Lost, need help

90G Tank is 7-8 month old.

What type/kind of Algae is this?

How do I stop it?

And how do I prevent if from coming back?

And sometimes I'm getting this greenish/brownish/hairish algae.

I also have this green algae on the glass, it makes the glass look like it has a green tint to it. I have been cleaning the glass everyday and it keeps coming back.







90G SW | 10G Bio-ball Sump | 125# LR | 2 T5 Fixtures | 1 Corallife Fixture | 4 T5 54w Actinic lights | 2 T5 54w Power Glow lgihts | 1 #4 Hydor Koralia| 3 #3 Hydor Koralias | 2 Peppermint Shrimp | 1 Yellow Tail Damsel | 2 Ocellaris Clownfish | 1 Frog spawn w/ about 10 heads | 1 Candy Cane w/ 2 heads | 33 or so Zoanthids on a frag disk | 1 Xenia w/ 3 families | 1 Hard coral ( don't remember the name right now) | 1 Cleaner pack

 

diatom, cyano, a good clean up crew with more flow should help. do you have a skimmer? whats your PO4? NO3,4? Si?

 

+1 Try something that sifts sand as well.. like a conch maybe. I don't like hermits Maybe you do.. they'd probably help a bit. Love your rockwork. Looks great.

 

More flow, are you sure I need more flow?

1 #4 Hydor Koralia, 3 #3 Hydor Koralias, plus the sump pump.

I didn't clean the tank yet today, gonna do it right now and do some testing.

Edit: Yes I have a skimmer, but it was bought when I bought my 29G. I do not remember what pump came with it or if it is even good enough for the 90g. Is there a way to find out?

 

more flow across the area

 

Nerite snails knocked mine out.

 

Reduced nutrients in your water!
Increased flow in the benthic(substrate) area of your tank! Light bulbs may need to be replaced as well!

 

All Bulbs are 4 months old if not newer.

 

This might be a dumb question, but have you cleaned your bio balls lately? If not this might be part of your problem.

 

My understanding is that you are not supposed to because then it will create another cycle.

Now, I have filled up the sump to where the bio balls are underwater before.
