			 i remember a while back i tested our tap water with a tds meter and it read ~10ppm. ever since then i’ve been using tap water and seachem prime and i’ve never had any major problems. sure every now and then i’ll have some algae but i just assume it’s from over feeding or lack of water changes. i’ve never had any long term problems doing it this way but recently i’ve started a new tank and plan to go sps dominate. should i get an ro/di system?

			 also i don’t know if this makes a difference but my house is newly built (less then a year) so i think the water pipes should be clean right?

 So you are better off than the ones in my house, copper with leaded solder connections.  |

			 RO/DI is a PITA but well worth it. 
		
	
		
		
		
		
			I live in Coquitlam with some of the cleanest tap water on the planet but I still can't beat HA when I use tap water. Especially over time.
