Sand in a 90Gal??

Ok, I have read alot of posts on DSB vs non DSB. How much sand should I use in a 90gal, as well as how much of it should be live sand?

 

i have a solid inch or more in mine

 

a inch or less in the tank. if you want a dsb don't put it in your tank make it in the fuge that way when it eventually becomes a detriment you can take it out easily and replace it.

personally i would say 50 lbs is probably enough for me, i like it shallow less problems

only a small portion "should" be live, the rest should be regular, the live will spread.


i quoted should because if you have live rock you could forgo the live sand completely. i mean really how much living stuff survives in a air tight, unheated bag for months. maybe some anerobic bacteria? nothing that uses oxygen is still around

 

Pretty much what my LFS said, just wanted to make sure.. I do have a fuge setup that I incorporated into my sump. Just sand or have a mud base then sand?? My sump is 40gal, the fuge side is 17 1/2" D x 12 3/4 W x 13" H...

 

mud is to expensive for my taste, to really be a viable option. all natural unscented clay kitty litter is the same stuff the mud is made out of just nothing alive in it. personally i would just use sand.

kitty litter is either zeolite or diatomite. which have been used in planted fresh water tanks for years.

 

Sound good, just one question how deep in the fuge

 

if you do mud 3-4 inches(i think)

sand is 6 inches, don't go under or it wont do its job, and there is no benefit to having it deeper

 

Thanks you so much!

 

John I have a 90g with deep sand bed.About 3 or four inches. In my 20g refuge I have only about 1to 2 inches. 1 inch mud 1 inch sand. I used crushed coral and sand in dt I wish I would not have used the crushed coral. It tends to show the dirt where the sand is to fine
to pick it up.
