Ph in tank is about 7.2, GH 6-7, KH 2-3, TDS 380. All a little high for crs.
My tap is 7.8, GH 5-6, KH 2-3, TDS 220.
i cant seem to get the KH and TDS down. I dont want to do an RO system but was thinking of getting the tap water filter. If I do that would I just mix like half tap with half filtered or whatever will get my levels down?
