Yes, i bet money on the reef snow, ive used similar products and they are overused in the tank adding too much phosphate.
Once a week is all i would do and thats even pushing it. Corals do perfectly fine without being fed in established systems. If anything only a few would like spot fed sometimes.
Your hurting the corals more by cutting back your photoperiod then you are helping them with the marine snow. Cyano
and light have no relationship. Cyano
is not an algae and does not require light to grow.
In my opinion feed your fish as you normally would and maintain the original 10 hour photoperiod. Keep up on maintenance and cut way back on the marine snow. That stuff is full of phosphates. And when not running a skimmer it can be really easy to create a problem using it often.
