Hi,
I'm new to this forum and I like what I see in the posts.
Perhaps someone can help me with a question:
Aquarium Information:
Tank 48x12x24, 90 Gallons
Light: 4x54W T05 Powerchrome midday ~6000 Kelvin
Substrate: Sachem Flourite 15lb
Heating: 200W & Root Therm 400 85F
Water: GH: 5.0 (85ppm), KH:3.0, (51ppm) NH4 =0, NO2=0, NO3 =0 , according Test kit, ph 6.6-6.8
KH and GH values are in german hardness, the water is pretty soft
Filter: Wet Filtration system with EHEIM sump pump, Bioballs etc.
CO2: Yes
Water change: weekly, about 30%
History: The tank was started around Thanksgiving 2007. I ran it for about 3 weeks without any fish, then added 4 Plecos, a week later 13 Harelquin's and another week later 5 Rainbow, 2 Pearl Gurami's, 7 Chinese Algae eater and 3 Bamboo shrimps.
At the beginning the color of the tank went greenish, so I thought the nutrients especially with the fluorite was causing a algae bloom. So I added a carbon filter without any success. Then I switched to a diatom and the water became pretty clear. However green algae and hair algae started to develop.
The Tiger Lotus exploded and showed a wonderful red color. The rotala's, myrophillum, cabomba and Ludwiga's grew well too, The echinodorus bleheri and the vallisneria didn't want to grow at all.
Now the vallisneria take off but the Tiger Lotus, the cabomba and the Myrophillum came to a halt.
Since about a week I noticed that blue-green cyanobacteria are starting to develop.
So I was wondering if my phosphate levels are too high.
Does anyone have a recommendation of a good PO4 test and what levels should not be exceeded.
I already checked the city water report but there is no indication.
Any help or advics is highly appreciated.
Thx
Wolfgang
