    I commented something similar the other day on a different Oz video while sharing my many thanks for how amazing the bog system works. Love it! Right now I clipped about 50 marigold cuttings, put them in notches (sliced up pool noodles quarter inch thick) to propogate them in my small bog. I do this with other plants too, basil, other reedy perennials that do not mind the water, and will help filter. You can do some serious landscape changes using this method (even peanuts will grow in water folks!). Next step is a small hydroponic system outside of the pond that will eventually grow strawberries, kale, cabbage, that feeds ourselves, and the chickens. It all starts with the small pond I have, and marigolds :) Great keys to a really healthy farm/garden.

    Hey Kev, Thought I would provide a quick update here:
    1. Rain gutters have been installed
    2. Addressed the slow drainage issues in the backyard after a hard rain (it was more than likely contributing to the water getting under the liner)
    3. I installed a 3inch drain pipe that runs under the pond liner and uses the hydrostatic pressure that builds up to force any water that may collect under the liner - I found a pond installer on RUclips who had a video on it)
    4. It poured down rain 2 days ago (gutters worked great) and it was actually a blessing as I got to see exactly where and how the water was getting in.
    I have taken some video that I will post when I have the pond all back together. Thanks again for all of your help.

    Our bog filter, which I built in may, is doing its job very well. Water gets clearer and clearer every week even while having high temperatures here. I'm looking forward to the water quality in winter. Must be crystal clear. I used a big flower pot, a layer of kitchen sponges and small and medium sized stones. Water has to work it's way up. The overflow makes nice sounds and adds oxygen to our 1200L pond. Also our pump has a UV lamp and an own small filter with sponge and stones, which wasn't enough.

      Probably the lack of plants. *Something* has to suck up the nitrogen, and if you don't have plants then algae will do that job. If you're 90% better now,. it's probably nothing to worry about further. The plants should grow a bit more and manage that final 10% on their own without you having to do any more about it.

The previous two summers it's been crystal clear. And even the first summer I didn't have the floating pond plants though I did have some other plants. I do still have shore plants, some kind of Iris type things that are in the pond and in the bog filter. So there are some taking the nitrogen out but the floating plants will help a lot.

    @8:20 re: relationship between rock size and surface area
    Smaller rocks/pebbles will have more surface area relative to their mass.
    Volume, which combined with composition determine mass, increases to the cube where surface area increases to the square.
    If you take a fist-size rock and crack it in half like an egg, the total mass of rock remains the same,. but the surface area increases across the break.
    Irregular shapes will also increase surface area- a pitted rock, will have more surface area than a same-sized one that is smooth and polished. Unfortunately this means marbles, which would look really cool as a top layer in a filter, wouldn't be very good as a filter medium.

    • @Ozponds

      I think you would need to have a flood and drain system like in aquaponics. I think the garlic bulb would root if in a constantly submerged state. But I could be wrong. One way to find out, give it a try.

    Pardon my ignorance (or don't 😜) but in the setup of a short stream with a high flow filter and a skimmer on the other end, aren't the filter and skimmer nearly identical; the water just runs the other way and one of them has a pump in it?
    I think it would be cool to come up with a barrel design that could work as either, makes manufacturing easier, keeping the same materials on hand for new builds and repairs etc. I'm actively breaking my brain over this, but I'm sure you'll have it sketched out in 5 mins 😂 It will take me a few days at least, watching more of your vids 😉

    • @Ozponds
      @Ozponds  4 месяца назад

      You’d want to put bioballs or something that increases surface area in the skimmer. Then you need to remember the skimmer pulls in lots of crap, it’s a pre filter to the main biological filter. You don’t want to much crap clogging your main biological filter. Then more filtration is always better.

    Great video as always Kev! Question for you, what's the best solution for slowing a pump down if you feel its too powerful? Currently, I'd like to slow my waterfall a little but I'm hearing confusing advice. Some say to use a flow reducer (basically a ball valve on the pump outflow) but some say this puts extra strain on the pump. I've seen others suggest using a T-piece to send some of the excess water back into the pond before it gets to the filter/ waterfall. What's your advice? Thanks!

      If nothing's changed sense you made the pond (like new stronger pumps) than the filter might just need a clean.

      It’s possible that the bog filter is clogged by build up of sediment. Kev’s videos always recommend to build the bog (be it a barrel or bigger) with pipes for cleaning. I think at least once or twice a year.
      You should go back to the bog video and check the instructions. It’s also possible that you “think” you copied but missed a detail that now is giving you the problem. Good luck! 👍

Besides the fish needing oxygen, what else in the pond uses oxygen. Friendly bacteria, do they consume oxygen?

Currently, the water is greenish, probably a foot of visibility. As part of the goal, I decided to dose the pool of bacteria. On the day after dosing, the weather turned much warmer. There was no sign of activity on the surface during the day. In the evening, the fish gathered around the cascading water and gulping. They didn’t have an appetite. The following day, I bought another pump, 2000 GPH, hoping it would help the situation. I ran the pump as is without a filter hoping the faster, more powerful cascade of water would produce more oxygen. It didn’t dawn on me the oxygen was also consumed by the bacteria, but it was too late. During the day, I used leaf blower to move the surface and to create air bubbles. At night, they still came up, gulping. Some had gotten back their appetite and came for the feeding. Overnight the circuit breaker where the pumps were running from tripped, it shut down the pumps. I got the pumps back on but I couldn’t save every one. Sadly I watched seven bodies floating to the surface. Two were saved. Ten years ago, they were tiny eggs. Each day we would meet by the side of the pond, and a feeding frenzy takes place. I watched them maturing and having babies themselves.
