nice thread, good to see people building their own tank furniture.
do they have ikea's in canada? your kitchen/living room looks almost right out of a catalog... love the rug. |

Here are a couple more pics of the stand in progress.
This one shows me measuring for the cutting board (starboard) bottom. This pic shows the blue cutting board installed. And this one shows a close up of the board. |

Just finished reading the thread. Looks like a well-planned setup. I had to chuckle to myself reading the comments about Mitch lying and all. Seems like everyone has the same story about him. However, if I got a glass tank I would get it from him too. Just too good of a deal to pass up.
How warm does your Hammerhead run? How did you figure out the calculations to know the Hammerhead can effectively run that many eductors? I know you are running 2 returns but have you considered running a second closed loop? The closed loop will be providing a large majority of the flow for your inhabitants. What happens if something goes wrong with the pump? I always like to have a back-up plan for redundancy. Of course you can always have an extra pump on hand to replace the CL if something happens. However, then you have to consider if you were on vacation when the CL pump goes down and you aren't home to swap out the pumps. I noticed in one of your earlier posts that you broke the volute on your Hammerhead. The same thing happened to me with one of my Sting Rays. I hand tightened the fitting on the intake and then used a wrench to tighten it another 1/4-1/2 turn and "crack" it went. Unfortunately, MDM charged me $50 for a new one. I think the wet end housings on the reeflo line are pretty cheaply made. The housing on my 3200 seems to be about 10 times stronger. Good luck with the new setup. I'm looking forward to watching it unfold. |

Travis Thanks for your comments!
My Hammerhead does not seem to run all that warm. It is warm to the touch, but definitely not hot. Does not seem to heat the water more than about 1 degree. My calculations are kind of in my head. According to kthsales 3 or 4 eductors works well on an Iwaki 100. I can't remember all of my calculations at present but, I believe that means that 4 to 5 should work well for the hammerhead giving the amount of backpressure the eductors create. I figure the Hammerhead will deliver about 2400 - 2800 gph with the eductors, resulting in less then 10 PSI. I am not worried about this though because I have used the eductors at around 5 PSI and they worked well. At anywhere from 6 to 7 PSI upward they seem to still multiply flow by about 5. (I can back this up by personal experience) I wouldn't go less though. This should give me between 12000 and 14000 gph in tank flow from just the closed loop. I do like redundancy. However, in this situation I feel that I can take the chance. The tank will still work fine without the CL pump working. Of course if I were on vacation for a long time I wouldn't want this to happen. I feel that I can take the chance, because I will probably eventually end up with 2 - Blueline 70 or 100 return pumps. Both of these will run eductors as well. . This should result in at least 10000 gph additional flow. So, if the return pump failed, I would still have 50 times flow in the tank. (Grunt, grunt)Not on an OM 4-way, but adequate non-the-less. I can hardly wait to get my new volute for the Hammerhead. I will try to post some videos of the flow when I get it up and running. |

WaterDogs Thanks for the compliments. I will consider using silicone on the bulkheads.
Does silicone actually stick to PVC or does it just act like a gasket? I hope I am somewhat successful at keeping SPS. Living here in Canada, I have hardly even seen any SPS corals except in pics. I wouldn't even be trying if it wasn't for RC. |

The silicone will stick to the bulkheads, but you have to clean them real good with acetone or denatured alcohol.

I just noticed you are in Winnipeg. Before I turned 21, my college buddies and I used to go up there for spring breaks and New Year's Eve's. I think I was up there about 5 different times. We always had a blast! Very cool city.
FWIW, I've never put silicone on my bulkheads and never will. It simply isn't needed. I've never had a problem with one leaking. IMO, you don't need to use silicone, especially since you are using sch 80 bulkheads which are a lot "meatier" than the sch 40's. |

This thread is great. I can't believe all the holes you have in your new tank, but it's gonna be awesome. Are you putting a sheet of 1/2" rigid foam between the wooden platform and your new tank? Mitch told me to do so when we were debating that topic about my new 280g. So I did.
I too have never used silicone on any bulkheads. The rubber gasket goes on the inside of the tank, and you tighten from below. Tighten well, but don't overtighten. Since you stated it is harder to get SPS in Canada, I'm wondering why you chose to build such a large SPS tank? Do you plan to drive into the U.S. to get your livestock?

As far as SPS goes, I have one LFS that can get me frags. I have no idea how good they are. I do plan on driving to Florida for a vacation maybe this winter, and picking up some frags on my return. Maybe some generous souls reading this will offer to have me stop in to their place and relieve them of their crowded grow out tanks! Thanks for the remarks. |

I was thinking you'll have problems with customs if you import your corals, plus the additonal taxation. If you drive them in you might avoid some of those issues.
You might even find a reefer in the upper most part of the states to have your stuff shipped to, then you meet at that point to bring it to your home. Admittedly, I miss many threads as I tend to focus on the ones I'm subscribed to, so if someone wishes for me to participate in another, a PM is all it takes. I was just out trolling for new threads last night and discovered yours amidst the "what is this?" and "are aptasias really that bad" and "why can't I use bioballs!?" Just kidding guys, we all asked those questions at some point, including myself.

The rubber seals work great at first, but as time goes by and SW deteriorates it, the seal hardens and takes a set then seepage starts and the bulkhead works loose; so given the rubber is only there to seal, by using silicone only the bulkhead can be both tight and will not work loose. Rubber and silicone is a bad combo pick one or the other. Get the details if possible when someone says they never have a problem doing it such and such a way; things like how much time has gone since a seal was put into service, etc...

Hey Little, looking great
I have a question. Sorry if you already stated in an earlier post, I am on a very slow dialup until the weekend. Are you going to use check valves under the tank? I'm now looking into the 4way OM unit and I will probably drill the bottom like yours but I'm not sure if I would need check valves just incase the pump/plumbing were to leak??? Kinda scary to drill the bottom like that. I would just silicone those bulkheads in just to be safe. As water said don't use the rubber if you do silicone them in. That tank looks huge with you in it,lol. Looks like they gave you quality adjustment screws on the hinges too. Most of the cheaper ones I've used always break after a few turns. Then I have to tap them out or throw the hinge away. Keep the pics comeing. |

It looks like you used the white styrofoam, and I just wanted to tell you now that you need to replace that with the pink stuff from Home Depot. The white stuff is a kind Mitch told me to avoid using because it compresses too easily.

I'm still a bit iify on the siliconed bulkheads issue. I am not sure that silicone actually sticks to PVC. Then when a bulkhead is turned it could break the silicone seal and cause a real mess. With the rubber gasket, even if the seal is turned slightly it won't start to leak. Anybody with a 7 year old tank with original bulkheads? Also, the hinges are kitchcraft. They are actually very easy to adjust. I took the lower doors off and put them in the basement for safe keeping. The gigantic hood was placed on the tank today, and I am quite proud of how it turned out. It is not done yet, but the doors work very well, look good, and are make accessing the tank a breeze. I will post pics shortly. |

surfy Just another bit of info on the 4-way. I will have a ball-valve on each of the outputs of the 4-way. Also I will have a quick-disconnect on each output. That way I can remove the unit for cleaning, if the need arises.

With the rubber gasket, even if the seal is turned slightly it won't start to leak. Very good point. I was actually thinking about that after I posted. I guess the safest way would be to just use the rubber gasket and silicone heavily around the bulkhead. Even this way can break the silicone if the BH is over tightened. I wonder if superglue gel would work? Thanks for the heads up on the 4 way. I still need to study it further. My new tank will be here next week so I need to hurry and make up my mind. |

Silicone & Rubber gasket. Mine is dry as a bone. Just my experience. So far so good.
