my tank was a salt fish tank i switched it over to a reef tank, 90 gallons 216 watts of t5 refugium super skimmer 50 lbs of live rock just put in four pieces of soft coral. the rocks turned dark brown lights are on for 12 hr a day help first tank please be gentle
lol, you actually took my advice. See? We be helpful here.
Your tank is cycling, and it's normal. After the 7th or 8th week or so, you can start testing for nitrates, and maybe even do a 5 to 10% water change, and all that brown stuff will subside.
about the wolf eel... most fish you may want in your reef are not large aggressive fish, they are small little fish which i am sure are quite tasty looking to an eel. my advise, take the eel out before your infrastructure becomes to complicated. moving rocks is easier than moving rocks and corals.... j.m.o.
Tom, I take pics on manual mode, 125 shutter, lowest f possible, I try not to zoom with the lens, it makes the fstop higher, thus making the pic darker.
