Brown green Algae

[Yahdiel91]

Hello all!

So for about a week now i been having somewhat an issue with some algae on my glass.. So throughout the day I've had to clean the glass a total of 3 times.. For some reason my glass gets covered real quick.. I been trying to pinpoint what the cause of this can be but im not having any luck.. Anything helps, please and thank you..

Tank has been running for over a year
My recent add ons to the filters and tank are purigen for nitrates and chemi pure and I've also changed my lights from current to AI 32s.. Those were added 2 weeks ago.. Exactly a week ago i added a dragon goby

Nitrates are somewhat elevated but phosphate is way elevated at 1 ppm. You are feeding a film algae bloom on your glass. I imagine new lights contributing also.
