Foliage not doing so well...

I have an Amazon Sword and a Hygrophila They both looked pretty good for a while. They all have really good root systems still. But the foliage is going down hill.

The Amazon Sword leaves are getting holes in them, you can see through them, and the tips of the leaves are turning yellow.

The Hygrophilia is getting new growth at the top but the lower leaves are turning black around the edges and kind of curling up.

Thanks in advance!


PH 7.0
Nitrates 40
Nitrites NA
KH 4
Amonia 0

What lighting and fertilisation do you provide in the tank?

I have 1 40 watt Power-Glo 18,000K light. I haven't added any fertilizer yet. I don't know the first thing about that and I don't want to hurt the fish. I have:

1 Red Tail Shark
1 Rainbow Shark
2 Clown Loaches
3 Spotted Corydoras
1 Zebra Bottia
2 Golden Rams
2 Black Iridescent Swordtails
2 common plecs

you could always get some root tabs,i have used them and
got on well with them,saved me measuring out quanity.

lighting should be 6500-6700k, that 18,000k is more a saltwater light spectrum,really nothing in it "useful" for plants

what size tank ??

I should have asked the size of tank from the start as well, as the colour of the leaves indicates either a lighting or a fert (or possibly both) deficiency. Root tabs are a good idea imo, since both of those plants are heavy root feeders and will appreciate some fertilisation near their roots. I like JBL the 7 Balls, as they last an awful long time (if left undisturbed) and are fairly inexpensive.

40ppm nitrates is highest it should be. Anyhting over can be harmful to the fish unless you add salt regularly and then you won;t have happy plants.

Nitrites:phosphates 10:1

The plants look like they are suffering from a lack of everything. Mostly light and Iron but nitrates and phosphates for sure and especially potassium. Looks like you have fast growth and the lack of nutrients is leading to the plant focusing on new growth and neglecting older growth.

Thank you all!!!

I would love to lower my nitrates. They are 0 out of the tap. But I have done water change after water change. And they just don't get any lower than 40.

Any more ideas on lowering them? Or why they aren't going down with the WC's?
