RE: Aquatic Plants Digest V5 #438


I need help.  I have a 39 gallon aquarium with about 20 small, quarter sized
angles and a handful of tetras.  It is a deep tank that has the footprint of
a 20 long. The bottom of the tank is heavily planted with Amazon swords,
Wenditii, and an anubias.  80 watts of tube light in a mixed spectrum, no
CO2.  I have a nitrogen problem.  The tank has two hang on the back filters
and a submersed powerhead with a sponge for biologic filtration, I did a 50
percent water change on Sunday.  Last night the nitrates were at 30 ppm.
This is a new issue, and the plants are suffering with Green Bush Algae.
The water is a bit hard and the ph is around 7.5-8, high for angles but
these guys are from a local breeder who has the same water type.  Because
the plants and filters are well established I would like to use them to
limit the algae, but I am open to other ideas.  I currently do not add any
other fertilizers, would K help the plants use the nitrates?  Does Ph have a
role in any of this?  Would CO2 help.  I'm about to give up on plants and
turn to African lake fish, it is frustrating....All help is appreciated
