It's been quite a while since my last post. My soft and LPS corals have been growing rapidly and developed nice colors. Coraline algae has finally started growing and I also stocked up on some SPS corals. That increased my Ca/Alk/Mg demand drastically. I do weekly water changes and thought that...

So I haven't been the best with keeping track of my parameters the past few months, as everything up until now was consistent. I tested my DT water yesterday and my New Salt Water as well. Below were my findings... DT SG 1.026 Ca 425 Mg 975 Alk 6.72 pH 8.27 Temp 77.8 NEw saltwater (power...

Hey guys! Just wondering if it is a bad thing to have elevated magnesium levels? I heard it's pretty good for getting rid of nuisance algae (which I don't have much), but I just wanted to make sure this was acceptable and not toxic. Thanks! All other parameters are great.

Red sea suggested that daily increase of Mg dosing shouldn't exceed 10 ppm. Do you agree? or disagree? if not, what should be the limit? or what is your experience so far?

Hi all, I have had my 29g cube up and running for about 10 months now and everything has been running smoothly and stable. I test regularly for CA, Mg, and the alkalinity. My numbers have been in the following range: ALK: 7-8 KH in dKH/2.50-2.85 meq/L CA: 400-500 ppm Mg: 1270-1290 The ranges...

What is wrong with my water parameters? I started checking my water about a year and a few months ago from around this time. I haven't checked my water in over a year from this time last year. Even when I was testing my water weekly the numbers seemed to be all over. As of today my water...

So I've had my 75 reef up now for a little over 3 months. All of my levels have been good the entire time, except my magnesium seems to be a little low. All of my corals look great, so maybe it's not a big deal, but wanted to see when I should be concerned that it's too low?? Also I have very...
