Green water you will get as long as there is sun shining and you don’t have a UV. If you have a UV running correctly you should be ok

Hi Wayne I have a filter drum system and have suffered a lot of water issues this year my set up is about five months old now I have about thirty fish. The filter goes through a lot of stages to balance out. My biggest problem initially was high nitrite because bio bed had not established. Got that under control pond went green and now I have crap floating about My pump was slightly to small as the guys have stated 3000lph adjustable pump is the way to go. But I have a bottom drain with a spindrifter that blasting air through jacuzzi style so I have added an adjuster on my air line and now temps are dropping I have wound the air back and noticed the crap is now on the bottom and being sucked down the drain rather than pushed all round the pond via full on air pump. I have been feeding different foods that has also not helped as they crapping bits rather than solids.

I’ll see what happens over the next couple of weeks then. Thanks guys. So much going on with the pond that I wouldn’t even have thought of until it’s cropped up.

is it a brand new drum and uv? not 2nd hand? have you checked the rubber seal between the dum and clean side wall? maybe stuff is getting through? and check bypass plates if your drum has them

It’s all brand new. No bypass plates and it’s not leaking through either.

As a short term fix for the fines could you put a filter sock that is a lower micron size than your drum onto the return to the pond with an overflow option on it?
I've just fitted something similar to the outlet of my pump fed system on the outlet of an Eazy Pod and the muck it collects is amazing. OK your drum will take out much more than my system so you can run a finer filter sock. I'm currently only using a 400 micron filter sock but the clarity different was so noticeable within a week.

the fines might well be too small for the drum, but in time as the set up matures there will be other debris in the water for the fines to flocculate with and then be of the size the drum screen will send them packing.

My bet would be on the pump being too small..A 15000lph pump may only be pushing 10-12000 ,less if an eco..This is where vario pumps come into their own .Just my opinion having seen the difference flow can make to a pond fitted with a drum

Thanks for all your suggestions but as hoped it was new pond syndrome. It’s cleared right up and so much so I can easily see the bottom. Thanks again. Spend half my time worrying. Now my latest issue is my Kohaku flashing. All parameters are all good so looks like help from a mate to catch, scratch and treat accordingly.

Sorry to drag up an old thread but Im having similar problem to the OP and doing a little research and points in this post resonated with me. I also have a new pond, about 3 weeks old, with new drum and separate bio unit (which is still maturing. I have 150ltr of Helx). We are having warm weather at the moment and the pond has started to turn green. I have a new submersible UV running that seems ok. The water is relatively clear when looking at the fish from on top, but a cloudy green from the window view. I suspect the amount of air being pushed out of the aerated bottom drain is a large contributing factor as it also disrupts my skimmer flow, particularly at feeding times. I was curious about the adjuster you have put on your air line? have you got an example of what you have used and what I could try? I also have a 20,000 variflow pump that is running at its minimum although any faster and it drains the water from the drum and bio unit - This was the case when the water was brand new and crystal clean and i must say surprised me considering I have a 4" pipe on the bottom drain and 3" pipe on the skimmer, so i cant increase my flow any more than what it currently is.

Sounds like it's just new pond syndrome. Many ponds seem to go murky a few weeks after they are up and running but usually clear up after a while.
It happened to me, happened to the op and has happened to many other people who have posted on here, so chances are that's probably the issue. I'd say wait a month or two and if it's still not cleared then could be something else.
To control the air to your BD, you can use an air manifold/valves. Then all you need to do is leave the valve for the BD fully open. Then control how much air is released on the other valve.
What drum do you have? If a 20k vari on its lowest setting is draining your bio it sounds like the drum mesh is the bottleneck.

Turned out my green water was as people have put, new pond syndrome. Cleared after a couple of weeks. I had, until the other day, just one air disc on the bottom and at certain places with it the pond there was a load of rubbish settling. Stuck another air disc in on the same airline and majority of that rubbish has gone. My pond did turn very cloudy but it’s slowly clearing.

Sounds like your mesh needs a clean with some bicarb and water or vinegar or one of the liquids sold just for drum screen cleaning as I’m guessing there’s still a film on the screen from when it was manufactured

Ive got the Draco Solum 16 which is rated for 16800 ltr/hr. My pond is around 9000 litres so not massive compared to some on here but still a good size. The pump is a jebao tsp-20000 with a variable controller. I understand the mesh is the only real point of resistance but I was just a bit surprised that im only just "getting away with it" with regards to my pump being on its minimum setting.
Well thats good to hear! I will give my glass a clean and persevere! I like the idea of additional air discs but everything is so tidy in the pond at the moment I dont think I would want additional pipes being on show as everything is fibre glassed nice and tidy at the moment
Thanks for the replies!

With my additional disc I basically T pieced it so there’s only one pipe leading into the pond and then splits into the two different discs. I didn’t put spindrifters in or anything like that when I built which was a shame but I’m happy with mine at the min. I’m going to put plastic fixed pipes in in the end but at the min it’s just a flexible air pipe.

I'm not sure what flow rate you get on minimum power with the pump but it will be less than 30% of 20,000lph then factor resistance in and you’re not even getting half the advertised rate through the drum. You never quite get what they suggest but it’ll be probably 75% plus
