Hello friends. I have a problem I need help with. I cod a tank of 440 gallons. I bought poseidon 200 and air dryer from BRs. I am using a primary skimmer and have a problem with using Ozone. I used 1 tee piece to connect the skimmer to the ozone and the other end to the co2 scrubber. I did not find ozone to be effective. have tested and confirmed poseidon 200 machine working properly. I'm planning to use a small skimmer to make an Ozone reactor because I can't afford a reactor in my area. Thank you guys. Looking forward to getting advice on the type and capacity of the skimmer just to run the ozonr reactor for my tank. Thank you guys.
