Water temperature for Wilds

[wannafish]

I have been trying to look up information for temperature with Wilds.
And I am concerned with ambient temperature in my room that may
cause the temperature in my tank to lower. What I have read is that
if the ambient temperature is low it will cause the heater in the tank
to stay in the on position and may not raise the temperature in the
tank. In the summer the ambient room temp is 70 and my tank
is 90 and my heckles are happy.
Now that it is winter the temps are lower, and the ambient room temp.
is in the 50's and the temp is in the lower 80's. But I don't know if
that is accurate during the night. I am thinking about adding another
heater to compensate for the one heater to be overworked and not
warming the water.

Yes, you should at least one more heater to take the stress off the existing one. As you said it will be working very hard 24/7. If it fails you will have either boiled your fish or they will get too cold. In my opinion 2 heaters are the bare minimum in a tank that size.

And if your room temp is in the low 50’s I’d seriously consider heating the room or moving the tank.

[Swedgin]

As for the temperature for the fish, mine are doing well at a minimum of 82. Personally I would not go any lower than that.

Also, 90 as a long term environment is unnecessary. Other than for some sort of treatment, there is no reason to go over 85 or 86, in my opinion/experience.

Thanks for the quick response. It's not feasible to warm up the room,
that's why I am concerned. I would hope that adding the second
heater keeps the tank warm enough and in check for a comfortable
environment.

I'd look into insulating the sides as well if you can. Plus another heater

you could also put foam board insulation on the back and sides of the tank. That will help the heaters keep the tank warm by reducing the heat you lose into the room. Does your tank have a lid?

[wannafish]

No lid. But I think I will get some insulation and do the sides and front
during the night, and take the front panel off in the morning. It's just
for the next three months maybe less.

Just for what it's worth......and I'm no Discus guru, I'll share my specific set up for tank temperature. I have a 75g tank w a 20g sump and my tank temp is a steady 87 degrees. I use a Bluline heater controller set to shut off my heaters at 89 degrees should the heaters malfunction. I plugged in two 200w Finnex Digital Controller Heaters set to 87 degrees into the Bluline with my fish thriving. My room is warmer than yours, but two 200w heaters would prob. do the trick for you and your 90g. In addition, I have a Lifeguard Big Digital Temp. Alert set for a minimum of 84. If the temp reaches/falls to 84, an alarm sounds. This way, I have my too high and too low temp. levels covered. I also have two other regular Mercury thermometers and a Topfin digital thermeter in the tank to double check all the temp. settings. If u r interested in going this route, let me know and I can post pics or list links for you. Remember, this is just my set up and others may agree or disagree. My temp., for example, is one degree higher than Swedgin said was his range. This is not an exact science and different methods work differently for different Discus keepers.

My good man get a glass cover or cover of some sort. Your losing far too much heat too fast without it. Yes foam board will help a ton but heat rises and the surface area the heat is rising out of pretty large.
