Figured out what was wrong with my PH readings. Doh. Controller was calibrated incorrectly. I went out at lunch and got some 7.0 calibration fluid, the meter was set .6 above that. I've calibrated PH probes before, and never screwed up like that. At least now I know.
Things are growing, so that's pretty exciting. In addition to plants, however, snails and some algae are growing. Small snails that are easy to squish, but I'm a bit worried that I won't be squishing enough, and I'll get 'overrun'. And not a lot of algae, but I've got some green hair algae (that's my newbie identification, wouldn't be surprised if it's wrong
) on my ludwigia repens:
It's on other stems of the plant, in addition to what's circled in red above. Quite a bit of the plant has it. Anything I should do about the algae? Throw out the plant? I'd hate to, it's starting to get some good growth. Just leave things as they are, and hope I've got the conditions right so the algea will starve? It's not starving so far, as you can see!
