Thanks, that's good info! It's hard to search for this kinda stuff.Some aquariums have had success using various chemicals to treat eggs to prevent bacterial growth and manage amphipod/copepod abundance in squid eggs. Check out page 4 of this issue of Drum and Croaker: http://drumandcroaker.org/pdf/2020Issue.pdf
You may fund success repeating these treatments in your eggs. I would also suggest making a basket for the eggs to get them off the substrate, that may help reduce amphipod/copepod abundance in the eggs as well. Again see page 4 for suggestions from Monterey Bay Aquarium.
I have done Betadine dips on bandensis eggs before and it works well. I have never used Revive coral cleaner on eggs so I cannot speak to the efficacy of the treatment personally, but I trust the people at MBA.
Yes I took the substrate out and kept it in the breeding box in hopes of catching that amphipod.
Question: When you say Betadine do you mean the gargle/mouthwash or their antiseptic solution? And do you dip it in RODI water, or tank water?
