Cooling tank

ejl2529 · May 15, 2020

I have a 32.5 gallon Fluval Flex Saltwater mixed reef tank. I was wondering what the best item to cool it would be besides using a chiller. The dimensions of the tank are roughly 32.5L x 15W x 15H inches. Ideally I am looking for something that could run automatically, such as a fan with a temperature sensor. The hottest my tank would realistically get would be around 85-87F. Thanks for any help.

Check out my post on EcolibriumReef, a DIY Arduino controller.
I am using it on my 120 gal, 4x2x2 with two computer cooling fans and my water temperature is always under 81° year round. Nice thing about using fans for cooling is that water evaporation takes away heat regardless of the surrounding temperature with very little energy usage compared to a chiller. It would be great if you have an auto top-off system, which is also a function of EcolibriumReef. You can find more information on GitHub

You find a soultion? I added a second light and having the same issue, temp getting at 84 at the highest right now.

I need tips to cool the water

I have a nano 13.5 reef tank. The water is always above the ideal 76º I want. The heater is set much lower just to rule it out as one of the possible causes for my high temperature, which is always around 80, so it probably never operates. I understand that the ratio of equipment running...

I added a Petzilla chiller fan to the side of the tank. However, I don’t use the lid for my tank so I don’t think that would work for you if you use the lid.

What lights are you using? Yea I still have the lid with 2 lights

I have 2 AI prime 16 hd. They work really nicely and they fit perfect spaced out in the slots next to the overflow. I was also able to modify the lid to make it fit over the overflow box.
