Hi everyone. I'm fairly new to fishkeeping. It started with a "donated" 55 gallon tank. That tank is doing wonderful in the living room with plants growing beautifully and happy fish.
Now my problem is with my new 39 gallon tank that I try to get ready for some discus fish. My water parameters are: temperature 84 degrees Fahrenheid, PH 6.8, GH 100-150 ppm. Nitrate and ammonia levels are zero. I do not earate, it is an eclipse 3 tank with the mechanical, carbon and biowheel filter system. Lighting (probably not enough) 40Watts (2x 20 Watts bulbs) x 9 hours. My amazon swords do seem to grow a little, my Java fern doesn't grow at all. Green and bronze wentii (cryptocoryne) grow great as does pennyworth, but the water sprite does seem to die. I do have a little duckweed that seems to do well. 6 ottocynclus algea eaters are alive and kicking. Now this system has been cycling for about two and a half months and since the last two weeks I see black brush algea(BBA) developing on some leaves and on some of the substrate. A rosy barb that I put in there for a week, did not seem to do a lot, and the little ottocinclus neither. I can remove some by hand and it looks better, but is there anything else I can do? Would better lighting (say2x 40 watts bulbs make the plants grow better...but won't the algea grow more with more light as well?? What about a CO2 injection system?? or ferilizer (althuogh phosphates will make algeas grow...I thought).
All suggestions are welcome.
A "donated" 55 gallon tank rejuvenated my interests in keeping fish again in January 2003. I now have three tanks (55 gallon, 37 gallon and 29 gallon) at home and one at the office. I'm getting ready to dedicate one of them to discus fish. I'm very excited. I grew up in The Netherlands where my father and grandfather had wonderful planted tanks and I cannot imagine having a tank without plants, or even worse, with plastic plants.
