Anyone not dosing? Just waterchanges?

[Myka]

I have a few client tanks that don't need dosing but they only have softies and maybe one or two LPS. Anything with SPS (especially birdnest and Monti caps which grow stupid fast ) amd more than a couple LPS need dosing. Also, some tanks grow crazy amounts of coralline which sucks up calcium and alkalinity like nobody's business. I find many Euphyllia coral, Acans and Blastis are sensitive to low alkalinity and get brown jelly disease - among others.
