Finally set up my first SW tank - YAY!!!

Even though I did a lot of reading and looked around various LFS asking questions, I had a little misconception that may now cause me a little snag (not sure). I wanted some fish in my tank and not fully understanding the LFS person's question of "reef or swim" tank (thought reef meant corals only), responded "swim" tank. LFS person then directed me to put crushed coral/aragonite as substrate choice. I questioned as to using live sand and was blatantly told no. Now I'm finding out a sand bottom would have been more desireable. Is there any way to work with this situation or am I going to have to pull out all the CC and start over with LS in order to create a good environment for some inverts & corals that like sandy bottoms? Are there inverts and corals that do well with the substrate (not real coarse - guessing 4mm mixed with up to 10mm) I have? Ideally, I would like a tank that has the abililty to provide some reef tank attributes with enough room to have a few nice sized fish too (sort of a 50/50 reef/swim tank). Suggestions??? :thud:

Any help/thoughts/advice is greatly appreciated. Thanx.

This is my setup so far

120g tank - started about 7 wks ago with unseeded LR and cycling nicely
70# LR
100# CC/Aragonite
SeaClone 100
Bio Sump Filter
Rio 8HF Powerhead
1 Blue Devil
1 Green Chromis
1 Yellow Damsel
6 Turbo's
1 Hermit (biggie size)
 
lower welcome to A.C.!!! I'm afraid you have had some bad advise from your lfs. If you keep the c.c. substrate you may have real issues keeping more sensative inverts alive , sps, lps and even some of the softies. You will have nitrate issues down the road no matter how much you vaccume and if you want inverts I'd remove it now before you're tank is really up and running," :( sorry" The nitrate issues will bother almost any corals it won't matter if they are on the bottom or not. Yes, there are some chemical controls you could use but, I would seriously advise against them for use on a long term basis. Also damnsels are a pain in the umh, ah nose and i'd get rid of them before you added sesil inverts etc they often times end up being $100 fish from all the stuf they eat/kill
Sorry
 
Thanx for the input & link Pablo, it is well appreciated & duly noted.

Max - Welcome back at Ya!! I hear ya on the sales BS at the LFS :rant2: and also on the change now B4 future headaches thing :sad

BTW - the damsels satisfied a couple things (helping cycle, low $ sacrificial in the event of water problems or my learning/mistake curve, and ok I admit I was impatient to see something in the tank :huh: )
 
The problem comes with a fish cycle is the bacteria that break down ammonia and nitrite only multiply to the amount of ammonia being produced. So with a fish for the cycle, the aerobic bacteria will only multiply to a large enough amount to handle the ammonia produced by that 1 fish. This is why fishless cyclse are recamended.
