[QUOTE=zonkkie;9765778]Saw your post on your very impressive big tank! Amazing! Ok - so the more economical option is still baking soda and epson salt. Do you do anything to prevent the sand going down to your sump?
yup..so far no problem witj baking soda and epson salt..i didnt really try to block sands from going down into sump.as the overflow is on the top surface..seldom will have sand being filtered down..but overtime sure will have abit of find sands in sump..but its fine with mi.
