Drop-In Water Chillers?

[Mark Haseltine]

I had a problem recently with an extremely unreliable Rio submerged pump
running my wet-dry filter on a 75 gallon sal****er tank. It failed during a
power outage while I was on vacation, and took out the majority of the fish
in my tank...I'm still recovering from the carnage.

I immediately went out and replaced it with an external (non-submerged) pump
which fixes the reliability problem, but now the temperature is way, way up
(around 87 degrees F) even with the air conditioner running full tilt. So
I'm thinking I need to add a chiller to keep the temperature under control.

I've looked around, and I think it would be easiest for me to install a
drop-in chiller. I'm wondering if anyone has any experience with these. Is
there any specific brand or model you can recommend (SeaLife, Cyclone,
etc.)? An online store that sells them at a reasonable price?

Thanks in advance.

2F on a 75

the easiest is a bigger fan over the sump :)
cheaper initial cost and runtime :)

damn it how stupid of me, forgot to answer the rest of the question

the dropin chillers are nice but generally are not as efficient
often more $$ for less efficiency

A standard sal****er tank with a wet/dry filter should not need a chiller.
You mentioned, now that you replaced the pump, the temp is way, way up.
What pump did you get? I can't see buying a chiller to combat a single pump
that is causing a problem that I assume you did not have before, based on
your statement. There are plenty of pumps available that will add minimal
heat to the water. Plus, consider the drawbacks to a chiller. It may be
noisy, add additional operating costs, blow heat into your room, etc. I
can't see that being worth it in this situation.

Furthermore, you're Rio was submerged which will add more heat to your water
than an external pump like you just purchased. Something just doesn't sound
right here. If anything, you should have experienced a temperature
drop...unless the new pump is an older style Rainbow Lifegard Quiet One or a
new Custom Sea Life pump. They run silent, but do add considerable heat to
the water.

On my 54 gallon sal****er wet/dry system, I'm using one of the Rainbow
Lifegard Quiet One (older style) pumps that I know was causing temps into
the high 80's as well. Since the warm weather is only a 2-3 month problem,
I use the fan method as well. A $10 Holmes clip-on fan from Staples, aimed
at the sump water. It dropped the temperature about 4 degrees easily. The
only drawback is the tank now evaporates about a 1/2 gallon of water per
day. It's a small nuisance, but overall no big deal. I just keep a large
container of RO/DI water handy. A simple solution guaranteed to work. If
you're maxing out at 87, you will get your tank back well into the safe zone
with a fan.

Good luck!
