I dose my 55g with about 1/2 - 1 cup per day, nannochloris with cell density of 61.4 million/ml.
I dose heavily, for the benefit of pods, crocea, feather dusters, and anything else that wants it.
I recommend starting at about 1/4 cup per day and work your way up from there. I've seen your tank and I think this would work for ya. If you do not have alot of filter feeders that will utililize the phyto and just trying to increase pods, then every other/couple days would suffice.
