There’s not one single bandaid that will fix gha. I’ve found it to be a combination of things. You may have your lights on for 12 hours. Cut it back to 8. Your tank may be receiving 4 hours of morning sunlight each day, not good fix it. Your test kit determining that you have 0 phosphates may be significantly off. TDS in your water source. Hopefully water is not from lfs. Water quality in is an important factor. CUC, like purchasing 30 turbo snails, or 50, way more than you’d normally need. Pick it off of rocks often. It’s a living thing. It won’t like or appreciate that. Annoy it to death, constantly! Blow off rocks, vacuum your sandbed at least monthly. Keep things pristine. GFO or Phosphate Rx would have made the list but you’re saying your phosphates are zero. Consider your feeding habits. Cut back if you need to. Cheato is a good thing but by itself won’t cut it. If you can do all of the above, you can see results in 4-6-8 weeks. Good luck. Proclaim allout WAR!!!
