are they DE or mogul bulbs? what is the history on the tank? thats the big question i think.

Nutrients + light equals algae growth. The more nutrients, the more algae. I would check your water quality.

Do you use RO/DI for makeup and water changes.

If your TDS reading is 42 on RODI water, you need to change the filters. (likely all of them). If you have a phosphate test, you might run the test on your makeup water.

so you think it isnt stripping all of the stuff out of the water causing it to produce phospates.

Could be. Just trying to help find the source. TDS on RODI water should read zero.
