Hi,

Is your no2 really 2ppm after 4 months?!
If so something is wrong there. It should surely be 0 by now.

Also your level of phosphate should be higher. Which is likely your problem with the sword.

Also just noticed you have t8 lighting, how many tubes?

Are you dosing any other micro ferts? Because if not your missing a few!

Well your nitrates are bottoming out (so you need to add more - If your sure the test is accurate)

I think you also need to increase your phosphate levels.

Also your missing alot of trace ferts.
You need to order some!

You haven't got all the lighting in the world so demand will be less but they still need them.

Concentrate on your dosing regime and investigate why your tank hasn't cycled.
I hope you haven't got any fish in there!

What test kit are you using for nitrate? I know many people get low nitrate readings when using a liquid bottle containing cadmium because they don't shake it enough to dissolve the crystals forming in the bottle.

That's fine

But concentrate on the rest of the ferts.

Plants need all these ferts to grow well.

If any is missing then others don't get used/utilised.
