Hi im all new to this water fed pole lark and i was wondering do you have to let the water run from the poles for a few minutes before you clean from a new tank of water?
The reason why i ask is i check the tds at the start and its around 350-440, but after 3-4 mins its down to 007 then after the first clean i check and its 001-002, is this normal or am i doing something wrong or does a filter need changing???
