green slime on glass

so i clean it off every day i never had a problem with it till i bought a pure actinic bulb so the water checks out at all zeros wondering if 10 hrs is to much light should i turn the pA off sooner like i have 4x54 watt gisemenn they are 2 actinic + and 1 pure actinic and a fiji purple what kinda time should i run them on

10 hours per day does not seem excessive to me
I run 4 x 14k T5s for 12 hours each day and 2 x 22K lamps for 14 hours

my glass needs the magnet scraper every 4th day and a credit card for the hard to get to areas once per week

is your tank getting any direct sunlight from a window in close proximity?

your test may come back 0 but often this means the algaes are using up nutrients as quickly as they are being produced


are you running a reactor with GFO or other phosphate removing resin in?
or are you using a cannister filter with a phosphate removing resin in?

if you work on reducing/ ensuring, the nutrients are as low as your test kits are telling you then your glass will go longer between the need for cleaning IME

Honestly, I don't think your problem is that bad. I clean my front glass almost daily. It's not really bad, but I get some spots that i clean up. I clean my back and sides about 1 a week. It's something that I just live with. No big deal if you have a magnetic glass cleaner.

 

its not noticable green from the front view but if i look from the sides i can see it its not bad i have no phosphate remover except a sumb and a refugium

 

I have the same problem with my T5 lights. I had those lights over my nano and had a huge algae problem, both slimy stuff and GHA on my nano. I moved my 70W HQI to my nano and the algae has died off. Now my 20G tank that had no algae problem when I used the HQI now has the same algae problems that my nano did after putting the T5 over it. I'm not sure if it's the Current USA fixture/ballast that is underdriving the bulbs or what, but it's obviously the T5 that is causing the algae problems.
