First one looks like Ludwigia Repens (primrose), second one looks like a hygro but not sure what species, the third looks like a fern. As for helping your nitrates, they should. I have primrose in one of my tanks and it takes out a lof of NO3 and PO4 so you may need to dose both eventually. If you start getting green spot algae, dose PO4, if you start to see a drop in growth then dose NO3.

No problem. NO3 is nitrates, PO4 is phosphates. Green spot algae is the stuff you get in the glass is really hard to remove. Low phosphates triggers this every time in my tanks. You will notice a very definate drop in plant growth if you are short on nitrates. The plants will simply not grow and you will not see new growth for many days compared to the rates you should have from Primrose if the levels are high enough. You may also see black spots on the edges of all the plants and the leaves of the hygro will fall off in low nitrate levels. Make sure to keep the hygro cut low so that the lower leaves get plenty of light, if it is hygrophila, otherwise they will fall off and make a mess not to mention look bad. I kept mine at about 4 inches and it grew into a thick lush forest in a short time.

And don't ever be afraid to ask more questions. I asked hundreds of them before I got a total grasp on it and I am sure I have more to learn.

50! OUCH! I don't think I would even drink the water. You won't have to add them, ever, not unless you add a ton more plants and even then I doubt it. If your plants use 4ppm a day then you could still have levels above 75ppm in your tank at any given time.

I know you have tested them but I would be testing them again and make sure to shake that bottle really good! I would also get them tested by the LFS, the water department and whoever will do it for free. That does not sound right and I don't think it is healthy for you to drink. Test kits can be faulty brand new and nitrates are a pain at times to measure anyway. Get it tested by others and if it is that high I would contact the city to findout why.

If the results are true, I would at least switch to 50:50 tap water and bottled water to keep them down where they need to be. I will try to find some Wisteria for you somewhere. I have some but very little but if I get it to grow faster I will send you some as soon as I can.

thats soo nice of u fish for all!! well i only have the test strips, in the tank the nitrates never go higher than 50 so perhaps its less from the tap, maybe 20 or something. ive had most of my fish for 5-6 months now and they r healthy.

I know it is an added expense but you need to get rid of the test strips and try to get a liquid regeant test kit. They are terribly inaccurate. I started with them also. When I got my liquid kit, I tested them side by side and the liquid kit showed 40+ppm Nitrates and the liquid kit showed less than 20.

My Wisteria is growing ok for now, I hope to have enough in about a month or so.
