i have a 4 foot high rex reactor on the output of my fx5 works like a champ
If the CO2 is getting mixed and dissolved in your canister you won't see any micro bubbles. A drop checker can take 2 to 3 hrs before you notice any change. What size tank and how many bps are you outputting? Are you using 4dkh solution in the drop checker? What actually occurs when your filter does the auto purge? How does it do it?I have been feeding co2 through the intake of my FX6 for about a month now. I understand the whole killing bacteria thing, but my fish have been just fine.
I am not entirely convinced that the co2 is being dissolved through my canister. I don't see a single micro bubble coming out of the outtake. I am worried that the co2 is building up in my canister and gets released in mass during it's auto-purge/prime periods.
I just installed a no-name ISTA drop checker and it displays blue.
Thoughts?
