cant control nitrates while removing HA

[BlueAbyss]

Sounds like your 'fuge (and scrubber) aren't keeping up with the nutrient input. There are a few things you can do...

1. Cut back on feeding. If you feed pellets or flake, stop and switch to drained frozen (mysis works well).

2. Get a skimmer, if you don't already have one.

3. Chemipure Elite works well if you have a small tank, it gets expensive if you tank is larger.

4. Change your 'fuge so it's focus is nutrient export.
