high temp without heater or lights!!!

[littlesilvermax]

I have four T5s and two 6 foot VHOs and 3 250 watt halides and they heat my water by about 1 degree.

My Pumps (Sequence Hammerhead, pcx40, pcx50, pcx30, and Blueline 100) heat my water by about 14 degrees! Keep in mind all the above pumps are external, so they heat the water less. Submersible pumps heat the water by quite a bit.

It is a 72 gal and the powerheads are all hagen 3x201 and 1x402 plus the Mag350 for the skimmer.

I have noticed that the temp has started to decrease as the weather is getting a bit colder... My heater has been actually unplugged for 4 days now!!! I am considering of running without a heater even!!!

I wouldnt remove your heater. If the thermostat is working it properly the heater won't contribute to a heat problem but it will protect against a temperature drop should the ambient temperature get cold.

I havent used a heater since june. I am kinda concerned about the tank temp though in the mornings it will be about 73 and by night time it will be at about 79-80.

70???????????????????????????????????????

does anything even survive that cold tempreture, let a lone the big swing????

Anybody, is this normal, or even doable?

[1bigstud]

Sorry about that I had meant to put 73. Though I think stuff can survive in 70

That is still quite a big swing!!! Do you keep a reef or fish-only tank?

[1bigstud]

It is a reef tank. I agree that it is a big swing but it was that way for the entire summer and everything was fine. Now that I have my heaters plugged in it shouldnt be as bad.
