I would have done a hell of a lot of research first.
OK, here's the problem:
I started a 29 gal
. tank with the intent on doing a freshwater tank. But I got ambitious and switched over to a SW
tank shortly after filling the tank with water.
I was using a trickle filter (purchased for the fw
tank) and started to cycle with damsels. Had I know that I could have cycled fishless I probably would have done so but anyway...
After two and a half weeks of running it this way and adding some LR
, I bought a wet/dry and switched over. I took the bio wheel out of the original filter and put it below the bio balls on the new w/d.
So I've had the new filter up and running for about 2 weeks now. There are 5 damsels in the tank, a few snails/hermit crabs and about 25 lbs. of LR
with a 2 1/2" sand bed (live sand with crushed coral stuff). My readings have been wierd. Right now I'm still showing .25 ammonia and a high nitrite spike and my nitrates are also moderately high. Recently I've noticed a green/brown/rust powder on the tops of the LR
and some of the sand.
Like I said, if I'd planned to do a SW
tank from the get go, there wouldn't be anything but LR
, sand, water a few dead shrimp in the tank right now with the wet/dry running from the start. The tank would also be larger as I'm learning that I'm limited in the fish I'd like to stock the tank with. But since I took the bonehead route here, any help is greatly appreciated. What do you make of where I am in the cycle. I've done a few 15% water changes which I know probably have extended the time until the tank is cycled but I felt bad for the damsels.
And what is the brown algae? I don't think I have any sand that would have silicates in it...
