not pro, but let me chirp in with my personal views.
Peter ever explained to me. recalled that AZ NO3 & Biodigest compliments each other.
So yeah, can be used together. Will let Peter jump in more on this later....
AZ NO3 is good but tedious. long term wise, not sure if it is viable.
biodigest is bacteria.
bioclean = biodigest + biotim (trace elements)
I like prodibio products. but feels that diligient husbandry can make the tank looks cleaner rather lean on bioclean to make your tank looks clean.
