Hey everyone, first time posting, sorry if I'm doing this wrong. So, my pond has been very green ever since I constructed it ( 2-3 weeks ago). I have set up a filtration system but its not doing the trick. Here's the picture of the filtration, I have the water pump through large box filled with sand, rocks, and aquatic plants. Throughout the weeks, water has remained unchanged, if not, maybe even greener. Any tips would be appreciated, thanks!

Welcome @archknyght !

Green water in a new pond is very normal. Your pond is working to find it's balance and nature is doing it's part to help. Don't think of that green water (which is suspended algae) as a problem - think of it as a clue. It's telling you something is going on with your pond. Maybe it's something you can address; maybe it just requires you to be patient and give nature a chance.

I don't fully understand your filtration system. Is this an up flow planted bog filter? Or does the water run over the top of the filter? Can you explain a big about how you constructed it and the purpose for each element? I'm trying to figure out what kind of plant that is in your photos. Do you have just one type of plant or are there others?

Do you have fish in this pond? If so, what kind, how many and how big? How many gallons is it? Do you have added aeration in the form of a bubbler or waterfall? Any additional information would be helpful and pictures of your whole pond would also help.

Welcome to our forum! It can take weeks for a pond to cycle, ie bacteria to grow, plants to grow and take excess nutrients out of the pond.

^^^^^^^^^^ agree with above good questions

Here is a picture of the water flow, I think it’s a bog filter. Also, a small waterfall at end of filtration.

Not completely sure how many gallons, but it’s a 3ft width x 2ft height x 12ft length pond about 3/4 or 4/5 filled.
Not sure the names of the plants, but there’s 5 different species I think.
And yes, there are fish. Small goldfish, about 15ish of them

Well I must be denser than I thought. I am more unclear than I was before I saw this! Is this a pond or an aquaponics system?

Haha yeah, it’s a stretch to call this pond! Definitely closer to a aquaponics now that I looked it up

So why are you concerned about green water? Is your goal growing plants or fish or what's the purpose of the system?

Welcome!
You've got a lot going on there.
I wouldn't worry about the green water, it will come and go.
String algae could become a problem with clogging pumps if you have more decaying organic material than what your plants can process.
My focus would be on what the water quality is of the water that you use to replace evaporation/plant transpiration.
Try to keep your water PH close to 7 so your plants can uptake the nutrients more easily.
I've had an aquaponics system running for a number of years, so my advice is to periodically test your water for ammonia, nitrate, phosphate, PH and temperature. Your plants will tell you via fading/discolored leaves if you're lacking any minerals.
