local tap water

[rickwaines]

So,

Do folks in the lower mainland use water out of their taps for their tanks? The water out of my tap has a TDS of between 4 and 7. quite low no? I ask because I have been having some bryopsis algae problems. There could be many different causes and I am working on sorting it out but My one of my questions is whether or not I should invest in an RO/DI unit.

Thanks, Rick
