[quote="JouteiMike"]Excellent points, Willow.
thank you.
the reason i wondered this was because i seem to remember
something about light,neutrients(sp),and algae.
they make a nice mix.
i wonder is the answer just a simple cut back of all
these things to make it better ?
and in what measure would be good ?

when you set up a new tank,hide an extra
sponge or two behind some decor,that way you have
something seeded for you next filter.

Yeah. The algae feeds off the excess nutrients and light. No matter what though, a healthy tank will always have some kind of algae growing. Like I said earlier, with proper maintenance and proper feedings and light cycles, you can control its growth.

CO2 would be the fastest fix I can think of, pressurized would be the best. The plants are using some nutrietns but not fast enough to out compete the algae for nutrients.

From my personal experience, I only encountered algae when I had a lack of something, never from excess. I actually dosed 30ppm of nitrates in my tanks a week along with 1ppm iron, .88ppm Phosphates, 50ppm potassium, 40ppm calcium and 4ppm magnesium. When I had Excel I had no algae problems although I did always have a small amount at any given time. Even though I do not haVe an Excel left right now I do not have very much algae growth and it only gets bad if I do not clean the walls of my tanks once a month or so.

I would suggest changing a little more water more often. 30-50% weekly will really help to get rid of the dissolved solids that build up over time. 20% weekly would be a good step.

Lighting amount is good but the duration is a little high. 10 hours is plenty and your plants will not suffer from it. As for the moon lights, I don't think they have much if any impact on algae or the plants, but they do look cool and are supposed to let the fish rest while still being able to see them at night.

Do you have idea what kind of algae you have? If you could describe it the best you can then we may be bale to identify a specific nutrient deficiency that could be causing it or another cause.

I have to say that my BN did awesomely for me and algea. I got a gold one, and he's lovely, very active and great at cleaning algea.

However, as others have said, you may be pushing it a little with stocking, and adding another fish is just treating the symptons not the cause...

But i do love a BN!

Here are a few pictures of the algae and my plants. I don't know what kind they are, so if anyone can tell by the pictures that would be great.

I just bought an inexpensive CO2 Biosystem from the lfs it's made by Red Sea. I'm also gonna start feeding for only 2 min twice a day and increase my water changes to weekly and switch the lighting to only 10 hours/day. Hopefully all this helps.

Should I continue using the Flourish Excel even though I got the CO2 system?

The plants look like they are not true aquatics.

The algae looks like diatoms which will go away when the tank or the ornaments become established in the tank. Usualy takes about 3 weeks for them to go away.

My Java Fern had a lot of algae that looked exactly like the one in those pics. My BN Plec ate it right up and the plant now looks cleaner than when I first got it.

I have a same problem on my 1 week old 29g. I know where my problem came from, maybe it is a same thing for you....

I put too many nutrients in it for my plants, and alge started to feed on them. cut down the level of nutrients you give your plants and get a pleco or couple of big snails not the pesky little ones.
