Temperature

[KenB]

Was wondering what folks thought about temperature controller swings.  Mine has a 2 degree swing.  Set at 78 comes on at 77 goes off at 79.  There is another controller  that has a  +/- of one degree could set the low at 77.5 and high at 78.5.  Just wondering if it's worth it to go from a 2 degree swing to one degree?

I had a magnetic Thermometer, that my daughter used to chase fish around the tank with until she lost the outside piece, I haven't even checked my temp since. I know some keep 2 heaters in their tanks rather than 1 larger one.

 

I wouldn't worry about 2 Deg, a lot of people deal with bigger heat issues than that in the summer months without it hurting the tank.

2° isnt going to cause any problems. Fluctuations on the reef are considerably larger (though the inhabitants arent stuffed in a closed system).

KenB, What controller are you using now? Do you already have the other controller with the one degree deferential? My ACIII controller has a .1 deferential.

I have a JBJ controller and my heater just went up so I got two new 300W heaters and was thinking about upgrading to aqua logic controller.  The JBJ has been working fine for a couple of years now and doesn't sound like the 2 degree swing is an issue so maybe I'll stick with what I have.

I think after switching to LED from 8 x T5 bulbs my tank temp is a little more stable, but like I said earlier it's not something I really check anymore, I had my return pump burn out a couple of months ago and went without my sump for about a 4 days which also meant I wasnt heating my tank and I had no issues.
