Bubble algae issue is getting way out of hand, I’ve got 6 emerald crabs in a 50 g display (90g system) and they haven’t made a dent. Manual removal isn’t really an option most of the rock work is covered in coral or fused together with putty making it way too large to pull out. I try to scrape some off between water changes but as you can see kind of pointless. Attached parameters below as well as photos of some dense areas. Photos were taken during a water change, don’t have many fish atm which could be the cause of low phos. Any advice to eradicate or just stop the rapid growth of this BA would be great!
