is it possible

[rudyr03]

my nitrates are at nearly 20 and i wanna replace my crushed coral for sand if i buy the carib sea sand from my lfs when i go to replace it ...has anyone ever done it all at once or step by step..if so let me know how you did it

I'd do it all at once. And that carib sea stuff...its not the live stuff is it? Just dry sand, right? If it is dry sand, good.... You should be able to just take out the CC and put in the dry sand. Maybe since its that large of a tank you should do it in like....quarters or something, but i'm not totally sure that'd be necessary.

Should help your nitrates by switching...

I've done just that in my 120-gallon reef tank. It was a bit of a hassle to get it done by nothing so bad as to not do it. I did it all at once. I just scooped out as much of the crushed coral using my hands and a regular fish net to get the bulk of it out. The harder part was getting as much of the CC out from under and behind the rockwork as I could. I used a power head with a piece of vinyl hosi on it and also a turkey baster and eventually got most of it out. I didn't get 100% but probably something close to 95% because I have a lot of rockwork in the tank.
