This removes the most bad stuff possible. The additional new water helps the cause too.
3. Vodka and/or vinegar... it will work
4. Elbow grease... where possible remove the HA. You could remove any rocks that are possible to remove and scrub them with H2O2 also.
5. Run GFO & pay attention to when it is depleted

If you have HA, you have available nitrogen and phosphate regardless of whet your tests say. Don't add more. Quit adding stuff to "kill" the algae. Be patient.
Yeah... .ive done all that. I personally think my rock is the problem. Dry Marco rocks make up most of my rock. I suspect they are leaching a ton of po4, and the HA/RS out competes everything else.
