Chem geek,
Thanks, i can,t stop running the pump there is a small pump running 24 hours a day.
The only way is cut off the power but then it is completly off, i try to raise my chlorine and when i,m back home i check the water (but i think i change it), it is simply the best.
And indeed we have no AHHSOME, but i use tube clean, it is the best i can get in the Netherlands.
