Re: Plants for Goldfish/Blue-Green Woes
Jefferson Ong asked about plants for a goldfish tank which would
survive hard water and 1 tsp./gallon salt as well as provide a
salad for the tank's occupants.
Hornwort, Ceratophyllum demersum, fits the bill, but may not
grow quickly enough in the salted water. Although I've not
kept goldfish, I doubt that the salt is useful. It is most
likely detrimental to their health.
Jonathan Kalmes has a problem with cyanobacteria in a 75 gallon
tank lit with two fluorescent lamps.

Something's wrong with this picture. Are the plants producing oxygen
bubbles? It may seem a littoral jungle going nuts, but my guess would
be that you could do with more growth pumping more oxygen into the
water column. With lighting at one watt per gallon what types of plants
do you have? Are they submersed or floating? Try a circulation pump.
