moss ball nutrient use
 
i need more plants for my tank, the lfs's in the area have very limited supplies, but they do tend to have moss balls (don't remember the other name for them). i have rather high nitrates and am looking for something to help keep them down. how much good would a moss ball or two do?

This is advice i have got from someone on here with more experience than me, moss balls are very slow growing, meaning they won't absorb nitrates, you need fast growing plants to remove nitrates, the best are floating plants they grow very fast, look very nice, are easy to obtain online or from eBay which is where i got mine from. They grow so fast that you can scoop some out and sell it :)

floating plants are what i have. i want some val or swords, but am having trouble finding them and would rather not have to ship them just now (too great a risk of frost these days).

Someone can correct be if I am wrong, but I do not believe there are a lot plants that efficiently use Nitrate. Plants keep down Nitrate by using Ammonia before it is converted to Nitrite and then Nitrate. So basically no plan will solve you high nitrate problem, but if you add plants and then do some water changes the Nitrates should not go back up again.

that is true, perhaps i should have said "prevent nitrates" rather than "lower" them. but the end results is the same: more plants=lower nitrates.

I'm not sure then haha :) *waits for more advice* I have about 4 different kinds of floaters, they look messy right now but would be better when they have grown in.

I forgot to add that I have had a Moss ball for 6+ mo and have have only noticed a negligible amount of growth. If I were trying to lower Nitrate in my tank I would use a fast growing floating plant like hornwort or riccia.

Moss balls are quite pritty though, but because you have a common pleco i wouldn't recommend if you want them to stay in one place. I have a common pleco and when he's on a rampage my 3 moss balls get thrown around the tank like balloons, they are forever in different positions in the tank!

I think there might have been another thread about the nitrates...? This subject comes up often, I can't remember precisely.:-)

Anyway, floating plants are one of the best utilizers of nitrogen (ammonium, preventing nitrate as you correctly stated) so the better approach might be to find the source and deal (if possible) with that. What is the nitrate reading in the tank, and has the source water (tap) been tested?

While its true plants consume ammonia first and nitrate second, it doesn't mean they don't have an impact on nitrate. My old tap water use to be high in nitrates (20ppm) and some of my tanks could take them down close to zero after a week. You need a lot of growth though, then the weekly trimming..... Also remember EI or dry fertilizing uses nitrates. My new tap water has zero nitrates so I added them now. Plants can definitely consume nitrates, its just the more stable nitrate molecule requires more energy to utilize then ammonia does.
