Help with Cyano in a 450 gallon reef

[jayare]

Hello all,
I'm helping clean and take care of a 450 gallon reef tank. The tank is just getting over a fight with hair algae, and now the cyano is starting to kick in. Any suggestion on what to do to help fight this?

The tank was using 2 Berlin Skimmers (yes, I know way under powered, and they were producing jack). The owner installed a 6ft tall AquaMedic skimmer last week, so I think this should help out. The bioload is heavy, but the tank has a good amount of LR. All water is RODI and feeding is minimal. Also, I've suggested uping the flow in the tank. Currently I believe his turn over rate is only around 5X. I would like to get this up to around 20x over the next month.

I've been just blowing the red slim off of the rocks with a turkey baster to keep things looking nice. What else shoud I do? Any chemicals out there (red Slime Remover) effective? Phosphates test untracable, and pH and Nitrates are good.

Couple of other things: he currently has some sort of Mechanical Filtration Reactor on the tank. Shoud this just be pitched? Also, he sump has bioballs in it, which he has started to pitch periodically. Should these just be pitched altogether and switch the sump to a chaeto factory?

Any and all help would be appreciated.
Thanks,
Jesse

Crrecting the problem like higher flow and a better skimmer is the right thing to do.
I have used Red Slime remover and it works great to get ridd of it quikly.It does NOT hurt any fish corals or inverts.Many people around here will tell you not to add anything but to only fix the problem but most of them have not actualy tried it as I have.Do it you will be happy with the results.You have to realy mix it well in a cup of water first and the water will turn a slight yellow color but will go away dont worry.Yoy might need two bottles as they are small and only dose like 100 gallons or so.

I've used Red Slime Reomver on my 40 gallon tank before with decent results, so maybe I'll give it a shot again.

Also, what would be a good solution for some flow? I'm looking into the new VorTechs since the tank is acrylic, and getting powerheads with the cords into the tank kind of sucks with only a couple of openings on the top. Otherwise, I thought about a couple of Tunze on a controller.

I used Chemi-clean a month ago and had no problems, lps, sps, fish, inverts. Stand by for a 24 hour job with a major water change at the end, but it returns it to pristine.
