Coralline will suck up butt loads of alkalinity (and calcium to match). Most of my clients' tanks need alkalinity supplementation and most of them are only lightly stocked with corals.

It really does and I'll be the first to say it sucks hard lol I would like not to dose but the option simply isn't there .........i have to dose to kerp the coraline alive lol now from what the Internet and forms tell me a water change should be all I need but it's not and alot of people find them selves in a similar boat it's not just coraline there are other sinks but coralines am effects are quite noticeable in comparison
