Misting question

[rich311k]

How high in the tank do you keep your powerheads to diffuse the CO2. I have mine very low in the back corner and the adjacent corner and the front middle always has a touch of bba. The head is set to spray straight across the back. Should I raise it or would it be better to direct the flow diagonally? It is an AC30 powerhead and the tank is 36 gallons.

Thanks

I tend to keep them up near the top, then direct the mist downwards lengthwise through the tank for the best results, but you can try various other flow/current combos.

The goal is really to maintain teh CO2 mist and blast it around in the water column as much as you can.
