it's for a coppered 225gallon aquarium with way too many fish, not enough lighting and a very crappy protein skimmer.

Of course there is an algae problem. I've been doing 40 to 60 gallon water changes per week and it is progressively getting worse because they are not willing to change their feeding habits, nor their bioload.
And yes, duh, I know that it is not a quick fix, I even said that under my main statement. I just want their aquarium to look good so I can keep their account.
I suggest you give them a little lesson on "Nitrogen cycle" and how it effects the ecosystem..
A tank's ability to nitrify waste/organics is dependant on a steady ammonia production on a daily basis, and it goes like this: fish eat, then digest,then poop, which is then decomposed by microorganisms that process fish waste..
ammonia turns to nitrtes, trites turns to nitrates...which u have 30ppm of it..
Now, comes the tricky part...How are u exporting this accumulated trates????
they do not vanish like a fart in the wind does...
humans have toilets were they pee and poop, thats the human way of removing waste(lucky for us , we don't have to swim in it.)....human organs are filters. right?
back to fish: fish don't have toilets, so that means that they have to swim in their toxic waste/urine (aka ammonium).. thats were nature takes place, the natural nitrogen process helps u turn alll ammonia and waste into less harmfull nitrates..
Nitrates fuel your algea..
Nitrates have to be exported wether is via dsb denitrification, water changes with ro/di, macro algeas.microorganisms,live stock growth ect..
Chemicals dont remove nitrates, they neutralize it. making it less toxic or turning it to a different form..which still leaves u with unwanted organic/inorganic compounds. this need to be removed or it will cause nuisance algeas..
Its ovbious that the protein skimmer is not keeping up with the amount of waste produced by fish.. nor is the tank's bacterial colonies sufficient to support the bioload and high feeding activities..
U have few choices: either feed less or increase biological filtration. increase water change amount or more constantly. decrease bioload..oh and i hope your using ro water for your waterchanges..
last but not least, if u don't want to change nothing, u can do waterchanges every other day to keep up with the excess nutrients and decay..otherwise your fighting an uphill loosing battle....
