ok whoa!! just finished reading your journal. man, you have been on quite the journey with the tank. I showed my wife the youtube video you took and said "see, that's a cool little tank out there on the rock. yeah?" she agreed.
But man oh man did the algae monster come looking for you!! But first off, let me say, I think your tank looks awesome right now. It looks like it is starting to bounce back in a major way but it may be too late if it is starting to get under your skin. I think by January it should be pretty lush. The mini m's are hard because it is such a small amount of water. And when you start tinkering with it to address a problem that arises like bga, aquarists like ourselves feel like we are chasing after the wind. I forget who wrote the comment in this thread, but somebody had mentioned that it may be fortuitous to simplify. Once you start throwing erythromycin into the water the road can get quite bumpy.
Did you say that you measured the PAR from this light? What is your photoperiod btw? I've only had bga issues once in a 29g more than 10 years ago....whoa. I remember I had manually removed it and increased the water flow which seemed to help. How often do you clean your filter? Once a month? Do you change the filter floss media for the 2211 near the propeller? I change mine every three weeks or so and replace it with batting. It always gets way dirtier than I imagined and has a dramatic effect on the water flow.
What's also hard with these small tanks is that when we address a problem or change a particular aspect pertaining to the water quality, we want to see results immediately. sometimes it takes weeks before we see results and take notice of how our plants respond. but if the result doesn't formulate sooner, we go at it harder. I'm speaking solely for myself and my experiences here but I think you may be able to glean something out of this diatribe I'm having.
Not sure what your tank regiment is like, but I think you should rinse your filter media, switch out the filter floss, raise the light on your tank a few inches higher, reduce your photo period to 6 hours and manually remove any algae you see along the way. bga is a bacterial problem, which your most aware of, but maybe these little adjustments will calm the algae storm. I've read how cyanobacteria thrives off of the smallest available nutrients, but don't let that keep you from dosing. and don't forget the co2. keep it cranking if you don't have any fauna in there. This all should buy you some time and maybe make the tank more manageable. And those plants will grow. they will most definitely grow.
clean filter, ample light (you don't need high light intensity for those plants), more than adequate co2, and ferts and you will be ok.
Not sure what you will need to do when you go away for your trip that you mentioned. You could possible raise the light even higher when you are gone and keep the photoperiod to 6 hours and your nutrient co2 demand will be more manageable in your absence. just some thoughts for the surfing aquarist out on the rock.
