Re: temperature affect plants?

Hornwort, both submersum and demersum will say bye-bye at 34C. This is not
a great temp for most fish, either. Most mosses, like it cooler, too--is there a
reason to have this high a temp?

Re: temperature affect plants?

my discus is not making itself well at home.

but I am planning to sell it because it ain't fitting into my aquascape that well.

I have a very amano like aquascape...and the discus is not happy with that much open area.

Re: temperature affect plants?

Yeah, I like shoaling fish, small, to increase the effect of another world :)
Tom has several species in his 350 gallon tank, same idea.

ps I always thought the dinner plate fish as subtractive to a good 'scape,
but there are those who are slap in love with them :D

That's 86-93F for us non-metric folk. :p

That's higher than any recommendation I've ever seen, even for Discus at the 93F end. Many plant shops offer Discus tank selections, but I've only ever seen 86F as the upper recommended limit.

My 90 gallon went into a mid-90F death spiral and pretty much every plant died or suffered mightily. Add a fan across the surface, run the lights at night when the house is cooler, shorten the photoperiod and/or reduce the amount of lights to cool things off. I added a radiator and reduced the amount of lights, so now it stays in the 74-80F range.

I'd really like to keep a couple of big fat fancy goldfish in that tank, but they prefer around 68F and I can't get there without a chiller. I refuse to go that route, but I'm testing it out with a smaller less fancy goldfish.

Re: temperature affect plants?

Is there a fan you recommend for going across teh surface? Can you add a second fan to a coralife aqualight.. what is a radiator?

my tank keeps creeping up to 84 degrees and I need help cooling.

Re: temperature affect plants?

Raditors use a simple evaporative cooling, not sure why they are not more popular for aquariums, but the chillers are well established and no one really has done much with them. Swamp coolers work well is some locations where the humidity is lower also.

Just think about a car radiator....hot water comes in, air movement, cooler water returns. A fan across the top of the surface will help and is essentially a fan swamp cooler.

Re: temperature affect plants?

My 110 watt AHS lights on a 29 gallon tank were heating the water to 85 F so I installed a 40 mm diameter 12 volt fan in the end of the canopy, blowing into the canopy, with air exhausting out the vent holes on top and in back. I run it at about 6 volts, and the temperature now tops out at about 76 F. That's a very small fan too. I am evaporating some water, but it is well worth it.

Re: temperature affect plants?

The original question hasn't been answered though. I am interested as well in the point of the question which is: can a planted tank be maintained at discus temps in the neighborhood of 85F without negative repercussions, or are temps in the mid 70's really better for the plants.

Re: temperature affect plants?

I've bred discus repeatedly at 82F, I see no reason to keep them at high elevated temps that breeders suggest. If you are after maximum brood production, planted tanks are not a good option.

Plants are fine, but things happen and little faster as you increase temps, this makes things a little tougher to deal with.

There's no need to keep them at 86F, a middle ground at 82F is fine for most all plants excpet a few Aponogetons and few mosses.

Re: temperature affect plants?

Did you have any problems with overall health of the fish in the long term? Like occasional parasitic infection or poor color?

Re: temperature affect plants?

Never had a disease, never had any issues, the fish bred after all... repeatedly. Several other folks that I'vwe set up discus tanks for have the same problem with their fish breeding all the time.

Re: temperature affect plants?

I keep my discus at 27-28C (80-82F) and have not had any problems with them.
They dont need high temperature as long as they are well taken care of and the water is in good condition.

Re: temperature affect plants?

I think good water quality, water changes, good foods, less live foods such as those sewer wroms, black/tunfix, frozen is fine, so are brine, red worms(fishing earthworms), special dry foods.

They are big old cichlids, not wimpy fish, even the wild ones are not that picky.
