Hi y'll, my first post.
I got a 72Lt fresh-water(i buy filter water as my tap water is bad) with water pump. My fish are basics(30+ mini random fish plus couple of bigger ones) and live well without the "current featured" of my submersed pump for a long time.
Since i removed the venti-cap, i love the movement and the bubbles but can't find a way to set it up right it changes over time and the bubble seems to be related to "gravity" somehow!?!? the lower i put the pump the less the bubbles!?
Would that be the gravity pressure on the rubber pipe for the air valve? If so would a stronger pipe allow deeper bubbles?
Any suggestion on pump settings and tweaks would be grandly appreciate, i ve been hacking at it for a while.
