water tempeture in a planted tank

I am on the other end of the thermometer so to speak.....all my tropical planted tanks are 80-82F, and of course the discus is 86F.
 
I keep tanks between 79F and about 82-83F.
I cannot keep them cooler during the hot summers here.

Plants will grow faster at warmer temps, slower at lower temps.
Increased metabolism with increasing temps.

Same for DIY yeast etc, it will produce more CO2 at 30C than at 20C, quite a bit more...........

So add more ferts/CO2 at higher temps to account for it.
It has little to do with preference if the supply load rate is being met equally at two different temps.

Since many do not account for that, they might be tempted to think that the plants have a preference for cooler temps. Cooler temps would be easier for management of a planted tank, non CO2 or CO2 enriched.

Since it slows the rates and thus demand for light/CO2/nutrients down.
If you use higher temps, good CO2/nutrients, and low light, then you also have a good way to manage growth with the most wiggle room as well.

Temps are hard to control in many regions due to hot summers.

Cardinals will not do well at cool temps, they do not feed well etc and many other fish fall into this group. Some suggest 86-88F, but 82-83 is fine for them/Discus Altums etc.

For some species of shrimp, 60-74F is ideal, CRS, RCS etc do very well at cold temps, but start to do poorer at higher temps, say over 78-80F.

So species you plan on keeping, and if you can maintain those colder temps year around are important issues/questions you need to ask 1st.

Plants are fairly tolerant if you account and add more /less depending on the rise/fall of temps.

In my Aquarium / Computer room the room temp is always 78 degrees. Even in winter time without running the electric heat in that room the temp stays the same.
Computers heat aquariums for me.

I have all my tanks set at 72. I have all kinds of community fish.I have the following:

Angelfish,bushy nosed pleco, harlequen rasboras, bubblebee platies, Black chin,panda platies,dwarf espis,boesmani rainbows,tiger endlers, hifin mollies,mystery snails,assassin snails,yellow shrimp, red cherry shrimp,tiger shrimp.I used to have glo-light tetras in the tank but since rehomed them. All the fish I have are doing well even though some are used to warmer waters.

I also have a planted tank with low-light no C02, Black sand mixed with eco -complete, and pool filter sand that I put plant tabs in some plants.The plants I have that are doing good are:

Wisteria, Java fern, Java moss,Taiwan moss,Wendelov fern,Willow leaf hygro,Anubias,Dwarf sagittaria,Water sprite,Vallisneria, Spiral vallisneria,Cryptocoryne wendii red,Cryptocoryne wendtii, dwarf sagittaria, Chain sword. Some of these plants melted at first from the roots being tampered with after buying them but came back ok after I cut out the melted parts.

How do you set it , do you run a chiller ?
