Low dose erythromycin to get out of ULNS funk?

[Randy Holmes-Farley]

I have an experiment running that tests the notion that the initial presence of a nitrifying bacteria can affect how micro algae develop. I am tracking diatom, dinoflagellate and cyanobacteria growth. The test aquaria are 16 days old but they need to be about 80 days old before we can be confident about the effect. So, news in February.

Sounds great!

Using EM to treat for cyano has often led to more dinos for many people.

The key is the real estate. Dinos thrive when nothing else is around to populate the area - they move in and settle faster.

It is likely that the dinos are the only only filter that you need and that the AOB are already cut back by competition. As mentioned before, EM doesn't really kill AOB or NOB.

You can growth limit dinos by raise nitrate really high (poison them) or make their real estate disappear. Those are the two choices that seem to work.
