Calgarys' water...

[TANGOMAN]

I was just lookin' at Wayners' posting on the Reef board regarding carbon filter replacements for RO units and began to wonder what the locals are doin' to "pre-clean" our tap water. I don't use RO water. My heads still spinnin' from buyin' our first house. I found a bunch of standard size, house filter "canisters" for $10.00 @ Home Depot last year so I picked up three of them. The first contains a carbon filter cartridge, the second a GAC cartridge, and the third one I still lay in bed at night thinkin' of a use for... I was still getting an occasional "cyano" outbreak in my 60g and I began to think maybe there was excessive phosphates and/or silicates in the tap water so I made a "cylinder out of 1 1/2" PVC, filled it with "KENT Phosguard". Took care of the cyanobacteria but I still get hair algae problems in my 90. Bla,bla,bla, eh? Is RO/DI necessary or is it nice option.
p.s. Faiview Fittings is a great place to pick up nylon fittings, 1/4"MPx1/4" comp. etc. for those "home-made projects that never leak in the middle of the night"...
