Hi
If got a 100lt marine tank and struggle with green alge. Do water changes. Salt ratio is fine. Nitrates good. Everyday is cleaning of sand and so on. Still a bit new on this tipe of tank
 
Well, if you have an algae issue then you have a problem with nitrates and phosphates. The algae will provide a 'false reading' if there is so much in the system that it becomes undetectable.
What is your water source for water changes and top off?
There are articles in the articles section about algae battles, but basically it will be a long drawn out battle to solve your issues at hand. It will be large water changes with ro/di water. During these water changes manual removal of the algae needs to occur.
To put an understanding of this, if your nitrates were 100, a 10% water change will only take your nitrates to 90. Then they go up again and down by 10% again the week after. Large water changes, 50%, will take that number down to 50. Then continue with additional water changes will take that number around 40. Then a 50% to 20...so on.
