RO/DI in vancouver?

[ed02zz]

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?
