I personally feel if you wash the quickcrete very, very well to remove the dirt and impurities it is no different than glass. You are always gonna hear about alage issues with ANY substraight, regardless. More to do with the tank husbandry than the substraight I would venture a bet
. " I hate my sand, it causes alage blooms...., Did I mention I over feed, overstock, use tap water and never clean my skimmer..."
I paid something like $19.99 for a small bag of white agg. sand from petsmart for my nano cause I am just partial to the color and its a algae nightmare most days. The cyano is under control now that the RO is going but the green glass is sometimes 2x a day.
