Unhappy Endless yellow water situation

Hi folk, my fish tank was in a yellow water status since last month, I dosed seachem flourish excel into the fish tank for micro_nutri.

I tried
1. regularly water every day for 1 week;
2. drain the whole tank and refill fresh water;
3. increase my filter power, decrease light;

None of those worked, the water just turned more yellow every day, and my bottom plants begin to show me the signs of melting.

Here some necessary information:
1. I haven't tested my water parameter yet.(will do this weekend).
2. The water smelt like sulfur.
3. There are some melting plants in my tank.
4. None of the living fish and shrimp died during the yellow water condition.
5. I dose CO2 booster every day.

And I will attach a photo of my tank.


And a photo of it 1 week ago, after I changed the overall water.

You say you're dosing with Seachem Excel (which is NOT a micro, but a pseudo liquid carbon!) AND You mention dosing (and I see) API CO2 Booster!!!!! You appear to be double dosing a strong chemical.
STOP using these for now and do a couple of water changes.
You do not need Excel or CO2 Booster unless you have high light and are dosing high ferts (macro and micro).
Instead I feel you would be better served using modest amounts of Flourish Comprehensive (macro) and Flourish Trace (micro) again in very modest amounts.

What @AbbeysDad said.That looks like a piece of driftwood and if it is it is probably releasing tannins into the water for that I would also suggest you try purigen.

I'm sorry, I'm using Seachem Comprehensive with CO2 booster, it's a "mis-copy-paste". But I will stop using them. Such a shame I spent much money on buying Co2 booster every month lol. (what's the average money cost to setup a 20 gallon tank, low tech? )

I dropped Flourish Comprehensive 1 ml one month ago and it began to yellow my water.

So here is my plan: I will stop dosing anything into the water and begin to do a 10% water change every day.

The wood was from local Petco store. The tank in Petco(which have 10+ piece of wood in the tank) is crystal clear, so I didn't take any further action after I purchased them from the store. Maybe it will be a cause.

Thats because they most likely are using carbon to remove the tannins.

Purigen will take care of it quickly.

Activated carbon in the filter will take care of it over a longer period of time.

That piece of driftwood looks small enough to take it out of the tank and place into a bucket of hot water. Soak it for a while so most of the tannin leech out of it. Otherwise you'll have to just wait it out, and it can take months of it to stop leeching tannins into your tank. On the upside the yellow color is not harmful.

You can solve it easily with active carbon filter. In my experence, there is a possible that it is algae bloom. In this case, active carbon filter is useful.
