Needle Valve and Pre Filter question
1st question should be so bad. Anyone know of a good prefilter for a Marineland Penguin 100 filter? And a prefilter for a Whisper 2 Power filter?
2nd question is a little more difficult. My co2 is now running fine and all, but for some reason I still cannot get the bubble count higher for my 75 gallon. The line for my 10 is working just fine, and I can easily raise the co2 more than needed, but I'm struggling to get 2bps into my 75....when really it should probably be at 3 or 4 to get the drop checker green.
I think it might be that there is a leak between my needle valve and my manifold, but I'm not sure how to test that. Can the soap and bubble thing be used? Or would that screw with the teflon tape on the needle valve?
To be honest, I think I didn't use enough tefflon tape when I had to re-attatch it to the manifold, but the way it is now, I'd have to take the manifold off of the regulator in order to adjust this needle valve, which I want to avoid doing because the 10 gallon needle valve is on that manifold.
Btw, while on the topic, what are the best needle valves out there? I might want to replace mine at some point in time, just not sure what the good ones are.
