I know this must have been discussed a million times over, forgive me. I searched the forums, also searched the net but am out of ideas.
I have a 10g planted tank with a DIY CO2
system. I use a 1 gallon jug instead of the 2l bottle. The trouble is trying to figure out a method of good CO2
I don't want to deal with a DIY diffuser involving a small pump and tubing, I looked into it as an option but it takes up considerable space.
I tried hooking up the line to the intake of the HOB
Tetra Whisper PF10 filter, but it causes the impeller to rattle when it's sucking in bubbles.
I hooked up an airstone and placed it next to the filter intake. It still rattles when it takes in the CO2
bubbles but now most of them escape to the surface.
I played around with placing the airstone somewhere inside the filter: under the mechanical filter, close to the impeller. Same result: I see the bubbles raising up straight to the surface.
Any tips are greatly appreciated. Worse come to worse I have a Hagen Elite Mini pump with a venturi system. I tried using it but it intensifies the current in the tank even on the lowest setting AND it takes up some space.
And because I keep fiddling with this, my pH has swung over the course of 3 days from 8.3 down to 7.8, 7.6 and now back up to 8.2-ish.
