I SEEM TO HAVE TROUBLE WITH PHOSPHAT EVEN WITH RO WATER THE WATER HERE (SUSSEX ENGLAND) IS HARD, I USED TO FILL BUCKETS WITH TAP WATER ADD WATER CONDITIONER BUT MAY NOT HAVE WAITED LONG ENOUGH TO LET IT GET TO WORK AS I WAS TOLD TEN MINUTES WAS LONG ENOUGH
FISH lots of tetra,plecostomus,clown loach,clown ruby cichlid,corydoras,molly,guppy i changed water on advise from shop and the guy there knows hisfish but may want to make a few quid
i have a tank that holds 640lt of water and was told to use RO water i changed it bit by bit over a few months now as money is tight the cost of the water has rissen to £4 for 75lt i want to know if going back to tap water thats treated is all that bad.
