so i have a pool in my backyard that i calculated to be around 17,000 gallons give or take a few 1,000. and i was wondering what kind of filtration system would i be looking at for it. I have thrown in like 100 minnows to test out the water, a few koi, and goldfish. dont worry there is no chlorine left. hasnt been service for 2 years so almost all traces are gone. at least i believe so. so they have been there for 3 weeks or so and wen i first opened the pool(it has a pool cover) the water was pretty clear and u could see all the way to the bottom. But now the water has turned all green and u cant see anything. would this be algae? the pool itself is like 30" by 10" and the depth ranges from 8'-4'..so its a pretty deep pond/pool for fish

TLkmDN copy and paste that into youtube search and see it u can get in touch with this guy cause he shows his pond in his videos and it is really big and he keeps it clean he also has a video for his filtration of the pond so you can get some ideas from there and i am pretty sure he is a member here jst not sure if he uses the same name
Green water can ony be cleared by UV or a lot of plants to take in the extra nutrients. UV works the fastest, Ken could size one for your pond. Plants like lillies, Hyacinth and Water Lettuce will provide shade to the pond and keep the green water in check.
Filtration wise, a decent sized, heavily planted bog will look good and keep your water clean and clear. Also, ask Ken to see if he might have any used equipment for supplemental filtration til the bog gets ripping. A pond that is over-filtered is a good thing.

To control green water I like to go with a UV dose of 40-50mJ. Dose is a function of dwell time (chamber size and flow rate). So if you want to save energy you need a unit that has a big chamber and/or slow the flow rate through it. I have a computer program that I run for custom UV. If you have one in mind let me know and I can run the numbers for you. Your choice could range from 58W to 320W depending on the chamber. To be realistic a pond that size won't be cheap to operate but you can minimize the energy needed if done right.
You are going to need an entire life support system for something that size.
Make sure you have the budget to do it right.
Just to give you an idea. I run a 10,000 pool with 2 1 1/2 hp pumps ($350 each), 4 sandfilters ($1400 each), 750 watts of UV from Emperor Aquatics ($7300), 7 gram/hr ozone injection ($5500) and three 5 hp heat exchangers/chillers from Aqualogic ($8300).
I'm running a 17,000 gallon quarantine pool with 2 CSK3 skid set ups ( http://www.aquaticeco.com/subcategories/1189/Commercial-Filtration-Packages/Emperor%20Aquatic%20UV/0 ) from Aquatic Eco and 2 Aqualogic heat exchanger/chiller units. But it barely gets by like that.
