crushed coral
 

After recent discussions with Steve (Thanks Steve), I think i'm going to use crushed coral as a sand bed and hide pod piles in the rocks for bugs to grow. I'm doing this so I can increase the flow in my tank without blowing sand around anywhere. Can anyone think of any disadvantages to using crushed coral as a sandbed in your tank?

depending on the size of it ...

Re: crushed coral
 

Its a good substrate for smaller tanks and can certainly handle more flow, as long as you can easily siphon clean the gravel bed, then the detritus{ thus the phosphate }, can be kept to a minimum.

However if its like my friends 180 or my 225, both in a wall, with back access only, then it can be a PITA. I had to eventually remove mine and we just did the 180 last weekend. Both were clogged full of detritus and fueling algae growth.

OK just got to make something clear, my exact suggestion was for a bare bottom no sand bed at all, but if you need something in there for looks until the coralline has set in, then go with a large crushed coral (almost like rubble rock) now to keep phosphates under control the theory is to have massive flow to keep food suspended and to skim heavily to remove uneaten food before it can rot. the return set up i also suggested was to have the return pump disperse the water from under the rocks to prevent a build up of detritus and to aid in keeping the stuff suspended where corals ect. can get it better and to allow for the skimmer to be able to remove it.

Just wanted to give a few more details on the theory behind my recommendation and how it works. :mrgreen:

Sorry Steve, I should have been more clear. I like the idea of not having a sand bed but I prefer the look of a sand bed of some kind.

I have around 80-100lbs of used crush coral that can be wash for trade or sale if you don't have any
