Algea identification assistance

[fishnoob~noclue]

Hello people,

I've had a bit of what I thought was bryopsis issue before adding a small does of reflux for a quick and easy solution to an ugly feature in the tank.

Been about a just shy of two weeks since the dose and this new bright green has appeared to take over. Can anyone provide any assistance on what this is and how I get rid of it, if you can it would be appreciated.

My readings are :

7.8dkh
Phos 0.1ppm (I know it's high, I think my phosphate reactor is broke, but was turned off when treated anyhow)
Salinity 1.255sg
Nitrate 15ppm


Thanks

Looks like either GHA or a turf algae. Bad thing about chemicals is something else will pop up and create a new problem. Number don’t look crazy heck my PO4 is at .2 and NO3 25. What clean up crew do you have and how bigs the tank?

Sweet thanks man, do you reckon if I lower phosphate levels that'll be the end of this new turf algea? How do you run a algealess tank with higher levels I've got sunlight on it most of the day which doesn't help.

I've got a red sea 250l with a ever disappearing clean up crew which consists of:
The clean up crew Emerald crab x2
Small Halloween hermits x3
Blood fire Shrimp
Cleaner Shrimp
Uncertain on the amount of snails approx 10 still about

I have a mix of snails. Probably 20 or so dwarf cerith, 10 Florida cerith, and 8 or so astrea snails. All in a 25g tank to keep algae at bay. I also refer back to the reef cleaners algae guide a lot to see what eats what.

Maybe I need to bulk up my clean up crew, think my emerald crabs might eat the algea but I may be expecting them to eat a bit too much, I have a lawnmower blenny but not sure if he's eating it.

An urchin or two might help as well just make sure any frags or coral are glued down as they will bulldoze everything.

Get your hands wet daily. Harsh chemicals ruin your biome.

Are you running a protein skimmer? Have you considered carbon dosing?

I would recommend trying to manually remove as much as the algae as possible, followed by large(ish) water changes. Your true number of P04 in your system is probably even higher than that right now, because they get leeched into the sand and rockwork and consumed by the algae that you currently have. So, my advice would be to manually remove as much as possible, always followed by a water change to solve your current nutrient/algae issue, and consider carbon dosing in the future, more as a preventative measure. But only if you have a protein skimmer!
