A feller from New Zealand gave this suggestion you might consider:

You cam try getting some soupy wet soil and putting it in ice cube trays and
freezing it. Then take these soil cubes and push them beneath plants etc to
recharge things.

Soil tanks will wear out if productive over time. If you have high enough
fish load, their waste will extend the life of the substrate some.
I use flourite just like folks use soil and the results were great actually.
I did add more peat than I would for a CO2 tank and a good bit of mulm from
another tank. But I've never had an issues except great looking tank using
it and no soil mess.

It's hard to know when etc things are not doing well what is happening but
nutrient(s) being removed too fast and getting the tank out of balance is
always the cause. NO3, PO4, K or traces etc Non CO2 tanks are more subtle
