Ttm issues

[spsrookie]

So I have two ten gallon tanks for ttm, with 100 watt jager heaters.

Today was transfer day, and I had both set up at 79.

Tank 1 was set at 79, and after 24 hrs, was still there.

Today right before the 72nd hour, I measured new water 79, and tank they were coming out of, 84 somehow.

It's the heater and pump, no lights, in a cool room. The pump is tiny, about 20 watts.

I transferred them ...is 5 degree swing from one tank to other too much?

Depends on the fish probably. I know I subjected my clown to multiple temp swings like that. She's still fine, though certainly wasn't thrilled at the time.

Gotcha. Staring not to trust heaters in general

i've had loads of issues with bad internal therms in heaters.

i have a few heaters that are set on the dial to 72 degrees, but heat the water to 80 degrees every time.

so i do two things:

1. i pre-calibrate my heaters to the temperature i want, regardless of what the dial says.
2. i check the temp (and also salinity) in my TTM tanks twice a day. once in the morning and one in the evening, just to make sure things are stable.
