I'm about to do a big WC and start the 4-5 day dosing with erythromycin. The BGA/Cyanobacteria keeps returning even after I remove it during water changes. I have been careful to give the WC bucket a rinse in hot water before using it to refill the tank. It's been lurking in the tank at low level for a while. Just tired of looking at it. It is not on the plants, just the substrate and walls.
I will also be making an adjustment to the lighting schedule. Even though the DCs are lime green most of the time, the full intensity of both Finnex fixtures on at the same time (right now 3 hours) may be too much. Going to try to reduce the lighting and see if this helps with the BBA on the star repens and curled leaves on the AR mini. Downoi is looking a little meh but I recently replanted it. The rest of the plants are doing fine. I am using the standard PPS-Pro dose of 1 mL per 10 gallons. I think I will have the FugeRay turn off an hour early and the planted+ turn on an hour later. This will result on only a one overlap.
Obligatory FTS. Happy Friday everyone!
