i would like to transfer my bog plants into a gravel bed.i don’t have enough room to build a proper size bog filter but still wanted to run water though the gravel bed to help eliminate the Need to have plants in pots full of dirt and fertilizer adding unwanted nutrients to pond.i was wondering if there is a formula for determining gph ratio to size of gravel bed. My hope is to prevent dead spots between pots and use as much of the nutrients in the pond. Plan on adding skimmer with second pump for gravel bed. I still plan on having my current bio filter feeding my water fall. In zone 7 would my plants winter in eight inches because that is the depth of shell I plan on using. In the past I have lowered plants for wint and lifted in the spring. Wanted to use my dwarf cattails and Louisiana iris. Any ideas would be a great help thanks
