So I have several hunches on what is going on but heres the full context of my issue. Bubble counters on my multi co2 regulator broke bc I am careless and knocked over the co2 tank being a goof. While searching for replacement bubble counters, the ones that sit on the needle valve, I saw a few co2 diffusers and mine were caked in algae so I grabbed one to test for a week before buying another one for the other tank. Everything seemed ok on the one I bought so I bought another one and replaced my old one. Yes I am aware there is some way of fixing diffusers covered in algae but they were cheap ones and the toothbrush thing didnt work. I noticed that my co2 bubbles were inconsistent and I was always getting home and adjusting them more open. I even tried increasing the psi to 80, dont recommend lol but gave up and assumed the tank was low on co2 so I replaced the tank.. Now I am having issues dialing in only one of my needle valves and the other is actually doing consistent output. Just got home today and figured I better just give in and ask the forums if anyone knows what this is, did I do this, how can I prevent this in the future, just 2022 guidance. Context given above, theory below. Theory 1: I believe the cheap little diffusers are somehow putting back pressure on the co2 lines. A few reviews complained about how high psi is needed which is why I tried 80 psi. Idk how to mitigate this except daily dialing in the needle valve until I reach equilibrium with the back pressure. Theory 2: It could be the bubble counters. I installed them together with one diffuser and the issue started exactly at that time sorta. The other algae ridden diffuser worked though... Theory 3: The needle valve is wandering/damaged and needs fixed. Idk how to fix this and all information I found online talks about back pressure from the line and the reviews of the diffusers talk about high pressure so maybe theyre experiencing back pressure too? Im completely lost, and even if I figure out whats causing the singular co2 line to slow down bubbles/pressure I dont know how to go about fixing it. Id hate to buy another co2 needle valve when the problem is something else Also, there are no leaks and I am using brass check valves which are semi new If youve experienced something like this or simply know how to diagnose or fix this thatd be great. I have a high lighting system now and am one day without co2 into having an algae farm lol -
I am told that part AV4, the needle valve often used for auto water change systems is not available. Alternative suggestions?
