Slightly Brown Water?

I noticed the water in my new 5 gallon tank is crystal clear, while the water in my 1.5 year old 29 gallon is tainted brownish. It isn't visibly brown, but when I do a water change using a white bucket, it is slightly tinted.

I'm wondering if there is a cause for this and how I can work on fixing it. Is this an indicator of something specific being wrong?

In the tank I have...

2 female endler-guppies
3 male endler-guppies
2 dwarf puffers
9 neon tetras

I feed once every other day and I do water changes (20%, but this is only recently to keep ammonia down since I've added a lot of fish) a few hours after I feed. I usually vacuum the substrate from a distance to pull off and detritus that has built up. I have lots of plants in the tank.

What should I do about this issue?

If its not tannins from some kind of wood then I would think it is caused from decaying organic material in the water. Plants, food, waste, etc. My tank is like that all the time, but I always have lots of wood in there.

What's your substrate?

Water tests?

Do some water changes. Any driftwood or IALs? Any tannins in the that might be affecting it? I'd say just do a substrate deep clean if you can, just to make sure there's nothin in there screwing with the water color.

No matter how hard you try, you cannot escape this hobby. You have been warned.

Yeah, I do water changes at stated in the main post...

I do have driftwood but it has been boiled before. It's been in THIS tank for 1.5 years, but I've had the two pieces for many, many, many years.

The sand isn't deep, there's nothing in there. I often vacuum it.

Try running purigen. I heard it removes tannins.

It doesn't really sound like there's anything wrong with your tank. However, if you want to get back to crystal clear water, purigen does a great job.
