I am interested to install a sulphur denitrator for my fish only marine 400liter tank. Apart from sulphur in the reactor do i need to put other media to increase the ph and alkalinity or can i just dose alkalinity liquid? I am trying to find out if i can put only sulphur in the reactor and not split the reactor with 2 different media or install a seperator reactor after the denitrator.
I cannot get nitrate below 45ppm even though i use nopox, and oversized skimmer, and phosphate varies between 0.04 to 0.10 sometimes.
Also what pump do i need to attached to the denitrator if it will be staying outside the sump in order to compensate for pump head height. I dont have much space for cheato in the sump so ideally i set up something outside the sump , to lower the nitrates.
I understand nitrates in 40ppm range is ok for fish only but i prefer to lower them to 0 and then dose nitrate from doser if needed. I want to be able to add some corals later as well and like this the system will be ready once i decide.
Tank is 1 year old and not very overstocked at the moment but i feed quite a bit.
Thanks
