Hi everyone, first post...
I've always had great luck with forums when I have questions, however I have posted this same line of questions to laguna support to help me figure out what I need to do...
Here goes...
long story short:
I've had an pump that for a while now I thought it was broken, turns out it just needed a little cleaning, but since then I replaced it with a power jet 1600. which might have been a little undersized when taking in consideration the head height of the waterfall and the flow at the top was significantly less than I anticipated. So I wanted to know what was the GPH rating on the the old pressure flo 10000 (WG10000). Logic would dictate that would be 10000 gph, but to me that sounds a little unreasonable that I had a pump that strong before I changed to the 1600, anyhow, I can't seem to find any documentation or flow chart for this particular model published... I was hoping you can help me out so I can figure out what the flow at the head height should be. I also have a little giant pump that's documented to do 3500GPH at 10' head height... But I think that's a little much for my application... I have ~35ft of hose and about 2 90 degree bends and the waterfall stands about 5ft over the water line. Doing a bucket test, I managed to fill a 2gal bucket in 9 seconds, if my math is correct, that's 800 gph, the total pond volume should fall between 1600-1800gal. I've also recently purchased a pressure flo 2000 filter and read in the manual that the water pressure shouldn't exceed 5.8psi... not sure how I can calculate that... Is there a way I can tell that I don't exceed this pressure? I'm using 1.5" ID tubing... Any help figuring all this out would be appreciated... Thanks,
short story long:
I've inherited a pond when I bought this house with 4 large koi's and many smaller gold fish's just over 5 years ago.. Having 0 pond experience figured how hard could it be..., A few years gone by and we had one very bad winter where I just couldn't keep the snow off the top of the pond (this is before I learned about the floating heating element) and my 4 large koi's died... Ever since then, its been downhill...
The water turned extremely sludgy, algae is out of control, the undergound tubing sprung a leak and I was loosing water... So I got the shovel out, moved some dirt replaced the tubing and redesigned the waterfall (it was too close to an apple tree anyways), then my pump died (or at least so I thought until last week when I randomly tried it again and it worked), since I thought it died, I got a new pump, a Laguna Power jet 1600... the pressure wasn't the greatest, but it got the job done... that's when I learned about head height... and also noticed my UV filter wasn't working... When I cracked that open I had a broken bulb, so I replaced it, but still doesn't seem to be working...
So I bit the bullet and bought a pressure flo 2000 pressure filter/UV light to replace my foam pad oasis biosys gravity filter. Also picked up a used skimmer box that came with a Little Giant WPG-96-WP pump (I was simply using a bottom feeding pump earlier)... After I figured out my head height to be between 9-10ft (35ft of tubing, 2 90 degree bends and ~5ft above water line) according the flow chart of the little giant, it would roughly be 3500gph for 10' head. I think its a little much since I believe for an ~1800gal pond I should be aiming for ~900gph flow rate (correct me if I'm wrong). This is when I tried that old Laguna pump I original had (model WG10000, can't find any documentation on it). I did a bucket test with that and managed to fill an 2gal bucket in 9 seconds, which is roughly 800gph if my math is correct. The manual for the pressure flo 2000 filtersays that the water pressure shouldn't exceed 5.8psi... I have no idea how to calculate that...
Anyhow, thoughts on all this? I know its a learning curve... I've learned a lot already, but I know I have much more to learn... and I kind of enjoy this hobby now that I understand it a bit better...
Thanks,

Thanks,
Maybe on purpose so we keep buying new...
