ive stood there with my wife for over 40 mins looking at pvc
fittings and she must think im a complete dolt. Sorry but you cant make a good u tube from pvc
fittings, trust me ive tried it and i have a new gray hair from it.
Dont let the hype of southdown make you nuts its just aragonite sand and even the quikrete isnt that bad its just silica and i know plenty of ppl that use silica for years and never had any problems with it. Spend the 40$ for 40 lbs of it (i dont know your size of tank but 40lbs usually works ok if you dont need a 3" dsb
). Start a new trend and use a bare bottom, just cover it with shrooms
and gsp. Make a trend dont follow one
