temperature affect plants?

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?

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

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

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?

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?

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?

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.
