Hi - I have a few questions and was hoping someone could help me.
Last week I bought 40lbs of base rock for my 60 gallon SW
/reef tank. Today, I bought 40lbs of Fiji (cured) live rock and 4lbs of Bali (uncured) live rock. I was curious about uncured rock but didn't want to make a huge investment in it so I picked up a decent sized chunk of it for fun. Since this is a brand new tank, I put all the rock in the display tank and some rubble in the fuge. I plan on doing a water test in 3 or 4 days to see what the levels are. I expect to add more LR
down the road.
Anyway, I ID'd what looks like a tiny feather duster extending from a piece of LR
. I was pretty excited and went online to read up on them and now I feel like it is going to die. I don't see how the hostile swinging conditions of the tank and lack of food will allow it to live. But I really want it to live. Give it to me straight - can I suppliment it's diet somehow or should I cut my losses now and expect that it will die and move on?
Also, while I was lost in thought, watching this thing, I saw a long thread like black worm float by. It landed on a rock and began crawling across the surface of the rock and disappeared into a crevice. Of course I thought bristle worm because anytime I search out info on hitchhikers, bristle worm is one of the first hits. But I didn't see any bristles. It looked like a black thread that was about 1.5" long. Any ideas?
And - How much water evaporation should I expect to see on a weekly basis? I'm adding water to the fuge every other day. I don't see any leaks. Can that much water really be evaporating?
Finally - I'm not sure how full the refugium/sump should be. Right now it's half full. That isn't deep enough to put equipment in. But if there is a power outage, I would think I would need to leave space available for backflow? Should I kill the power for a few minutes to guage this? What I have is 24"L x 10"W x 12"H ACRYLIC sump for 40-65 gallon tank.
