phosphate vs copepods/invertebrate

[xeanliao]

Due to lack of maintenance for long periods of time, the algae broke 2 months ago, that caused most of corals died ... (even my out-of-control purple mushroom died, too)

Most of my observation seem understandable, except I also found my dragonet is becoming very skinny, no pods to be found anymore. The most odds observation is those margrita snails refused to put their feet on those algae. They rather flip upside down without lands on those brown/green algae, I have three tangs they used to kiss the rock all day, but they don't touch those algae at all.

I would guess algae outbreak may benefits pods and snails? with Phosguard, the algae immediately under control, but my dragnet seems dying. Do you think there is something else going on?

my tank: 90g display, 20g sump, 4 clown fish, 1 yt, 1 bt, 1 tomini tang, 1 yellow clown goby, 1 randall goby.

How old is the tank? How big is the tank?Dragonetts can decimate a pod population in no time unless the tank is very well established..

it is about 5 years, 90g display with 20g sump.

Your post is a bit confusing.
Do you have algae now or not? If you have something that the snails and fish dont eat it could be cyano or other bacteria or toxic algae.
The dragonett is starving. If you dont see pods, you dont have them. You need to add pods and maybe a feeder that it can only enter to eat.

Yes, I still have some algae but they are diminishing and fully under control by phosguard and water changes. Per "...other bacteria or toxic algae..." what is toxic algae? I will take a picture when my tank light on. Is any general treatment other than gfo or Phosguard?

 

[xeanliao]

see pictures of the algae. Used to be 2-3 times more a week ago before I installed phosguard with media reactor.

Are they toxic algae?

I would keep on using phosguard since your algae is going away.
There is no way for me to know if it is toxic or just tastes bad to your tank inhabitants.
