Hi My name is Von and I live in England.
I have just bought a Garra Rufa spa. It has two identical tanks, two identical fiters, two identical pumps, two identical heaters and both have brand new identical uv lamps.
My problem is although everything is identical, right down to to percentage of water in the water change, one tank has discoloured water and the other is crystal clear and they sit right next to each other.
Any suggestions would be much appreciated.
