Sheldon,
i dose indeed simple vinegar into the sytem,around 20 ml in the evening,why
put a drop into your mouth and see what happens,it,s the same whit corals,after dosing the vinegar you get good polip extension and the corals are ready to take some extra food.
In a lot off bottles you can buy into your shop you easely can detect the vinegar or related products as an appetizer.
The carbon is a small but welcome extra.
Phosphate is undetectable in the system here,i think for my example there are a lot of reasons,very good coral grow(whats very good,in my old two meter tank at least 1000 good frags a year)
When they are growing they absorb no3 and po4 and are helping too get a system in balance.
I always believed that a tank runs better and better if it contains as much as corals you can put into that tank.
When i have a lot off frags into the cellar they absorb a lot off all kinds off stuff and so they are a part off keeping my tank in balance,in these tanks there is also sand so in the end i get a lot off bacterial substrate too.
After some time you know your system by watching your corals so i know when i can give something extra for my fish or corals.
I talkt a lot whit some people who know something more as the most people do about bacterial live and in their eyes a full fragtank whit sand in it is very good to keep these values very low and in the end it pays better as algea.
I hope this answer gives you an answer on your questions:wave:QUOTE=Scej12;19007033]Hey Luc - I thought I read somewhere that you are dosing ethanol or vinegar (some carbon dosing), but hope I'm not mixing up your tank with someone else's. Is that correct?? Also, what would you say is your strategy for maintaining trace levels of phosphate, I noticed you feed quite heavily to keep your angels satisfied, and you've also mentioned that gfo is only rarely needed.... please tell us your secret formula for keeping your nutrients low. Thanks.
