It’s been four weeks since the re-do. Conditions are mostly good, although, I found a few small areas of algae – primarily on the HM. I think I planted it too densely at the start. It came potted and I only broke it down into 5 or 6 clumps. Consquently, there were some really thick areas not exposed to light. So… (sigh) I took it all out today and pulled it apart stem by stem and binned the stuff with algae. I replanted the same area with single stems. I think it will fill in nicely. It’s also easier for the otos to get at it.
I have two clumps of the Rotala walichii. The clump on the middle-right side is doing really well. But the clump on the front-left side has been struggling. It grows slower than the other clump and it’s starting to pick up a little bit of algae on the original part of the stems. I pulled it out and removed any stems with algae and moved the rest to the center area of the tank.
I added a couple of small swords – although, I haven’t ID’d them yet. The new leaves are red with dark red spots and then they turn green with red spots as they mature. (Echinodorus ozelot?)
I also added a couple of sags, two anubias and a java fern. All of the additions came out of the 55 gallon tank.
I changed one of the 65 watt bulbs in the power compact fixture. Definitely makes a difference. The light is much whiter on the left side of the tank now. You can see the difference when you look at the bulbs. (Probably not such a good idea to stare at 130 watts of light for too long B) ) Anyway, the older bulb has a brown-ish cast to it while the new bulb is very white.
I think I am going to change the CO2 tank today. The current tank is nearly empty and I’m afraid it will run out when I’m at work next week. Can only imagine what an entire day of no CO2 and high light will do.
Before the water change, these were the stats:
pH 6.4
KH 3-4
Nitrate 10ppm
Phosphate 0.50ppm
I dosed NPK twice this week. Just started adding Flourish on the off days. Generally speaking, does the Flourish provide enough iron so that I shouldn’t have to separately dose iron, too?
Also, based on the pH and KH, the level of CO2 is between 36-48ppm. Is that ok? The fish look fine and are not gasping for air.
