Hey platax you r not too far from me. I live just south of you on Hwy 27 in Davenport.
While I was at MACNA a few weeks ago I had a chance to speak with Jon from WM about the EB. He did say that the entire amount was recommended. But he also stated that some aquarists had experienced algae blooms when they started with their entire batch.
Some aquarists here like myself have started with less and so far have had no algae blooms but as poolkeeper says you will not know the whole effects of EB product unless you go wth the full batch. Take look at your bioload.
Hey js, I live right off 27 also, by Lake Luisa (hwy 50)!
I will be going up to the full batch slowly because i dont have a choice my only reactor can accomodate only 500 ml untill my new one comes in late next week. I will add 250 additional ml and then again the following week.
