White glass how to resolve

[JerryThomas]

I have a 60cm cube aquarium with a year of life, the light is a Gnc Blu-ray plus 2 silver moon bars (actinic and reefblu) skimmer BM150 pro. as management I have the dsb. I fight with a white patina on the glasses that forms every day. I feed the fish 1-2 times a day and more the abve aquaforest line every day with the relative power food, pure food and growth (I follow the schedule that aquaforest indicate in their guide)the values are the following
ca 420, kh 8, mg 1270 po4 0.02 no3 2.5

It's film algae, scrape clean as needed.

This.

I've been in a battle with film algae for just over 30 years and have tried pretty much every scraper out there. My favorite, by far, is the flipper. Use the felt side for as needed glass cleanings and the scraper side for coralline.

I like the Tunze clean magnet...

Narrowing the focus of your lighting so that it doesn't reflect off of the glass can help.

UV Sterilization can help too.
