Help my Frogspawn

I appreciate all of your responses.

Since moving it higher onto my hellish rocks, it has really taken off, and some branching is now apparent. Maybe one-in-ten tentacles is growing a branch. It looks almost exactly like the first FS picture that amcarrig posted, but I agree, it is a tough call. I moved it to a more open area so it can expand.

As I said, Nitrates are undetectable. I've used only RO water, but I'll be testing for Phosphates later today, because I'm curious too.

This is a new tank, only a couple months old, put together with parts of my old freshwater setup. I don't have a protein skimmer yet, it's just circulation and live rock. I used someone else's old sandbed (kept wet, but in buckets for several hours), and cycled with uncured nasty live rock. I'm not surprised if it is a nutrient-rich environment for algae. I'll be getting a skimmer soon, but the fish are healthy, the snails and hermits are loving it, and I can live with it for the time being.

 

I agree with torch as well

 

Phosphates at zero in my tank and my RO water.

 

good news Spork - location definitely a big factor, keep it clear of the rock work and it will expand better
get another picture up as the ID aspect of this is interesting
