Hi everyone! This is not directly related to reef tanks, but I still thought this would be the best place to get this question answered. Anyhow...I have had a blackwater tank set up for a little over a week. The tank has very soft (TDS less than 25 ppm) water, and I am planning on acquiring that water in the long run by passing dechlorinated tap water (with a TDS of 40 ppm) and rain water (depending on availability) through DI resin.
What I have been wondering is, 'Would it make more sense to make new blackwater by passing old tank water through the resin, instead of the tap water? Or would the tannins rapidly wear out the resin even though they have little impact on TDS?' Thanks
