Anubias: What am I doing wrong?

[Cypherman]

The oscar is too small to dig up anything (I use a very large river pebble gravel; 1/4-1/2 inch in length), plus I planted most of my crypts in between large boulders so they wont be able to remove them very easily.

Thanks again for all of your wise advice, I will look into KCL supplementing. Yea I do run AC on both filters, although it isnt changed too often. I will remove them. Should I also ditch the ammonia removing resin and stick to biofiltration?

My apology.....I don't know what I'd do without Starry....she caught my bad. I did mean Potassium Chloride(KCl). Sorry about the mistake.
Just my opinion.......rooted plants will do much better with a smaller diameter substrate.
Fish create ammonia. The amount of plants should be in proportion to the amount of fish to be able to use the ammonia and other toxins that they will produce.
Your fish will eventually become large, especially the Oscar. Unless you have enough plants in the tank to balance the waste they create, you are going to need something in the tank to absorb it.
Planted tanks that are in balance with the fish load shouldn't need activated charcoal or ammonia absorbers. Whether your plant load can handle your fish load is a question you have to determine.

However, I think anubias likes large substrate. Mine loves the big gravel I have, and so do my crypts. Not all plants do, though.
My kribensis just spawned in my anubias, ignoring the caves I have for them. Strange!
