I have the Biosmart 30000 new about 4 weeks ago. It has cleared all my green water algea problem it left me with beautiful clear water.
This week the pond went down a little due to evaporation but the water is not now clear its sort of dirty, not green, just mucky water.

I cleaned the filter out today even though the pollution indicator had not risen it was still down, and we topped up with fresh water.
In the filter was a bit of "scum" I have cleaned that off now.

Any ideas why it has turned dirty?

Hi Denise,

do you add new plants in your pond during the last time?
Do you have stones on the ground of your pond?

Hi
No I have not added any new plants, just the existing ones.
4 Water Lillies
some plants in a tub standing on the first shelf of the pond.
No stones in the bottom of the pond.

When weed dies or the algea dies off does that turn the water dirty?

2 koi spawned with about 6 days apart that was last week, all the eggs are out as far as I can see, would that make a difference.

Firstly I cannot reduce my koi
We have just done about 1/3 water change
They have not been fed on Wheat Germ

No mud on the bottom its clear

Hoping this will start to clear

My pond is roughly 16' x 10' deepest point is around 4'6" which is large enough for all my fish to go to the bottom in winter.

5000/6000 litres.

I do not consider this a small pond.

I am not feeding them wheatgerm yet I feed them wheatgerm from November - March.
They are fed a mixed feed until then.

Hello Schluser

I have had the person who installed the osase biosmart 30000 to come and look at our pond. He found that the rubber gasket that goes on the outlet under the tray had become dislodged. This was causing the water to not go through the filter sponges and collect the dirt, the water was flowing over and out back to the pond. This is the reason why also the pollution indicator was not rising.

We took the tray off the filter to empty so we could move the filter to another position and the gasket came off and was underneath the tray. The water is now clearing as it should

Schluser I think you should really get your facts right before you start suggesting getting rid of fish. These koi we have, we have had for about 13 years and have become beloved pets. What you suggested was extremely upsetting. There is nothing wrong with my pond size whatsoever after having advise from a British Koi Group.

If I had got rid of my fish like you suggested and then found this solution out, I really would be more than upset. I would seriously suggest you rethink on what advise you give on these forums.

Dear Denise,

the old opinion with 1 Koi per m³ is wrong. If you love your fishes you should also think wahts good for them.

It should be 3m³ per Koi.

And a very important fact: If you use a german forum please use an online dictionary.

More than 3 Koi´s in 6000 liters is an cruelty of animals.

Its nice for you that your water is soooo good an the fishes are so beutiful.

But this cruelty can i only condemn.

Once more:

If you don´t need my advise, don´t ask.
Its interest that any otherone here is contently with my advises

Only a few in this forum would answer in english or understand such an unsatisfactory description of the problems.

I hope i didn´t do wrong to say the truth

Good Bye (i´ll never write again to you)

Schlüser

I don't want you to write to me again as you say cruely to animals and yet you were telling me to get rid of my fishes. Goodby to Oase German. At least Oase UK was better advice. Now I will remove myself from this forum. You gave wrong advice as it was the filter that was wrong not my fish.
