substrate

i have set up filter system with a 4ft sump containing a 150mm layer of calcium carbonate. as my LFS told me. for my 5ft x 2ft x 2.5ft tank. also included is a venturi protien skimmer with its outlet conected to a box containing bioballls. i had a bag of calcium carbonate left over and i thought it would alright (and look good) as the substrate in my tank would this be alright?

To Reef Central

The calcium cabonate won't cause any harm, but coarser substrates tend to accumulate detritus and become a maintenance nuisance, IME. I stick with a fine grain of sand now.

The finer grained sand (oolitic) gets my vote hands down

I can agree that it's generally best not to use a coarse substrate.

I vacuumed my substrate, but when I took it out to switch to sand, there was still a lot of nasty stuff beneath it.

I started with crushed coral and switched to sand. I sand is much easier maintenance and has led to a lower nitrate level.
