Is there a swimming pool or spa supply store anywhere near Point Pleasant NJ ?
If so, just buy a bag of pool filter sand. Your shrimps will love it.
They sell PFS in 50 lb. bags for around $10, and you'll have enough to do 2 - 20 gal tanks, or more.
yes but i dont think it will lower my PH, i think its a little high for CRS right?
