hey im switching my pea gravel to black tahitan moon sand, ad im wondering how much ill need.
footprint of the tank is 48"x26", how much sand (in lbs or kilos i dont care) will i need, the tank will be planted, so i will need it a bit deep, i dont know how deep though.

I figure one to two pounds of sand per gallon for around two inch depth. Deeper sand beds can result in sulfide gases forming underneath if sand is not stirred every now and then. Some say that these gases interact almost immediately with oxygen in the water and are harmless. I have found that if sand bed is two inches or less,,there is no problem with the afore mentioned hydrogen sulfide (I think) forming.
Have also been involved in discussions with regards to Tahitian Moon Sand and it's possible detrimental effects on soft bellied fish such as plecos,loaches,corys,and other catfish. Product is said to be a by-product of glass production and though fine grained,is quite sharp .
Opinions vary.
