I should have kept up with this better, as I fought a lot of algae for many months.
My plants did really well and grew really well for about 6-8 weeks, then they all stopped growing, and algae took over. Then the plants actually started shrinking, and some died. I thought maybe it was the ferts I was using, so I quit that. I tried buying more plants, nope, that didn't help either.
Finally I got it figured out after like 9 months. (I might have sooner, but I had my second baby in Feb, so didn't have much time to think about my tanks.)
I had gotten a hang on the back Aquaclear filter, and I often let the water level fall below the output level, and the results apparently it was letting CO2 outgas, because I unplugged it and withen 2 weeks my plants looked way better, and the algae was going away! I added a couple Siamese Algae eaters too, and that helped the acutal plants I think.
I was just turning that filter on after a water change, but now I am leaving it on and being more diligent about topping off the evaporated water.
I also moved some fish around. I put the catfish back into the 20 (yes I know it is too small, but he lived there for 8 years, and has a nice hidey hole in the 20 gallon tank.)
Last week two of my Keyhole cichlids paired up and laid some eggs for the first time! Of course they ate them after 2 days, but I had wanted a pair and got them. I took the other two Keyholes out and put them in the 20 gallon with my cat.
Oh, and all the livebearers I had in the 20 died, so it was sitting empty before I put Waldo the cat in there.
I bought 2 angel fish about 6 months or so ago, and the 2 SAEs.
So in my 55 gallon
Fish:
2 angels
2 keyhole cichlids
1 golden gourami
2 SAEs
1 clown pleco
I am planning on adding some tetras of some sort and some cories.
Plants:
Vals
crypts
Java ferns
tiny bit of java moss
I just ordered a new canister filter for this, as the two filters I have are just not cutting it.
I am getting a Eheim 2217.
20 gallon
fish:
Raphael cat
2 keyhole cichlids (I think they might be a male and female too, so maybe I will get a second pair!)
6 gallon
3 female bettas (the same ones)
Here is my 55 a few days ago. I changed things around a bit last night. Need to get pictures. :)
