I've been dosing for ~6 months now and I just recently cleaned my sump due to its white solid deposits on the glass that took me a day to scrubbed it off.
Right now I'm using kent salt and it gives me fairly high calcium reading and a low calcium. So I dose my tank with aquavitro (eight.four) a KH
buffer to have 8.5dkh at 450 ppm
calcium. I have my doser set 21 ml/day of the eight.four in my sump where I put my return pump.
How can I stop this solid precipitate? or should I be cleaning my sump every 3 months and scape this white thing?
