melting plants

[benkho]

I just bought some Vallisneria americana (I have both the dwarf and tall)from altum_lover and planted them into my tank. However, they have been melting for the pass few days. I'm not sure as to what is the cause of this.

My tank conditions are:

55W PL light
CO2 at 3bps
in the right doses:
Fluorish excel, iron and trace elements.
Nutrafin NPK

Is there anything missing? Root fertilisers have been added to the areas that they grow in. My hygrophilla difformis and a crypt that I have are growing fine...so I'm at a lost... anybody got any suggestions?

What's your tank size?

Maybe can float some of the plants (so they are closer the light) and see if they grow new roots and leaves before planting. They may need to adjust to your tank condition which may explain the melting.

It's a 2ft tank...it already had roots when I got them...would I still have tfloat them then?

I haven't really experienced such a thing when planting new plants

Excel is known to cause melting in Vallisneria species.

They probably have not adjusted to your tank parameters yet if they are newly introduced. Once they do, growth is very fast. Just leave them alone for the moment and they should bounce back quickly.

I see, the melting started before I added the excel...I supposed I'll wait and see thanks!

That explains why my vallisneria was melting... i've since switched to co injection, hopefully the vallisneria revive. Should i snip off the half-yellowed leaves?

You need to snip the whole leaf off and not cut like grass.

hmmm.....for my case, almost all leaves on the ones that I've planted have become somewhat dark translucent green. Should I remove the whole plant then? Or wait for it to be revived?

You can leave them first and work on how to get them to grow well for you. What kind of filter are you using for your tank and how are you adding the CO2?

I'm using the eden 501 and the CO2 is just diffused into the water through the rain bar

I would suggest you change your fertilization regime.

Fertilization regime:
Seachem nitrogen (10ppm of NO3 per dose 2x a week)
KH2PO4 (get this....2ppm per dose 2x a week)
Seachem Flourish (5ml per dose 2x a week)
Seachem Equilibrium (1/4 tsp only after weekly water change)
CO2 30ppm via dropchecker method with 4 or 5dKH water method and make sure the CO2 rich water gets to the plants via enough water current consistently.
