Air disk Qty

I do have a ice probe I installed into the side of the bucket, keeping if at 66 , so I think I’ll run it with both air disk. Thanks

The more air the better, but it's better to use bubblers that throw tiny air bubbles. That and keeping your water cool is very important. If you keep your pump somewhere where it can pull cold air into it they wont heat the buckets to much. More the light that heats buckets. You can get wrap insulation for that and frozen bottles of water to throw in throughout the day if you havent got or cant afford a chiller. Water holds oxygen best at about 60 to 68°. Cheers friend
