Re-start - transfer plants or no?

[igirisujin]

Hello,

I currently have a Mini M set up with an ONF Nano light (9 hours between 50%-80% intensity), Eheim Ecco Pro filter and a FE CO2 kit at 1bps through an ADA music glass. I'm dosing 2ml TNC Complete per week, and changing 70%+ water per week. Water flow seems decent around tank.

I've had real issues with very heavy sediment buildup and very fast-growing BGA, and haven't been able to shift it. It's the first time I've had this problem in years of aquascaping. (BBA was my nemesis in Japan!)
I've varied my level of ferts (and periods of no N/P), tried weeks of lower lighting and removed plants that didn't survive (Staurogyne, Rotalas, H. pinnatifida). These are all plants I've had success with in the past.

I don't understand what's going wrong, and the only thing I haven't changed is the substrate. I've got to the point where I'm wondering if it's worth restarting, but I don't want to throw away the large amount of Bucephalandra that has grown, against the odds. It's not doing terribly, but quickly gets covered in BGA each week, before I siphon it off again. If I re-use these in the new setup, will I transfer anything unhelpful, or can I just give them a good rinse and put them in? Can I dip them in anything to kill off the algae before re-using them?

Thank you!

What sort of sediment?

I wouldn't mate. I made that mistake and introduced bba to my new aquarium

Brown mulm that builds up on the substrate and gets trapped between leaves.

That's what I didn't want to do, but wondered if it would disappear in better conditions.

Hi all,

I've had real issues with very heavy sediment buildup and very fast-growing BGA, and haven't been able to shift it.

I'd guess they are linked.

re-use these in the new setup, will I transfer anything unhelpful, or can I just give them a good rinse and put them in?

Personally I'd rinse and re-use them. Cyanobacteria are universal, so they will just return if conditions are still suitable.

An analogy would be every time your shoes get muddy you throw them away, while with a clean and a different route to work, (that doesn't include a muddy field), they are fine.

I suspect that's contributing to your issue.

Have you tried a complete blackout of your tank? I had a BGA infestation recently, was pretty bad until I did a complete blackout for a week. After that, I removed all the mulm and dead plants, reintroduced beneficial bacteria into the tank via used filter media and the BGA appears to be almost all gone now.
