Water change will always help. It is not a good idea to cut CO2. CO2 is carbon and is very important for plant growth.
Hi all,
Recently after coming back from holiday my tank was overgrown with algae. So as a standard procedure I cut co2. However the plants are now facing a massive die out, especially the long leaf ones (see in picture). Is this normal for plants to be so dependent on Co2? Currently I am dosing Excel to kind of supplement the plant growth but is there anything else I should do? Thanks!
Tanks spec
20l with 2 HOB
Lighting 2 LED brand idk
Co2 1bps
ADA Amazonian
Cheers,
Happydanio

What did you stopped adding to the tank during your holiday? Lighting and co2 were on the timer when you were away?

my guess is the absence of CO2... when my CO2 run out , I'll experience yellowing in my gujing when CO2 is up again it grows nicely again..
Yeah, your plants were just adapted to grow with Co2 injection... when you cut it suddenly, they go through a transition to non-Co2 injected environment, so the old leaves start to deteriorate.
Usually in such cases, the new leaves that grow out in the non-Co2 environment will be healthy as they have adapted to it.
Ideally its best to maintain stable Co2 injected conditions for your plants if they have been growing well in it. If you want to stop Co2 injection, it should best be done gradually (along with the corresponding reduction in light and nutrients too, since their take up rate will also be reduced), so that the plants can transition more easily.
Btw, those background plants look like vallisneria? Those types of plants tend to be quite sensitive to Excel, resulting in melting. Could be a possibility the chemicals might be contributing to their worsening condition too.
Stable CO2 supply is especially important.

Strange... But the front plant refer to the picture is in full bloom though.... Was it affected by Co2?

I'm using a GEX HOB in my 20L and the flow is terrible. perhaps consider a better external filter or powerhead to improve flow?
Thanks everyone for your constructive feedback! Planted back and everything goes back to normal. Guess it was the co2
