    Suspended fines/ particles

    Seem to have a lot of floating particles in the mid water column . What's the best way to sort this . ?

    I've just added some clay to see if that helps for now but Amy other ideas ??

    higher turnover...
    more water through the mechanical filters taking the floating bits out of the water column.

    Ive got loads of fines suspended in my water. I have a draco drum and a 20,000 vario pump running at 60%. Total water volume 12,000 gallons. I cant get rid of mine either. Ive recently introduced a lot of water cress which has definitely made a difference in my top pond area but my main pond still has considerable trouble. Best thing to address is why you have algae in the first place - which is why ive introduced the watercress. My maini problem however is so much exposure to sunlight. I have no pergola and my pond is very exposed. I dont know if I will ever be rid of the fines

    I've got plenty in mine too although been running the pump at 60% on a 20k vario. I turned off the BD air and turned up the pump which seems to have helped a bit but I think this time of year its probably difficult to eliminate them completely.

    fish are constantly pecking at the sides of the pond making a mess
    you will never get rid of it 100%

    but turning my pond over about twice and hour keeps mine to a minimum...

    I think if youre rushing the water through various bio filtrations though, your cancelling out the effect of the additional mechanical filtration. Who knows...

    Bottom drain air is usually the culprit, mine only comes on from 12am till 6am, as soon as it switches off the water has a slight fines issue but they are gone within an hour

    I installed a Tempest at the beginning of the year and this has been a game-changer in terms of suspended fines. Just saying...

    agreed,
    moving beds in particular should be run at optimum rates,
    but if you can take off the drum directly, or like me you have a large bakki shower wanting the extra turnover it should be fine.

    If it ain't getting to the bottom drain don't stress about it mate.

    My pond is full of fines at the moment, probably because my UV is being switched on and off all the time when it isn't needed as it saves a bit of electric.

    This will be worse in your case because your water was recently pea green and you needed a new UV.

    The new UV will kill the vast amount of suspended algae you have, which in turn will clump together and become fines. Give it a Month to sort itself out and for the UV to have fully caught up, then see where you are.

    Am planning on doing similar with the uv aswell mate . Thinking give it another week to do its job then switch off . Or maybe 12 on 12 off hours on a time and keep moving if to more time off to find the optimum at the mo . Granted that will change day to day with sun weather ect but some happy medium ground ?

    See what works mate.

    I can go 2 weeks with it off and no sign of green water, but as soon as it starts to tint I turn it on before bed (Economy 7), then off in the morning and just run like this for 4 or 5 days till water is 100% clear again, then rinse and repeat.

    Every year till now I've left UV on from April to November. Now realise it only needs to be on less than 1/4 of the time. But have an Amalgam now which might be helping the efficiency.

    Definitely noticing an increase in fines a day or 2 after switching the UV back on, which lasts about a Week, which as mentioned above I suspect to be the dead algae cells clumping together.

    In my last pond water from filter was pumped through UV and then into Anoxic pond which then overflowed into main pond. By the end of the season the anoxic pond would have an inch deep layer of green powdery stuff which I then realised was the dead algae cells coming out the UV, clumping together and gradually sinking to the bottom. I reckon it is these particles we might be seeing as fines in the main pond.
