My TDS is creeping up,
so I think its time to replace my DI
And since the system was bought used 6 months ago.
I figured I would replace all the other filters also.
Will all (most) 10" Filters work on any RODI Unit?
I run a PurelyH2O Optima CA RO/DI.
Do I need to buy from them, or are theFilterGuys/Local stores the same filters?
(any suggestions on good, cheap RODI Filters?)
I assume you can refill your own DI filter or buy it prefilled
the first is cheaper (but might decrease the life of the DI left in the bag because of exposure to air?)
the second method is easier but more expensive?
Do I need to buy a Chlorine/Choramine test kit?
I think DC uses it, I'm just not sure if that is the cause of increased ammonia in my tank, even after a waterchange.
Thanks!
