Thank you appreciate your answer. So i guess i can dump a bag of sulphur beads in the sump. Lot of people are afraid of hydrogen sulphide as it is toxic/flammable. I read somewhere that probioctic bacteria do reduce the toxic of HS. What is the worst thing can happen if somebody reactor creating the foul smell? I havent heard someone had incident regarding this HS for this hobby yet.
HS produced in a ( sulfur) denitrator should not become a problem. In such reactors the flow is limited. The effluent always has to be aerated.
In the case of problems with H2S, HS is produced due to mismanagement and not because elemental sulfur is used.
As explained, some HS is produced everywhere in the tank, but it is used up before being released as H2S, which you can smell.
One must not add any bacteria, they only add competition if they add anything. But you will sponsor the dealer. In an established aquarium the bacteria needed, such as T.d., are present everywhere. Of coarse, if one has the availability of conditioned BADES rolls, conditioning a new tank will take less a week.
Such filter columns can be made without adding sulfur, filling the rolls with a substrate suitable for the purpose. The main purpose of BADES colums is supporting the carrying capacity, not the denitrification capacity which adds nothing to the carying capacity, exempt preventing future growth, limiting the bio-load.
Exporting too much nitrate has side effects, as does removing too much phosphate or too much from any essential nutrient.
I try to keep the measurable nutrient reserve in such a balance nitrogen, besides organic carbon, is the main growth limiting factor and not phosphate.
I do NOT advise just to dump a bag of sulfur beads into the sump, one has to follow the basic rules for good results. if not one may expect the normal side effects.
Sulfur beads will be broken down into sulfur particles, that is why we use filter cloth for making the columns, but this is not the only reason, as
explained in the article.
