Can tank temps influence cyano?

daddypugg · #1 10/04/2006, 09:06 PM

I seem to be experienceing a cyano (more like a dusting) only on the sand. nothing to serious but enough for some concern.

I have a 110 with a 30g sump/fuge, I have some caluerpa and cheato in the fuge.

I have noticed that my tank temps have been rising lately, I caught it at almost 90! I put an extra fan on it tonight to help lower the temps.

My question is can the temp influence this dusting that I am having?

All my params seem ok (well to me) but here they are:

Trate: 0
Trite: 0
Amm: 0
Phos: 0.1
PH: 8.4
Alk: 3.31
Calc: 410

Thanks,

90

I think I'd try to stop that from happening again.

0.1 PO4 is enough phosphate to encourage micro algae growth. You want to try and get down below .03 if possible.

Can you point me towards a better PO4 test kit? one that reads that low.

I just checked the temps again.... I guess I misread it - I am pretty sure that it was actually 86 not as bad as 90 but still high. Now it is at 85 and slowly coming down.

I use the Salifert PO4 kit. Works OK for me.

I see your in Florida but you should really try and get that temp down.

I'm trying I'm trying....

it normally runs around 82, I can't afford a chiller just yet so the fans are running for me.

I will try the Salifert.

Thanks for the info - I just got done reading the "CHEMISTRY AND THE AQUARIUM by RANDY HOLMES-FARLEY" article and now my head is spinning

What I gathered from the article is that my skimmer needs to be replaced (really undersized) and I need to up my macro a bit.

Come to think of it I just pruned a bunch of it back a few weeks ago and it seems like it isn't growing back as fast, maybe I need to check the lights over it.

try freezing water in plastic 3 ltre bottles placeing inthe back of tank or in the sump brings the temp down change bottles 1 or 2 times a day ....what does it take 5 minutes of your time,that is if vou cannt buy over priced chillers...hope this helps i did this right through summer months.

I thought about doing this but with my hours I wouldn't be able to stay consistent and then neither would the temps in my tank, and I would rather have temps a little warmer but stable as opposed to up and down adding extra stress to the inhabitants.

So for now I will use the fans and adjust until I actually get the chiller.

Yes, under certain unkown water parameters a rise in temp can induce cyano growth.

Perhaps because some bacteria and some inverts metabolize less favorable at higher temperatures and cause an increase in nutrients.

Thank you that is good to know, I have lowered my temps to about 82 as of this afternoon.
