Hello Perry
I have a question for you!
How long take pro bio S and Np pro in to show results?.
Thank you

Thank you for your helpHello,
This depends on your system's ability to break down nutrients to begin with, NP Pro and Pro Bio S will help to enhance the lowering of nutrients. In some cases, they may not be enough, this depends again on your system, and it's import vs. export capabilities. Higher bio loads may need more bacteria homing surface area, and additions of zeolites, but this will be determined by your bio load. All in all, on an existing mature tank, I would imagine results are usually visual with corals within a couple of weeks to several weeks. Patience is key here![]()
