My question is has anybody experienced a huge drop in magnesium consumption in my tank. My auto doser used to dose 40ml of mag a day, i checked leveled and they increased from 1375 to 1470. I stopped dosing for 2 days and it was still at 1470. I now dose 5 ml a day to keep it stable. Does anyone know why this is happening? Coraline algae is almost non existent as well due to my urchin.

I have similar issue so following along. I have never once dosed mag in almost 2 years and levels have always been around 1450. I always figured it was just my salt that might be high in mag. What salt do you use?

Thank for the compliment! I use natural seawater I have been buying from my LFS for the past 2 years.

At first I thought it might be the salt mix but I tested the seawater and parameters were in normal range. Has anybody else run into this before?

Zevoit is the shitznit, I've got to start using it. Every tank I see that it is being used in rocks! Yours Included.

You definitely need to do your research, but they work wonders! Thank you for the kind words.
