There is no guarantee that shrimp, snails, or fish will eat your algae.

You need to find the right balance of light, CO2, and ferts for your tank.

Are you using pressurized CO2 or DIY? DIY CO2 is not very stable. Fluctuating CO2 levels can lead to algae.

He's right. Hair algae is also a big indicator of too much light. I'd cut back your photoperiod even more to see if helps. Spot treat the existing stuff with excel or h202. How long are the lights on and what kind are they?

A picture of the tank would help, but you need to state exactly what the light is.

As they said, cut your photoperiod.

Also try adding a bunch of floating plants as shade, and to compete will algea.

You may want to dump a bunch of hornwort/elodea in there too.... you can just float it.

Plants release chemicals that fight algae, the more plants the less likely you are to have algae problems.

I have very minimal experience with hair algae but I'll add in my $.02. I have a low light tank with low light plants. So not much need for ferts. Well I tried adding in some trace ferts and regardless of the quantity I add the next day there are a few wisps of hair algae blowing in the current. About a day later it clears up. So my anecdotal advice is reduce ferts if you are using them.

I use flourish excel each day and that iron doesn't seem to have any affect either which way.
