live sand, sugar fine oolite and crushed coral, reduced

[msmith619]

So, for $120 I can get it all? Both the live sand and the crushed coral? My new tank is being delivered tonight, great timing. It is a standard 125 (72 x 18 x 24) with a standard 48" 55 gallon sump.
Would it be too much to just use it all? If not too much, I will take it. Give me a a day or two to get my new tank filled with water then I am good to go.

Hi,

What are the length and width of each tank? Are you considering the fine sand or the crushed coral? Or, sand above and crushed coral in the sump?

The conventional wisedom of day suggests you use either just inch depth or 3 1/2 inches or more. Don't use a depth between 1 and 3 1/2 inches. I'm personally not a fan of DSBs any more. But without it, you need another method of getting nitrates out of your system, as you probably know. I would go with 1 inch in the display, and maybe 4 inches in part of your sump.

If your 120 is 24 * 60, you need 1440 cubic inches for 1 inch depth.
If your 55 is 48 * 12, you need 576 cubic inchesfor 1 inch depth (if you cover the whole bottom).

I have 2500 cubic inches sand and 1155 cubic inches crushed coral.

You could go with sand in the display and crushed coral in the sump. Different grain sizes encourage different types of critters.

If you want, I can sell you just what you need at the prorated price.
