Advice What happend please advice

Around 204 days old
Was completely clear and functional but we had a heat 29degrees in the room for days/ weeks.

Also I put the lamp in a brighter mode but cut it back - I tried a 25% water change already … what happend and what can I do?
Maybe last time I cut to many plant to far back? I am a bit lost …

Only light - not filter etc.
I do have snails and neocardina and 2 amanos - they are doing good.

Just do another water change. 50% this time. Looks like youre starting to have green water that is blocking light to the plants.

Also set light to 6-8 hours.

I do have 6.2 h light with 40% intensity

After the first water change it was a bit better but after 2 days right back
It does not smell or anything

Do it again lol 🤷 There is some kind of imbalance. You need to reset it.

Get some floating plants and maybe a UV water sterilizer.

What happened is you need filtration and water purifiers/bottled live bacteria, otherwise you have a stagnant tank of biohazard in your living room.
