Default ZEOVit New Tank Algae Problem

The tank was open in June by following the ZEO 14-days guideline, I waited for 2 more weeks before putting fishes in July, x2 clown fishes, x1 flame pygmy angel and x1 turning emperor angel from my old tank.

At the begging, I do see a few algae, since none of the fished eat algae, I didn’t pay attention. Then, fishes die one by one, the NO3/PO4 were very high.

In order to solve the high PO4 problem, I started to over dosing start3 (5ml every 3 days) and sponge power (20 drops every 5 days) for 2 weeks because I didn’t had any living creature inside the tank.

While the NO4, PO4 dropped to ZERO in 2 weeks, I converted start3 and sponger power to normal level. But I start seeing more algae.

Since last weeks, I put some SPS and x1 yellow tang tried to clean up algae. While, the SPS are maintaining ok, but yellow tang does not event bite any of these algae. The worst of it, I don’t see a trend of algae reduction in the past few weeks.

What should I do to get rid of these algae?

A little thought, if it is me

200L
Zeo Bac 2 drops, 2~3 times a week
Zeo Sponge Power 2 drops every other day
Zeo Start 0.2ml x2, daily, morning/night
Zeo CV 2 drops, 2~3 times a week
Zeo Food7, Zeo AA, can be temporarily suspended

Get the hourly output of the ZeoVit reactor,If coral health should maintain continuous flow, not the way of spacing

Try Zeo CoralSnow 4ml, every day, do 10 days
At the same time adjust Skimmer wet, change water 5~10% per week
Get some functional animals, such as: snails, sea urchins

Additional to Jackies advise removing the algae regular with some kind of a brush will speed up the process also. Once they are short animals should start to eat them, a sea urchin like:

https://www.meerwasser-lexikon.de/ti...s_gratilla.htm

might be a good addition also.

Thank you Alex and Jacky! I will try with the suggestions!
I currently have hermit crabs and yellow tang in my tank, they keep ignoring the algae.

Are these typical green algae? Because it is weird that yellow tang and hermit crabs don't eat it. In addition, the algae does not bleach as it suppose to do. Thank you both!

They are not like the green algae in my cognition. It is like a sign of excessive form. Maybe, I can't tell you anything. Get Zeo CoralSnow 4ml added every day, this should help with this problem and get some sea urchins. And the aid of artificial way toothbrush cleaning

Try #5's suggestion to see if things improve. If the coral is healthy, use a container to collect the reactor flow for 30 seconds, volume x120, for hourly output.

Pictures are not very clear but it looks like green hair algae. Animals do usually not eat them if they are longer so removing them manually additional is necessary.
