Fert dosing for DIY CO2?

Ok I've started down the path to the dark side. I've just implemented DIY CO2 via yeasty beasties. The bubble count is starting to pick up. 1bps

Now the tricky part (at least for me) is to know how much ferts to dose. I'm not planing on a full on EI regime. Only 10-15 ppm CO2 levels. I just want to enhance my plant growth, not max it out.

I have two individual T5HO lamps w/reflectors. 6500 K, 12hr photo period with 3hr burst overlap. This is most likely too much light, I'll cut back on day length and burst period as needed.

Tank is my 36"x12"x24" 40gal tall. Lights are 22" from substrate. Plants are mostly crypts for now. More plants to be added later. I've got 65 small to medium sized fish.

Thanx for looking

Steve

Never argue with a fool. Onlookers often can't tell the difference.
Growing older is mandatory, growing up is optional.
My advice is free and worth every penny.

OK so I finally figured out how to get 'the chopstick' diffuser to work. You're not supposed to put the whole bamboo chopstick in the tank LOL. Just stuff it as far in the tube as possible and cut off all but a 1/4" stub. Works great compared to an air stone. Bubbles fly out of the end and quickly rise about 12" and then shrink to almost mist size and slow way down and drift around on the currents. That's a good sign that the CO2 is being efficiently dissolved. Don't need to inject the stream into the pump intake and possibly chew on the impeller. Another benny is that my off the 7.6 scale pH is now 6.6. I must have added half the 'lower pH adjusting solution' in the bottle to no avail. Fish look and act great. Need some ferts for dosing now. I'm going with dry ferts & some decent substrate tabs.

I'll do a reduced EI method. I'm not keen on weekly 50% water changes using buckets. I'm really liking Bobs Tropical plants for dry ferts.

For substrate root tabs I don't want the ones that look like Osmocoat pellets in gel caps. I want the ones that look like peat tablets. I don't want those little balls floating around after they get loose. Any good bang for the buck suggestions?

I suppose I'll do some more research on making fert cubes myself.

OK after 2 weeks my CO2 fermenter dropped to 1/4 bps. So it went from 1 to 1/2 to 1/4 over the course of 2 weeks. The new mix is 2.5 cups of sugar + 1 tsp of baking soda + 1 tsp bakers yeast into 3+L. By the smell and taste of the magic juice, the limiting factor was too much ethanol, not a lack of sugar. I'll try wine yeast next batch to see if I can push the envelope some more. I'm also getting a second jug started in a week to help smooth out the production rates from week to week.

I have some Osmocote Plus for my substrate and I'm just dosing a modest amount of liquid ferts. Mostly K + micro. I'm letting the fish supply the N-P portion for now.
