work out a baseline adverage is 1/2 tspoon per 100gallon (uk gallons, so yours would be different) then once you see a reduction in perams half what your doing,the idea being to kick start it into work then just run it as a support feed to the tank, were as vodka you pushed up until your at the point of bloom and just halfed again and maintained that level, if your nervouse of doing this the easy way is dont do it or half what your maths tell you to start with and run there, it will take longer but do the same thing, The whole point of me putting my post upwas to show that it does go wrong, granted this was by nothing more than a accident and it just so happened it was a carbon based accident, but it was posted as no one ever puts up what happens when they naff up,i do ive only been doing it ten years so i am no docterate or hold no degrees in marinekeeping nor will i ever lay claims to doing so thats mother natures job,all we do is pinch a bit and strive to do the best we can, with what we have at hand, for these that say dont put this,that and the other in a tank its not ment to be there, well just one thing for you to remember,neither is all the crap we have and will sink, spill and dump in the seas, its just a case of volume thats dilutes it down
