hey everyone! my name is seymour, and i happened to stumble across this website and i figured maybe you guys can help me out with some problems i am having with my first reef tank. this might be too long of an explanation so get ready lol
i have a 37 gallon tank with a 2X65 compact flourescent light (one white light, one actinic). the tank has been set up about 3 months, and has had coral in it for about 2 months.
i've got about 50 lbs of "arag alive" sand, and i have a lot of live rock but i am not sure exactly how much live rock i have.
my coral inventory consists of 4 different corals: green button polyps, some type of blue mushrooms, a green devil's hand coral, and a rather large toadstool coral
i did my research to a certain extent before taking the plunge into the reef setup, only to find out (only 90% sure of this being true) that all those supplements (i.e. calcium, strontium, iodide, trace elements, magnesium, etc) are completely useless and actually cause more harm than good on a reef tank.
so i first got my green button polyps, and they opened up really wide and were looking very well for the first 2 months that they were in there. about a month ago i picked up some more coral, a green devil's hand leather coral and some sort of blue mushrooms. all was going well and all looked pretty good for quite some time.
i then picked up another coral, a really good sized toadstool coral. i did a decent sized water change (about 6 gallons) the day that i added it. after that point, everything continued looking pretty good for the next few days, until about a week ago i noticed my button polyps were closed up, and my devil's hand is now slumped over and does not look nearly as good as when i first added it.
and it's pretty much been that way for a little over a week now. there were a couple days that my toadstool slumped over too, but now it's looking spectacular, though i wish i could say the same for the rest of my coral.
EDIT: ALSO: my kH
is 10 and i have been keeping it buffered with baking soda.
long explanation i know haha, sorry! surely i have to be doing something wrong, any thoughts?
