Oolite Substrate Question
 

Im upgrading from my current 75 to a custom 140G and am a little confused with what substrate works best with SSB. I'm only planning on running a 1"-1.5" bed. When I set my 75G up I always read that larger substrate such as crushed coral was the way to go for an SSB. Seems now when I read people say that crushed coral harbors all the nitrates. Is fine sand the way to go? I can get a great deal on Caribsea Arag-Alive Bahamas Oolite Substrate. Has anyone used this for there DT ?
Thanks

I would not recommend fine sand in a SSB. The main reason is water flow in your tank. Fine sand will get blown around and you will have to dial back your flow. Every disturbane will kick up a major sand storm.

I would recommend special grade reef sand (or similar).

+1 - i have that crap in my tank and now i have to siphon it out to replace it with special grade :sad: tank is ALWAYS cloudy

So sounds like special grade is the way to go phi delt reefer where in London did you get the sand ? Thanks

I used the fine sand only I used about 2" layer of it... at first I had a sand storm that lasted 4-5 days... it settled down and since it has been good / no problems... I used it in a 90G with 800gph sump pump and two Korillas rated at 1200GPH on either end of the tank / Reef style tank

Why shallow sand bed (SSB)? The benefit of moving up to 2 to 3 inches is as follows.

1. The bed will assist in the biological cycle in your tank.
2. The bed will be populated with all kinds of organisms from worms to bacteria that provide food for your corals and small fish in your tank.
3. It looks natural just like the ocean.
4. You get to keep neat things like small wrasse that need a sand bed to sleep in at night.
5. Sand sifting snails and conchs are fun to watch when you drop some food to the bottom of the tank.

If you still want an SSB go with the fine sand. In a few days it settles down as others have suggested.

I have a 12" shallow tank with 3000 gobs of flow total; 4powerheads and a return pump. I only added the final 1050 koralia unit last week after diving my sand a month to gum up and my sump is now full of sand. Probably because my tank is shallow, but you can see the nitrogen pockets already developing. I have about a 2" sandbed. Well that what I started with. Now I have 4" deep areas and some that are 1" or less. Looks more natural but my tank has looked "foggy" for a while.

I got my sugar sand from Eco reefer.

The Carib special grade sea floor will come from exotic reef in east London. It's a new place but u need tO call ahead for they don't have set hrs yet.

I thought about running a 4"+ sandbed but have read alot of horror stories about people having lots of issues. I plan to run about 1.5" bed and continually stir it up so nothing will settle. Save money and time.
