    Floating algae

    Me again.

    Iíve had another idea. Is my 25w uv big enough for my 7000l pond? Itís the only explanation. The water does remind me of when the uv needs replacing, clean but green but not pea soup!

    If I added another 25w uv would that be ok or would I need to replace and buy a bigger one?

    Also, have been looking at UVís. What do you think of the submersible kind? I could easily pop that in my moving bed (way less hassle and no messing with pipes etc) or should it be within a confined space like a tube for better effect?

    Use a drop in UV by any means but I wouldn’t put it in a moving bed, would not do the beneficial bacteria any good.

    Get a larger UV. More is always better.
    Get a 50w mate.

    The water has a brown look as well as green.
    Is the filtration sufficient?

    I have a 7000lt pond in full sun with only an 18watt UV, its 4 foot and clear to the bottom, as the fish grow that might change??

    I have had the floating algae seems that any treatment for whatever kills it off, only option then is for it to fall off and clump up then float around, but it improves.

    What's your pond depth and surface area in relation to volume? Maybe some shade would help.

    Hi, my pond is 5 metres long and 3 foot deep rising to 2 foot and in a footprint kind of shape. Itís shaded half of the day.

    Iíve also realised my ammonia is high (1.0] although all other readings are good at the mo. Could the ammonia be as a result of killing the algae? Iíve got air running 24/7 in pond and moving bed. I popped a E A pond bomb in Saturday to help with the bacteria too.

    The treatment could have knocked the filter bacteria back.
    The more surface area in relation to volume the more exposure to uv, so 3' down to 2' is fairly shallow, but as you have shade the should help.
    Keep a check on the ammonia, but a faster turnover rate through the filtration could be helpful.

    Hey Sez,
    I had a very bad blanket weed problem this year. I used the Blanket Answer at 100% dose. Apparently doesn't detriment the filter biology as it's an enzyme. I was told to ensure good airation though, as it uses oxygen to break down the algae. It worked extremely well, but then I had the same issue as you, tons of green muck on everything. Seive filter got clogged etc. To be expected I guess as it's doing its job. I then used sludge answer to further break that down, again a temporary overload for mechanical filters. A few days later my pond was crystal clear. Persevere with those products as in my experience they work very well. They can be reused too I believe if further algae remains, worth reading the container to check.
    Good luck with it.
    Cheers
    Tim

    Itís all gone completely pear shaped Floating algae. Iíve got high ammonia (1), so did a 25% water change (plus a bit more, woopsie!). Took another reading which says the ammonia is the same! Any chance the test kit could give a false reading?

    Plus, still got murky water.

    Why did I take up this hobby? Floating algae

    Cut back on the feeding and keep changing the water to help until the filters get going again

    Iím certain the cloverleaf has killed my bacteria, the colour of the k1 looks very clean too. We live and learn! Floating algae

    Floating algae

    Right, so have put ammonia remover in the moving bed filter as per instructions. That was about 17 hours ago with marginal results. How long do I need to wait for safe ammonia?

    On the plus side though. The fish seem happy, plenty of energy and still looking for food (but not getting any Floating algae).

    Still no shift in ammonia. Iíve added a pond bomb and ammonia remover. Nothing!

    Thereís lots of air going in and lots of very hungry unfed fish. Any tips?

    Don t worry about the fish not eating.
    Lots of fish don't get fed through winter months. Nearly 4 months. Unless we have a mild winter.
    Keep the water changes going and eventually it will come down lol.
    It takes a lot of patience. And time. My pond of 5000gallons took 18 months to 2 years to mature. I now only test once a week. Keep testing your water parameters daily. When ammonia and nitrite are zero then feed a little at a time. And when rises do the same again. All ponds are different lol. Me personally I don t believe in all this
    Pond bombs and all that. I spent hundreds of pounds on them. And they did nothing for my pond. That's just my opinion lol.
    Some people will have a different view on that.
    Like I said lots of patience. Water testing.
    And water changes. And up and down feeding. Meaning when allowed with readings. Feed.

    Ammonia is down! 0.2!

    Still green though.Floating algae

    I was looking through my pictures and found a picture of the pond in June. It was crystal clear. I canít work out why the green water now. Should I just wait for everything to die off over winter and start again in spring or tackle it now?

    That's all part of the pond maturing mate.
    Mine did the same in the early days.
    And eventually the green water cleared. I put alge clover answer in once a year to control it. Resolve now. I use. If it was happening on my pond I would just treat now. Because it's very mature. But in your case. Your having ammonia problems . So I would leave it. You may kill your bio off.

    Thanks for the advice. Iím currently look at an eazypod (secondhand) and running 2 pumps from the pond as itís 5 metres long (1 pump at each end) as I donít think 1 pump in the middle is enough.

    On my last pond. My inground pond. Before I had this pond. I had 2 pumps in the pond and two easy pods. And they did the job for 7 years. That was a 3000gallon pond. And each pod had a 30watt UV on
