Green hair algae

I have been fighting a battle for over 4 months now, and am starting to lose interest in the whole hobby because my tank is so ugly, but im hanging in there
My question is: how long did it take you to get rid of your algae problem if it was serious?
Also if you had a specific technique, id love to hear it.

 

ro/di water?

 

di water
nitrates normal but getting retested tonight
refugium with sump
no deep sand bed
reduced lighting and feeding
large cuc

 

oh wait sorry ro water

 

just ro? ro/di is way better IMO; makes the water more pure. that might be a problem. did you fill up the tank with tap? also list ur parameters

 

Phosphate levels? Any phosphate removal media?

 

I know I may get flamed for this, but I have to be honest ( I remember being where you are))

When I first started out in this hobby, my very fist tank became covered in GHA it was terrible, I did water changes withheld water changes nuked all of my rock, went weeks with lights out taped the tank dark, all of this helped for a week then it was back. Beefed up my CUC got algae eating fish bought a brand new RODI unit ran GFO got a reactor. REfugium chaeto mangroves. I was so close to just taking the tank down, and as a last resort I tried marine algaefix used it for 2 weeks, I only used half of the recommended dose and never had the issue again.

I am not proud of having to use chemicals, and I know this is a controversial chemical fix, but after fixing all I could I had no choice but to use it or I would have quit.

Have you tried going lights out? Do you have any pics of your tank? Have you tested phosphates? Do you run a phosphate remover?

 

Your tank is 75 gallons. What type of skimmer are you using?

 

It might be a last resort, but if it's between tearing your tank down and using this, then I would probably use this too.

This is a hobby that's supposed to relieve stress, not create it. So if using algaefix works, then give it a try.

 

Wow, I was just were you are only a few weeks ago! My 75g was like a living nightmare, so what did I do? I upgraded to a 90g. I truly believe my problem was cheap light bulbs and bad flow. I had a canister filter which was 50% of the problem now I am in a sump. If you are going to use cheap light bulbs then make sure you change then every six months not every year! Also flow is essential to keep your tank balanced. You need to have a wavemaker or cycle, fish coral and the entire ecosystem of your tanks needs it. Do everything you can to eliminate dead spots, I realize you cant get them all but your cleanup crew will get the tough spots. Also only feed what your fish can eat, sit there and slow feed them. I used to dump it all in and walk away, never cared where is went. Now I target feed everything. I hope this helps, I know every tank is different.
