My only experience is with the live sand sold at the LFS
. To be honest, I would like to add about 400 more pounds of sand to my tank, but right now HD
is not carrying it. However, the main reason I havent tried it is because the two guys at the LFS
(who have proven themselves 98% trust worthy over the last 2 years) said that they have see Old castle wreck tanks by causing all kinds of crazy hair algae. To this point, I have been very luck and only had one very minor case of nuisance algae in the last 5 years. I am very reluctant to use Old Castle. Any thoughts or opinions on this?
