I am in the process of switching from my bio pellet reactor to vinegar dosing.
The bio pellets work but controlling its strength is questionable if not just very time consuming .You have to wait and see how much what have installed reduces nitrates .. Nothing happens fast in tanks that is good.
Vinnegar dosing , like othe carbon dosing options needs to installed daily if not 2X but the amount and effort needed is so little you could be brain dead and pull it off. I know this for fact !
My 120 with at least 40g in sump will only require 20ml of vinegar daily. I have read a little and plan to experiment with an ATO that will dose the vinegar also as its life in dilution is not as short as vodka. I may only need to dose ATO 2-3 times a week when I fill it up..
Whether you go bio pellets or carbon dosing you need a good skimmer to get ether to work as the bacteria created that eat the nitrates need to be skimmed out or you will get a massive slime accumulation..
Unlike in freshwater where PO4
is used by plants and even dosed , phosphate is a serious problem in marine tanks . It is believed to be the root of almost all algae along with nitrates.
Most forms of carbon dosing do not effect the PO4
like nitrates so other options must be considered . They do reduce PO4
but in a 1:4 ratio or less compared to nitrates so you will need to help the PO4
get out with other efforts.Po4
needs to be very low in compare to nitrates and often get special effort for removal on its own.
I use GFO
in my sump in a reactor for PO 4 removal. Others use lanthanum chloride like carbon dosing to control PO4
