For a 10 gallon cube I'm looking for a nano calcium reactor
Thank you Mr. Coral for your information. I'll just do the water changes. Just been super lazy lolFor a 10 gallon tank, a calcium reactor can be difficult to dial in. Due to the output of a calcium reactor is acidic, it can easily kill off your tank if adjustments is not precise.
Dosing pump or large frequent water change are much better options.
If a calcium reactor is a must have for you, I can order an AquaMaxx hang-on nano calcium reactor for you. I never see a used one on the market.
