I'd like to pick your brains about the best co2 injection methods for a planted tank that is running an overflow and a wet dry.
Here's some specs on the equipment I'm using for some background.
The tank is a 60H that has been drilled for an overflow. I'm using a glass holes super nano overflow kit
. There's about a 1 inch drop for the water. The box has a lid but it is not sealed.
The water flows into a CPR style wet/dry filter with the wet/dry section sealed.
The return pump is a sicce 1.0 silent syncra pump that runs at about 230gph.
I have several methods of injection at my disposal and would like to know what would work best.
Method 1: My current method. I'm running a phosban 150 reactor for purigen, so I have one of those atomic inline co2 diffusers on the pump side. It injects co2 into the purigen reactor, then the co2 infused water is pumped back into the wet/dry near the return pump.
The issue with this is that I can't run the reactor pump at a high GPH since it'll shoot all the purigen into the sump. because of this, I get a lot of larger bubbles that collect near the top and eventually get pushed out of the reactor. These bubbles are probably the size of a large pea.
Method 2. I ran the atomic inline reactor on the return pump. it worked well, the only problem was the co2 mist. I hate the look, it makes the tank look very cloudy.
Method 3. I had a regular atomic diffuser that was placed in the sump. It was plumbed into the wet dry section that was sealed off. I only had it running for a day or so so not too sure how well this worked.
I don't have room in my stand to build another stand alone reactor like a rex grigg so that is out of the question.
I was thinking about maybe running the atomic diffuser on the drain pipe so it shoots the co2 straight into the wetdry chamber that is already sealed off, but don't know if this will actualy work in practice
Thanks for reading and for any input!
