. There is a lot of good (and seemingly controversial) information in this thread, it's just impossible to sift through who is right and wrong. Everyone seems to have an expert opinion on everything. It seems the old adage "What works for you may not work for me" applies here - in some cases.

17ish.) You should test for nitrites regularly since they are toxic to saltwater aquarium inhabitants.
Nitrites will only cause apparent stress in most saltwater fish and invertebrates at VERY high levels. Some marine fish and invertebrates have shown to be tolerant of nitrite well in excess of 1000ppm. Conclusion: After the initial nitrogen cycle is complete there is little to no reason to ever test for nitrites again in a marine aquarium. |

thanks for the post---if the "certain" benifit is that they will enhance water quality can't you get the same result with running carbon in a phosban reactor(a lot cheaper too)

I don't really have an opinion on the use of garlic (or experience for that matter) I was just using it as a simple example. I'm sure somebody knows though.

I don't expect people accept what I and others are saying in this thread as gosphel. However, at least very least hopefully it will cause some people to take a step back and question why they're doing things the way they are. Also, hopefully it will make some people stop recycling incorrect information over and over again. Last edited by Peter Eichler; 08/20/2007 at 09:08 PM. |

The temp thing is what has really been sticking out to me... I have never tried to regulate my temp (don't even have a heater) BUT I don't think it's a safe assumption to say that just because you at some point stopped regulating your temperature at some point everything looked healthier. I neither agree nor disagree about temp regulation causing harm but I don't think that it being casually observed by a handful of hobbyists makes it fact - or guideline for that matter. I obviously don't care about regulation - however - for the purpose of algae control alone I would like to see my temps as low as possible. Anyway, I am extremely skeptical when it comes to advice or secondhand information. Healthy skeptical - not conspiracy theory skeptical I am very reluctant to repeat information that I'm not positive about. And don't get me wrong I haven't dismissed any thoughts or ideas from this thread (well, maybe 1 or 2), but I am wary about it.

HBtank---don't know about the super-saturated kalk bit: but I dropped about a gallon of kalk bottom slurry into my 54 [80 total gallons] with less problem than I did when I dumped about 5 g of fresh ro/di into a 54 with 64 total gallons...but I can agree with you, that topoff disasters are in general among the worst and most common disasters among those just starting with saltwater tanks.
Since I finally got all my topoff-related switches on one power strip with an easy 'off' button my life has been much calmer. I've now systematized water changes with the mantra "first cut off the ATO and THEN draw water from your tank...." I also use a kalk reactor, which makes consistent concentration of the kalkwasser easier.

Thanks to the mods for correcting my Bitburger induced spelling of misconception! I'd also like to thank Bitburger for giving me the the inspiration to create this thread. In fact I think I may have found the reason for German superiority in aquarium keeping for so many years. Drink Bitburger and you can have a reef aquarium that looks like this in no time!

All temp fluctuation arguments and kalk arguments aside there is one that was brought up (somewhat) in here that I have been experimenting with myself here. The idea that U.V. sterilizers will kill "pods" along with the needlewheel emaciating them.
I've been a bit too attached to harpacticoid copepods lately (or so my friends and neighbors think) and one of the nifty things I have done to experiment is to run a culture through UV as well as an impeller pump. I will tell you this from MY personal experience (once again, I am a "garage" expert at most, and thus... not an expert at all...) Needlewheels DO shred copepods in the copepodite (adult) stages but many in the naupliar stages will still make it through. I've been trying to come up with a tide pool simulation and have been playing with several ideas with the fear that a pump will tear these guys apart and have found through examination of population in 5ml samples that impeller pumps with larger impellers do not affect population at all. This would make sense as the impeller blades are flat and have a tendancy to push water with very little "cutting" through the tension like a needle wheel would. As far as U.V. goes, as stated before will need a very slow flow rate and high exposure to be effective against a lot of the items found in our reef tanks. I used a current gamma 8 watt UV unit inline with a maxijet 1200 on one of my cultures as a test with no measurable population loss, in fact this culture seems to have grown faster (most likely due to flow related causes and NOT the UV sterilizer). While I'm still playing with these features, I must debunk the "pumps kill your pods" misconception as impeller pumps have had no effect on several of my cultures. The U.V. myths are still yet to be fully explored but without prolonged exposure I fail to see how larger sized organisms like copepods and amphipods can truly be affected, what drives this nail even deeper is that in order to cycle a tanks contents through a U.V. Sterilizer at a low enough flow rate but large enough capacity to erradicate parasites and bacteria effectively it would require one hell of a large unit. Awesome thread BTW

Some good things happened as a result of the Jaubert method though. Deep sandbeds sprung up from there, which if nothing else made many people realize they have other options besides a bare bottom tank. The use of algae as nutrient export became more common. This is pure speculation on my part but I can't help but think that pumps such as the Turbelle were inspired by some of the beliefs which Jaubert held about plankton populations and conventional pumps. I'm probably forgetting a few as well... Sorry for the quick/incomplete history lesson |

Perhaps someday I'll have a "breakthrough" finding with my copepod cultures, I must say it's one of the reasons why even now I sit here in my garage examining worms that have invaded one of my cultures under a cheap garage sale microscope. But I dont think I will ever be able to claim that I am an expert... as I have way too much to learn about everything. (This is one of the reasons why I like this thread in particular). On the subject of turbelles and worm drive pumps, since I am working on this tide pool simulation it is one of the things I had never considered and it might just be the answer to what I am trying to acheive. I must point out that even out of context thoughts and comments often lead to great ideas in the context of a field of study. Since we're all in the process of debunking myths, I must ask..... has anyone studied amphipods at length enough here to say whether or not they really impact copepod populations through ingestion? (laymans terms, do they eat them all up?).

I'm not sure if what you're asking for exists, but if it does you'll probably find it here.

there has been new technology that has made keeping a reef tank less problematic and more affordable for a huge amount of hobbyists the internet has made referencing and linking to information and scientests alot easier. the internet has allowed the sharing of experiences between hobbyists and scientests. There has been a successful period of time that has allowed "experience' to be blended with "knowledge" and new concepts tried out. Sites like this one allow the presentation of alot of points of view and discussion-----and this is how misconceptions are best dealt with.

The gain is immense though and cannot be discounted, not only does the vast majority of average humanity (non researchers, etc) have freeley available access to a plethora of information, we now have a constantly available real time channel where we can share and explore our own personal findings. Thus increasing the speed and area that research covers at lower monetary costs but higher time costs (sorting the information out). It's a means of collaboration, and yes in any collaborative effort there is always good info and bad, and there is always a ton of grey area. But without collaboration we will never sort out the three areas and final answers would become a crapshoot at best! just my 2 cents

Gone are the days when one reads the symptoms of prostrate cancer on the net and rush to their doctor demanding the 'plastic glove" People learn quickly( and we are teaching them) how to evaluate sites, information etc on the net. This kind of site makes it very easy to check out the experience they have had, what they have had experience in, and who are their supporters. situation here: I have been chemistry/biology/math/It teacher for 37 years, have 1200 posts in four months, and have one years experince in reef tanks. Now Greenbean--(for example--it could have been Bertonli, boomer etc etc ) has had 7,000 posts, many years experince , get many different tanks and is a marine biologist) Whose answers are you really going to put faith in. Equally, this site provides an excellent communication vehichle where all can discuss their small experinces with experts like we have. any I can't begin to tell you what I have learned today rather then in the past(the old days when the phone was on the wall instead in your pocket) IMHO for sure Scott
