Hi, Chris--I'm sure you'll get lots of great advice from people who are more experienced than I am, but I can offer a few thoughts . . .
First, yay for you for being patient and letting the tank cycle before adding fish--that's hard! How did you cycle it? Damsels are generally hardy fish (why they used to be used for cycling), so the fact that they are dying suggests there's something wrong with the water. Can you test for ammonia, nitrites, and nitrates and post those results? Also, what's the pH and SG
? And how big is the tank? The more info like that you can give, the more help you'll get.
doesn't take much lighting--it will do okay under NO
lights. (I have a piece in my QT
tank--no meds--and it's doing fine under a wimpy little NO
bulb made for a 10-gallon tank. The coralline algae grows slowly, but it is growing and I have feather duster worms and even pods
. I guess that's what they are, at any rate!) Most people here will tell you LR
is the way to go for filtration. If you ever want corals, though, you'll have to upgrade.
My advice would be to hold off on more fish until the problem is nailed down and fixed. It's clear there's a problem, and just putting more fish in isn't going to make it go away.
