I was wondering if anyone can tell me why after i i do i large water change on my oscars tank the water turns green, like an algae bloom. I treat the new water and after the tanks get a bloom and i have to treat it with algae remover then its crystal clear.

If you live in an agricultural area, your water might be high in nitrates, phosphates, or algae growing chemicals.
I had the same problem that I fought for months.I finally just added a UV sterilizer.No more green water.
I never understood the whole wattage theory? I've a 7w on a 400 gal pond and it cleared it from nearly black water in two days! I paid $68 and it came with a pump!
Higher wattage can kill smaller items IME. A lot also depends on your filter system. If you had a 100g/ph filter and a 100W UV in a 20G, it'd work the same as a 9W. But if you had a 1000g/ph filter with a 9W in a 200G. it wouldnt work very good.
I may not be very clear but if you have a high output, you need a higher UV IME. This may not be the case. Just works for me.
