Hi,
Sounds like you have some slime algae. Skimmer can help, might try some high grade carbon too, or purigen. There are some chemicals that can help, but only as a last resort. I've used them before without any problems, but better to not use a chemical if possible.
Aquac send us a message back and said they are making that item, but no ETA because of there current overload on supply/demand now. So I wouldn't count on it anytime soon.
thanks
