I think lines got cross a little. I DON'T have algae with the live plants,
I have zero algae in my tank, no need for plecos and algae eaters. It's
just that after 2-3 months and the plants get real sparse and shabby
looking. I don't do the CO2 thing (not even sure what that is and if I want
to get into it) but I have very good filtration, water flow, and my
parameters are perfect. I also do have Flourish nutrient in the water I top
the tank off with.

I like Cabomba, they keep growing for me, but I wish they would keep looking
nice like when I first get them. I just wondered if this was typical of
Cabomba.

Also, my three tanks are only 10 gallons each and the lighting, well don't
laugh... the lighting I have is only incandelescent and I can't change that
unless I get all new tanks. The tanks were the Eclipse style with the hood
and tank combo (but not Eclispse, some off brand of a similar style). So,
do you think the incandelescent lighting is why the plants don't do as well,
or is that not an issue?

My other question was if it was possible to maintain a tank with zero algae
with fake plants or decorations too, and how one could manage that. With
artificial things I always have an algae farm. In one of my smaller tanks I
would just like to have some rock, driftwood and coral pieces, but algae
forms on this stuff and looks aweful.
