Thanks Devin. But I need to correct that last post. It was not 0.7ppm ammonia, it was 0.07! Sorry. That was an important decimal!

So, with that in perspective, you can see that I don't have a BAD problem. It's just that I do have some measurable ammonia. Not much, but it's there.

With an established tank, an Eheim Pro II and an Aquaclear filter, I should have an abundance of biological filtration. I think it's just a matter of fish load vs. plant load, with water changes that could be more frequent. Currently I'm an an equivalent of 50% every three days. Yes, many planted discus keepers do more lie 50% every week, but I'm not heavily planted, and I've got 8 adult discus.


As for the annubias, I just cleaned the tank and found more. Almost every one was a newer leaf, with not much GSA (an indicator of good growth rate), no yellowing or distortion, pin holes,... what ever. Healthy leaves, with firm stems EXCEPT for the fact that the base of the stem was soft where it had been connected to the rhizome. And the one exception was a mature leaf that was dark green, and it had separated from the stem.

It's curious.
