Warm tank w/ dart & eheim

[davocean]

I've been cycling my 180 w/ an eheim 1262 submerged for sump and a dart for closed loop.
I checked temp this morning and my tank is at 80 (house is at 72)
No lights, no other pumps.
When I grab the eheim I feel no heat at all.
The body of the dart is pretty warm, and I know people say that heat doesn't transfer, but that's pretty hard for me to agree with being that warm.
Anyone else have heat issues w/ these?

Are your light under a canopy? any fans?

The sequence pumps do transfer heat. My barracuda added 2 degrees when I set it up. My magdrive pump adds WAY more and its only a mag9.5 so IMO the sequence pump do amazing for the amount of water they push.

Do you have a glass or acrylic top on the tank?

I run the dart, a return pump, 750watts of halide, 320watts vho, Two 300W heaters, and still dont break 82 in a 72 degree house on a 150g.

I have a 150 with a mag18, mag9.5 and 3 seio 2600's and 2 other pumps and I dont nedd any heaters. They keep the tank quite warm. You might need a chiller if its so hot already, with the lights on its going to be pretty bad.
