Crushed Coral Swap for DSB

idrum · 05-31-2001, 07:18 AM

Gonna swap crushed coral for DSB - still debating wether to swap out over time or do a one time.

If I remove my Crushed Coral and add the Southdown with the live sand, will I lost biological filtration?

Also, I have 2 fish (yellow tang, flame wrasse), a few brittle stars and a bunch of critters. If I add the sand and a detritivore kit from Inland - will the DSB have time to seed with the fish and critter or will they plow through all the life before it has time to establish and multiply?

LASTLY - how much sand to I need? The tank is a 72g AGA Bowfront - 48x18 - if the sandbed is 4-6" deep, how much sand should I buy? What can I use if I cant find Southdown? How much live sand?

Idrum, first things first. How much live rock do you have?? Do you have corals or anemones?? I would pull the fish and critters and put them in a seperate tank or container. For the HD sand for a 5" deep sand bed you are looking at about 225 lbs. of sand. As far as the fish eating your detritivore kit, I would start a refugium to get the population established. (If you don't have one already)If there is a way you can give the sand bed a couple of months to get established without fish in the tank that would be the best way to go.

Good Luck,
Sker

Idrum,

Check out this thread, Dr. Ron talks about the DSB conversion process.
