my system is coming up to it's 2 year birthday. A month or so back I added my first corals; a rock with two types of mushrooms. The day after adding them to the system they were in FULL bloom, better than they looked in the LFS
. About a week later I noticed them splitting and multiplying like wild fire and still in full bloom. Things looked great up intil about a week ago when I did the first water change since I got them. Ever since then the mushrooms have been very flacid. They hardly expand at all when the lights come on. Here's the readings:
but I don't have a Mg
test kit. all of my other parameters look spot on and don't really fluctuate (other than SG
as don't yet have an autotop off)
The water change was 5 gallons (on a 55 tank) with CoraLife salt mix. I've heard this can be a touch and go mix but the new mix looked good on what I have test kits for. In the whole skeem of things, how important is Mg
to a healthy reef system? Are they more important to certain types of hard/soft corals?
