Richard,

Since you are an enthusiastic Aquasoil user, perhaps you can help to clear up some of the questions that I have not been able to get answered.

I believe that Aquasoil is impregnated with nutrients that are released over time. If it is, I'd think that one wouldn't have to dose. But if one still has to dose and, apparently, do EI, then what is AS adding? And isn't the EI water changing removing the stuff that one paid extra to get from AS in the first place?

Perhaps it permits a better flow of nutrients around the roots? But if plants get nutrients mainly from the water column, then what? Maybe insurance?

Could AS be used in a low light, non-CO2 aquarium? If it could, would it require water changes more frequent than monthly, do you think?

Thanks.

Bill
