Hi Dave,

What type of fish are you keeping at 7.8?

Is your light on a timer? For how many hours is it on now daily?
For how many hours was it on before you changed the photoperiod?

Does sunlight hit the tank at any point of the day?

The phosphate absorbers take about a day to start becoming effective.

What type of ornaments, rocks, etc are in the tank?

The silk plants may have something in them from the manufacturing process thats encouraging algae growth. Are they commercially made & designed for aquariums?

Let's get to the bottom of this!
