Hi. I've started a new tank using dry start method and would like to ask for some advice.

As a substrate I've used planting soil (natural, no fertilizers) capped with 2-3mm gravel.

Plants: elocharis mini, reineckii nana and hemianthus cuba.
The tank is 11 days old.

So, some parts of hemiamthus started to get dark green after around 7 days and became "slimy". After around 12 h they got covered by a web-like substance (not classic "fluffy" mold). Rest of the plants are healthy and grow nicely. Also the problem seems to occure only on some HC, not the whole carpet.

Temperature is around 22.9 C - 23.5 C and the humidity is 90%+, I spray the plants with water every day and ventilate for fresh air

I would be greatfull for some advice.

Hi all,
tarted to get dark green after around 7 days and became "slimy". After around 12 h they got covered by a web-like substance (not classic "fluffy" mold).
It sounds like it is a "fungal" disease caused by Pythium etc.

The English name <"damping off">.

cheers Darrel

Thanks for the reply. I read the information you've provided and since there is no apparent tested solution of the problem I will probably flood the tank earlier.
The infection is spreading so I don't have much choice.

Your substrate looks very wet, so that may have some effect

I’d trim/remove as much of the degraded HC as possible before flooding, anything advanced is just going to continue melting once flooded ... are you able to add shrimp or snails soon?
(they are usually more efficient at removing individual damaged leafs)
