Anybody ever make their own bubble counter ?
I'm discussed with these things. The first one I had was a total piece of crap. I replaced it with an Aqua Medic and wasn't inpressed with the quality of it either. Now I have a problem with it. The top wants to randomly pop up and out. The only thing holding it in is the fit of the O ring which seems to me like a bad idea.
It has to have a way to replensh the water as it evaporates and of course has to be co2 tight.
Anybody got any plans or failing that, can someone recommend a good quality bubble counter.
I can't believe this low tech piece has caused me so much grief.
