Ive been considering Ulva algae. It would be in my sump that Im slowly converting/retrofitting with a refugium. Just removed the bioballs… The Ulva was looking good for a few reasons:
1. Low chance of it spreading to the main tank and becoming a nuisance.
2. Removes phosphate and nitrate.
3. Doesn’t absorb calcium like Halimeda.
4. I can collect it from the local beach (along with other algaes)
5. Supplemental food source for my snails that have done an overzealous job of removing diatoms and have since moved on to my newly acquired live rock and have just about mowed their way through that
6. Nutritious for us humans
Any experiences with Ulva?
* question in regards to # 4: Would a simple rinse with salt water before adding Ulva harvested from a local beach suffice or should it be quarantined?
