Green Filter Squeezings

If you had a good seeding of bacteria, you should have seen an immediate decrease in ammonia. Sounds like the bacteria were never there or didn't survive. Your tank will cycle fishlessly with or without a seeding, but (as you're seeing) unseeded tanks take a while to cycle.

Hang in there.

And it was from Freshwater tanks, right?
