My tank cools right down over night when its very cold. The heater finds it hard to keep up. The thermometer reads 27/28 during the day but drops to 23/24 over night. Is this ok for the fish? The heating in my house isn't on over night and my kitchen becomes freezing!

I have a 50w heater and the tank is 38L. This kind of heater is good up to 50L apparently. Do people still think I should get a better heater?

Buy a thermometer with a green "band" on it.
That's your safe temperature range. If it drops out of that range, you get a better heater, if it stays in it (which I believe 23 is) then you're ok

It is very dangerous for the fish, they are tropical and need to be in a constant warm temperature needs to be kept at the same constant all the time and they will die if it gets to cold. Would it not just be easier and cheaper to by another heater and use both ? you can run as many heaters and filters as you want in a tank. In the end you will loose your fish and it wont cost any more to install another heater because they turn off when the water is warm enough. good luck with them. I used to breed them and know what I saying but they got a bit much for me. best wishes.

Best to instal a heater of at least 100 watts. Get an electronic heater-stat as these do not have a mechanical switching device & don't jam On or Off, so avoiding a freeze out or a boil up.

If your heater can't keep up you need a stronger one or to put in an additional one. If your fish are temperature sensitive (& tropical fish usually are) then you really need to take care of it quickly.
You can also get a red colored light that you can put on at night. This will help heat the tank a little and most fish can't see red light.

It usually depends on the fish, they will do alright if the temp drops slightly over time, but if it just drops, it will kill them, obviously. They won't die unless it gets down to like 15 C, but they will be very very inactive and freezing already when the tempo drops to 23 C. I would get a stronger heater if i were you.

A lot depends on the species you are keeping, however, that large of a temperature drop is considerable. You should probably get a larger heater, 10 watts per gallon. (2.5 watts per liter). A heater that large can create problems on its own,such as increased evaporation,which leads to an increased need for water changes. Low temperatures can bring on massive cases of ich,even temps control it. Hope this helps. PeeTee

a drastic change like that in heat can cause the fish alot of problems....they may not have had problems yet,but that doesnt mean they wont,you really need to get a heater that can do the job.

im pretty sure tropical fish tanks need to be kept at a constant temp.
Can you not set your water heater to keep the water at the required temp?

I have a 350Lr tank and it has one 100w heater keeps a steady 25c without any problem and we have no central heating. My fish are marines and they would not tolerate constant changes. I doubt it is doing yours much good.

Just get a heater. They really don't cost that much and temperature fluctuations aren't good for fish.
