Hello Janice.

Your PH seems way off for Amazonia as a substrate (it should be more around 6).

I would use a small fine net and scoop the floating debris out of the tank or siphon it off during water changes.

Try to use a small plate or container when refilling the tank to divert the water laterally across the substrate. This will help to keep the Amazonia from moving about and creating more surface scum/debris.

I would also ensure that your water level is also high when using the Aquaclear HOB. This will allow for a more laminar surface flow and minimize a cascade effect that may disrupt your substrate.

JMHO.

What brand are your test kits? Some test kits are better and more accurate than others. Give the reagents a good mixing before testing and see if you have the same results. Your Ammonia should also be around 6-8 PPM.

I'm not familiar with the Nutrafin kits, but they could just be old. The API Ammonia test kit measures total ammonia and not free ammonia. Your PH cannot be that high with a GH and KH that low.
