After we had the winter discussion what to do and how to heat tanks when the ice storms knock power out I'd like to pot the equivalent for the summer time....
As your house get's warmer and may only read 70's in your house and that feels good to you with the fan on you have got to consider & check at this point already what your tanks do as far as temp is concerned as their lights will produce a certain amount of heat as well; also the tank may get direct sunlight during parts of the day which heats up your tank. These 3 matters combined and yu can quickly wind up with your tank reading 90's.
This will apply even more so when you have smaller tanks, here's examples from today in my house:
Its 75F in here my 10g shrimp farm with no sunlight but just the bulbs for light just read 88F which is getting very boarder line for the shrimp.
The 55g naturally stay's cooler then the shrimp cause of its size vs the heat from the light, however it gets about 30mins sunlight in the PM it read 85F.
My 45g in the hallway close by a fan and no sunlight reads 82F so its perfect.
So just keep an eye on your tank these days before the A/C "season" starts and if its getting too high do a w/c with cold water on the tank in question. If you have a tank that get's too warm at a particular time a day due to sunlight - Just take a 1-2 liters Coke bottle filled with water & frozen and hang it in there to keep it at a decent temp for the fish.
Tropical fish or not too much heat is as bad as no heat, so I just wanted to post a lil reminder for ya'll
