Diy C02 causing surface film
Arg, is happening again. My DIY C02 is causing my tank to have a surface film.
i know is from my c02 because i did a test and stop putting c02 in the tank for 3 days, there was nothing on the surface, then i put in c02 and 3 days later, there are bubbles... Its really nasty because then when i mix the surface with my hand, white strands go into the water.
Now, i could just raise my spray bar (xp3 running in a 20 gallon LOL) but that doesnt really solve the problem because its still there, just mixed in the water column now. I kinda want to get rid of it because im afraid that if i do use the spraybar pointed upwards, it will degas too much c02.
