I'm going to change out the crushed coral for sand in my 75g tank. I'm also trying to add some live rock in there, but this question is about the sand. I am SO over the cc.
I read that I can do it gradually by taking some of the cc out and putting sand in, then taking out more cc and putting in more sand, etc. I currently only have 30 lb of sand and I'd like to get it in the tank and then add more later.
Is this okay to do? I plan on starting on one side of the tank and putting my lone little chunk of live rock on the sand. Then I will move to the next section when I get more sand and perhaps more live rock. I will try to add some live sand or grunge once the substrate is done being switched out. Is any of this going to cause problems for my tank inhabitants? I know a large amount of LR
needs to be cured first but how about the 'dead' sand?
Also, what's the best/easiest way to rinse the sand? This stuff is super fine.
We've had this tank for a fairly long time but I haven't done a lot of upgrading on it. I'm fighting green hair algae now (old tank syndrome, I'm guessing) and want to get better filtration through the sand and LR
to hopefully get things back on an even keel.
Any help/advice/suggestions/cautions are greatly appreciated! I don't want my 'improvements' to wind up causing worse issues.
