Chiller Size Question

[ChrisC5150]

Hi all! I have a 55 gal mixed tank w/ 30 gal sump that I would like to keep between 78-79 deg. It’s already starting to get warm here (86 today) and my tank got up to 85. I have a fan blowing on it now but I’m thinking I probably need a chiller because we set our house A/C to come on at 82 normally.
I’’d appreciate feedback on what size chiller I should buy. Thanks

Holy you set your house AC to come on at 82 that’s very hot bro you are going to boil that tank, why so high that’s pretty hot, i keep my temp set at 66 with a ceiling fan running 24/7 365, did you check out BRS, it’s no going to be cheap for you bro i would guess it’s going to run you $750 or more, i keep my tank right below 74 i don’t like to get it up near 78 it’s to warm

You can get a free 1/10 hp chiller. Sizing up a little is always better as the chiller turns on and off less and runs for shorter periods. However, if you have a controller I would first set fans to go on and then the chiller as a backup. I don’t know if your tank is in a room with a separate zoned AC as 82 is pretty hot to have your house temp set to. Are you sure you didn’t mean 72?

Actually, a smaller chiller works better than one that is too large. A smaller chiller cools the water down slower and wont short cycle like a big unit will. A 1/10 Arctica will serve you well for many, many years. I live in Phoenix and didn't like the humidity a fan produced so I use a chiller and love it, I can set the house AC to 80 and not have to worry that the tank will run at 84 lol. I set my chiller to 80 with a 1 degree temp differential.

Thanks! How do I go about getting a free 1/10 chiller?

You could make a diy chiller out of a minifridge but idk how you'd go about regulating it. At any rate id imagine it would be cheaper to just keep your house at a more civilized temperature.

“Free” must have been auto correct sorry …..

I have an Jbj arctic 1/3 HP and it can easily keep 350+ gallons down to 78 in a room well above 85 degrees. I don’t really use it much anymore though because I bought a mini split ac for the aquarium room. I hope this helps somewhat.

I just bought a 1/3 hp chiller. Before I left for several days with my A/C set on 77. It got up to 80 and I lost most of my invertebrates. Now it takes about 10 minutes to bring my 75-gallon tank down 1 degree. I'll still have to keep the A/C on but much higher just to keep the excessive chiller exhaust down.
