How do you guys get on with the ph when using water straight from the tap. The ph at my place is 7.6. Chlorine isn't a problem as our filter takes that out. I used to use proper ph 7 and aquaplus in 20 litre containers for a few days before doing a change. Recently the lfs put me onto using ph down instead, however I seem to using heaps of this as the tank regularly is 7.4 - 7.6. I've a 4 ft tank, with harlequins, neons, angels, clown loaches and gouramis. I've tested rain water at 7, but read the pollutents in the air nowadays make this a bit dodgey. Your thoughts?
