I know you have funny hardness levels(low) in that tap water. Even so, the
crypts melting often seem to mean NO3/NH4 issues or lighting issues. I'll
rule out lighting. Bacterial and filter issues might cause some of this.
Crypts do seem to like hard waters in plant tanks.

Nothing like a good clean and big water change.

I'd do a narly cleaning, but I'd not start over and tear the entire tank
down. Check everything, CO2, NO3 and PO4. GH and KH? Try raising those up
some to 5 and 5. Don't move the plants around too much if you were before.
Prune the plants and toss out the bottoms saving only the tops for
replantings. Clean that filter, scrub those walls, scrub that wood. Net out
everything that you can that's floating. Do the water change. Repeat.

 I know you've heard this before but something's going on here and I think
something is being overlooked. You've had chronic issues and lots of algae.
Try bushy noses for the Green dust and try stopping the traces for a week
and watch. Up them later if this works(the plants will recover). Feed fish
You can use a UV and or a diatom every now and then but it's certainly not
needed as a regular component in a plant tank. A net, an algae pad, fingers
and vacuuming water changes can achieve a lot.
