Hi All,
So it has been a while…many brain cells lost….
I want to add more filtration to my existing pond which only has a skimmer and waterfall matts. The pond is only 1100 gal. Has two waterfalls. Its in full sun pretty much all day. I dont have an autofill but will find a way to install it over the pond side.
Funds are limited. I have been burned by a bad experience with a drum combi unit so not going the route of a drum again because no one professionally wants to fix them in my neck of the woods.
I am currently looking at an Evolution aqua k+ pressurized filter. I have been told by the manufacturer that i will be able to use a Periha pump on it and use an Aquasieve 2 prefilter on it (like a giant stainer basket). I wanted to originally use a zakki sieve but i see the prices went up quite high. High enough to push my out of that market. So for now, its the Aquasieve 2.
I plan on 2 retro bds which will be joined together before the Aquasieve2, then to periha pump, then to bead, then to waterfalls.
The pond is 2ft deep. The waterfalls are about 5ft high. The pump and bead will most likely sit about 1-2ft above pond water level. The pump and bead will be fairly close to the pond (within 5ft).
So i know i have to figure out total head to determine the right size pump. Do i add the length of tubing from the bottom drains, out of the pond and to the pump, into the head calculations? Or do i just calculate the strainer, bead and piping that is after the pump?
Then as a second separate question, perhaps a new thread for this…
If i oversize the bead, could i add a second pond and enlarge the pump at that time or is that just really a nightmare to do? Im thinking ball valves placed before pump and after bead could regulate flow of water between the two ponds. Would it depend on what is the min and max flow rates on the bead im guessing? Or is it just cleaner to have separate beads?
Thanks for the replies!
