I know there's lovers for each product, but i've already spent a lot on this system and if possible buy only one of this powerbeads. The reason I choose these two is to keep the inside of the tank to look clean and i have some Jaebo that work great now on my current tank i want to move on to this look. It's going to be a 6 foot long tank, 28" deep and 24" high. Since it's going to be a mixed reef I'm thinking about putting the SPS closer towards the powerbeads for the flow that they need. I may supplement with a smaller pump down the road. thanks for the help.
