The tank is going through the algae phase which I expected at this point. I'm getting a lot of diatoms which doesn't worry me even though they're unsightly. I'm also getting another algae that I cannot identify. I've looked at it under the microscope, and it doesn't match any of the algae I can find so far. It's actually quiet beautiful, and if it wasn't so aggressive, I'd love to keep it.
The algae is very bright green and very short. Under the microscope, it does not appear to grow in lengths, but in bunches (meaning, it doesn't grow like a stem, but more like a crypt or sword). The "leaves" are very short, pointed at the bottom and top, and fat in the middle (like a pointed banana). If it wasn't so bright green, I'd think it was another type of diatom, but its cellular structure and color is not the same as a diatom. The overall appearance is like a short bright green BBA. It blows in the current very pretty.
So far, it does not match BBA, green brush algae, any form of hair or filamentous algae, or any algae I can find on the internet. I've tried to identify it through all kinds of ways, but I'm stumped.
However, as nice as it looks, it's too aggressive. This algae definitely likes light as it is growing rapidly on everything closest to the lights. It's on the wood and leaves of the taller plants. It's completely coating whatever it's on which, if allowed to continue, would block photosynthesis. So I've had no choice but to treat the tank.
Yesterday, I hit the tank with 4ml per gallon of H2O2 for a total of 300ml. I spot treated as much of the algae as I could. I also hit the areas with diatoms to see if I could get rid of any of them while I was at it. Then I let that sit for 15 minutes with no filters and no lights. Then I turned on the filters and let them run for another 15 minutes while the lights remained off. After that, I turned on the lights. About 7 hours later, I did my weekly 50% water change.
The tank bubbled like crazy which is what I expected. Today, the water is a bit hazy from all the dead algae, but the fish and inverts are doing fine (the pelvicachromis are still doing their mating dances and all). The plants already look better without so much algae covering them. Interestingly, it looks like the treatment may have killed the diatoms as they aren't as dark as before which makes the whole tank look better. I'll know by next week.
I'll be doing extra water changes this week to keep up with the dead algae, but so far, so good. I will probably need to do one more H2O2 treatment to catch any bad spots I missed before, but that should be it. Once I get the tank passed this phase, the tank should do great.
