Ok... Lets not be too harsh on a newbie, we are all here to learn... Yes, tangs will not solve ur hair algae issues... Try getting a good cleanup crews instead... Seahare( but they can grow quite big), Turbo snails, blue legged hermits and red legged hermits are known to help control hair algae... And i say "help"... Cos these are only temporary solutions to ur hair algae problem... Try to find the root problem on why theres a hair algae issue in your tank. I believe u have a fairly new tank and its probly still cycling or just finished cycling, which is quite common to have algae issue during this stage.... Control your nutrients level and check on your water parameters, frequent water might be all it takes to solve ur problem... Good luck
