Yep, BGA and green hair algae all over the place. The BGA is covering most of my glosso patch/plant leaves and the hair algae (at least thats what I think it is--looks like long, individual strands of hair) is mixed in with my xmas moss. Up until this point, I really had no problem with algae--minor booms now and then, but nothing this bad.
20g paludarium with about 6" water (around 12 gallons total). PH around 7.8. Lots of surface agitation. 65 watt PC lighting (on 12 hours). Eco-complete substrate. Lots of hygros, ludwigia repens, java moss, xmas moss, glosso, bacoba carolinia--most of the ludwigia and bacoba is now growing emersed. I just added some more bacoba from a nearby fish store.
Dose 1 mL flourish excel daily. 0.5 mL flourish nitrate and phosphate every three days. Dose 2 mL flourish potassium twice a week. Lightly dose trace on water changes and hardly ever dose iron. A few (I took the conservative approach) Jobes plant sticks (can't remember the proportions--something like 15-5-5) in substrate near plants that are growing emersed and the glosso patch.
Other info to consider:
1) The temperature just went up a bit in the tank (warmer weather around here)--it went from around 65 to 75 over the course of a week. I'll try out my chiller if it gets any warmer.
2) Many of the plants were recently cut back/replanted about a week and a half ago.
3) Many of the stem plants are now growing slightly emersed. Do these plants feed more through the roots?
4) Only four white cloud minnows and one small hillstream loach in the tank--is this load too light? Should I be adding some kind of fert that is normally supplied by a decent load of fish?
5) The plants don't seem to be growing very well, but nutrients are being used up somewhere.
6) Perform 10% water change daily. I do not vacuum the substrate and I definitely don't overfeed my fish. Also, I do not change the filter pads very often. They're pretty grungey, but they still do their job.
7) The tank is only about 2 months old.
Any advice would be great. I'm currently monitoring tank nutrient levels to get a better idea on how much is being used up per day.
