SOS Help! Plants are melting in their pots!

[Jaap]

Hello,

I bought some plants a few days ago and kept them in their pots in a tank for a few days until all my equipment arive to setup a new tank.

I dose CO2 with an atomiser and dose EI but the plants seem to melt.

Is it because they might have grown emrsed and now melt under water?

What should I do to keep them alive?






Thanks

Keep changing water...some plant don't like NH4

There are no plants that dislike NH4.

All commercial nitrogen fertilizers as well as Tobi's DIY fertilizer use some combination of Urea and NH4NO3. NH4 provides a much higher Nitrogen nutrition per unit weight than any other Nitrogen compound.

For the umpteenth time plants melt, because of poor CO2 uptake=> http://www.ukaps.org/forum/threads/what-causes-leaves-to-melt-and-what-to-do-now.20421/

The same would have happened if the plants were pulled out of their pots and inserted into the sediment. Pots have nothing to do with this situation.

The plants were most likely grown emmersed and so it would have been better to keep them out of he tank where they would have had better access to atmospheric CO2. It's very difficult for these plants to be dunked in water and to just carry on. They are drowning and they need more CO2. It would also have been better to just leave the lights OFF for a few days. This is the same issue over and over again people. When will we learn?

even for easy, low maintenance plants? Come on man I went for the easy plants for a reason 🙂

Now that you said that, the only plants doing good is the Valisneria probably because it was under water from the begining?

Clive is there any value in leaving them float for some time first, leaves being closer to the surface or even some out of the water. That is to change into submerged form easier?

Ok so that it will make more sense to me....these plants were grown emersed and now they are drowning EVEN THOUGH I am adding CO2.....at some point new leaves will grow?

I mean I had dwarf sagittaria in tanks with no CO2 and now that I placed them in a co2 enriched tank they melt?

Is there a difference in the time for the plants to recover between plants that need alot of co2 and plants that need less?

Well again, do not compare CO2 tanks with non-Co2 tanks because the adaptations and conditions such as light and so forth differ. Plenty of plants melt in non-Co2 tanks as well, so it's a very broad brush to paint with. Did the plants in the non-CO2 tanks transition easily without melt or without other issues? If so is it always the case? Probably not.

Just because you are adding CO2 it doesn't automatically mean that you are adding enough CO2 for these plants under these conditions. Pummelling plants with light just after flooding is not really the best way to go. The transition is difficult for them and adding light stresses them because it drives the CO2 uptake demand unnecessarily high.

There is always a difference in adaptation because conditions are always slightly different, species are always different and even individual specimens are always different as well.

according to Tom Barr there are plants that don't like to much NH4 which is leaches in to the water with new substrate at the beginning..
But CO2 will also be a big (probably the biggest) problem here
