Water Temperature is High. Effect on Plants?

I am not sure what keeps my temperature so high in my tanks, but I cant get it to drop below 81 at any given time. I keep my home heater at 72, and my AC on 74 during the respective seasons, but the air temperature doesnt seem to affect my tank temp.

My tank-heater is set at 77. And rarely turns on. My 180g is the same way, and actually stays at 82-83 most of the time.

The good part is that I plan on keeping Discus in the near future, so I need the high temps anyway.

What is the effect that this will have on the plants in my tank? I have Cambodia, Large Swords, Java Fern, Red Ludwig (sp?), and a couple others I cant remember the name of, but seem to be doing fine.

With the greater heat in the tank, is there something that I should add more of? co2 (17ppm right now), light (which is at 3.5wpg right now), fertilizer?

If the higher temp is fine, what is the max I can keep it at, since the Discus like warmer water. And what types of plants will thrive in there?

If you have a covered tank, try proping the hood open a bit to let air flow through & the heat out or have a fan blowing across the top of the hood which should cool the temps down a bit.

Some plants do better than others in high heat. Here are some that like the conditions Discuss like: Amazon Sword, Echinodorus bleheri, Echinodorus cordifolius, Sag. subulata, Val. spiralis, Water pennywort, Hygrophila corymbosa/polysperma.

Don't let your temp get over 85 degrees or you will have to use extra airation to keep enough oxygen in the water for the fish.
