Pond Pressure Filter Pitfalls: Hidden Dangers and Limited Benefits

Pond filtration is very important and pond pressure filters are good filters but they just aren't made fit all pond types. Pond pressure filters are simply too small and overrated for the amount of water that they can actually handle...
This video is about why the size of pond pressure filters lets them down...

I'm on my third pressure filter in three and a bit years. The first one, an online shop own brand, came with the house and I blew the UV due to having no clue what I was doing. I bought the second, a different own brand, and I was never convinced the UV worked and it was a PAIN to replace the lamp. The clasp was also really difficult and my pond vitually emptied over one night (fish all survived and it was a good opportunity to clean out the gunge!). I did my research next time, bought bigger again and went for a Laguna Pressure Flo. I finally saw the bottom of the pond for the first time late summer last year, not long after I installed it. UV lamp is easy to change and the hose attachements are SOOOOO easy. It's also easy to see when the top is locked in place. My learning from this is that cheap really isn't economical when it comes to pressure filters.

I love your honesty to what works and what doesn't...

Cheers appreciate it

Well done for remaking this one, great advice with maximum subtlety.

Thnx for the the comment

Thank you for this video. I have a Blagdon Clean Pond Machjne for a 3,000 litre (660 gallon) pond and works well. I chose the large version and as you say, the box says over 75cm deep in shade and no fish will be sufficient for 13,000 litres. I chose this one because with over 75cm deep, in full sun and with fish says can handle 4,875 litres (1,072 gallons). However as I now inherited a few koi as well as having some of my own, I now need to upgrade to a larger one so I can have excellent results, not just working well. Really appreciate your videos which give a balanced view. Keep up the great work.

[@thep0ndman]

Glad it’s working thanks for the comment

I’m thinking of upgrading to a pressure filter for my 175 gallon pond but not sure what brand or size to get. I’ve heard Bermuda is a good brand. I usually stick to a rule of 100litres per fish so I’ve got 7 fish in nearly 800 litres. Got told if I had a really good set up could be more flexible with the stocking ratio. Very informative video

[@WillGoodlet]

Thanks for the clear info, very helpful

[@glennvbusse-mx6si]

I have only just come upon your videos and am rather pleased that I did. Not sure if you can help us but we have an LPG/ wood fired hot tub made of polyethylene that holds 800 L aprox 180 gal water height being aprox 80cmand when not in use it has a lid that fully covers the tub - we would love to get some type of filter so that we don't have to waste our water too often by having to emptying the tub frequently. I have tried most pool/ spa stores but have had no luck and they are not very interested in helping so I was thinking of using a pond system - so far our options could be the Oase Filtral 1500 UVC ,(NZ$522) or the Jabao LPH Pond Fountain pump (NZ$196) or using a PondMax Evo Series pond pump (EVO II NZ$285) or smaller combined with a pressurized filter not sure which one LOL. I would expect that we would need the water to cool down first before using any type of filtration system. We were thinking of using the tub as a water feature with a fountain when not in use during the off season. Your input would be much appreciated. Cheers Glenn from NZ.

I am tapping into a ground spring for drinking water. Would this be something that could be used for this purpose? Thanks

[@Crazyforkoiandgoldfish]

Im the first year of my pond I did have a oase filtoclear 16000 litres It was ok when my koi’s where Amal but this year I did have a good grow and the filter start to straggler and upgrade to a EAZYPOD and is ok now 😎👌

[@thep0ndman]

Glad you’ve got it sussed! Thnx for the comment

[@nielsdelrue7242]

Hi i have a 2000l pond end was looking for a presure filter I can buy a bigger moddel but than i have a bigger uv lamp is that than a problem ? For killig the good bacterie to fast ?

[@rebekahheywood7050]

I want to buy a filter for keeping my pond clean as of yet i dont have fish (may add some cold water but no KOI) its a feature pond in the middle of the lawn sunk into the floor full sun, I have no where to hide the boxs within 2.5 meteres which filter/pump would work best for 4500 litres a box or pressured and how do i make reach?

[@MrBretonian]

Thank you for this. Will a heavily planted pond assist in the draw back of the pressure filter? Both my pond run pressure filters, but both well planted.

[@thep0ndman]

Yes it will to a point a lot of the debris ge caught in the plants so it doesn’t all make it to the filter. But we like planted ponds more natural the better good health advantages and keeps nitrates and phosphates down

[@maxcloutier5285]

A decade ago, I installed a similar unit on a small pond. At first, it did a good job, eventually, the filter clogged, imploded and busted. I recovered filter media beads during many years in my pond.

[@paulwilliamson1069]

I have a 20000 litre all pond solutions pressure filter on a 3000 litre goldfish pond it works ok but in the summer i have to clean it twice a week

[@Giuseppe-fv9dr]

I have been investigating this one for about 4 weeks or so. The biological and mechanical actions look good as well as the 18W UV and no doubt that the sponges are easy to clean with the handle. The handle on the Blagdon Clean Pond machine is starting to leak on mine unless I place it in an exact spot on the turn. Will continue to look at my options and appreciate your comment.

[@thep0ndman]

Thnx for the comment

[@orlovszki]

So, it must be filled with fishes. And in this case a pressure filter is not the best option. Skimmer and sieve filter as first stage makes miracles

[@paulwilliamson1069]

About 15 adult goldfish and due to breeding About 20 yearlings but now in the winter only cleaning it once every 2 to 3 weeks

[@ninabailey5208]

Hi im currently running an oase screenmatic 90000 in a 12500 l pond but now looking to add a bakki shower would these pressure filters be ok to run one of these as im guessing this would be doing half the work because of the screenmatic working alongside it,i would have loved to use the screenmatic as a prefilter but i cant achieve it,the pond is pump fed to the screenmatic,i hope this makes sense many thanks great vid.

[@ninabailey5208]

sorry i should add that i really want a waterfall in the pond to introduce natural oxygen with surface movement rather then just relying on air stones so bakki shower would give me that plus the benefit of added filtration,im just a bit confused about how to set it up 😫

[@lukehaycock93]

Thanks for the video. If I’ve got a 175 gallon pond and would like to get an external set up any recommendations? I’ve heard Bermuda are a good brand. I tend to keep to a basic rule of 100 litres per fish but I’ve been advised that I could keep more if I get an external set up? At the moment I’ve got 7 fish biggest one is about 8 inches which is a shubunkin.

[@thep0ndman]

Hi the rules abit silly. We did a video on how to calculate the correct size filter for your pond on the channel. Basically go as big as you can afford

[@lukehaycock93]

@@thep0ndman ah ok that’s interesting thanks so if you have superb filtration set up then you can be more relaxed with stocking levels? I always hear people argue about correct stocking levels. I’ll certainly consider going as big as I can afford. Thanks

[@bungabening3530]

Hi Darren, thanks for this video. I'm a Brit living in Indonesia, have just moved house and acquired an empty 8000 litre pool. We've put a few goldfish in it but I want to try keeping a few koi so your videos are proving useful. Bearing in mind what you said about pressure filter capacity I'm thinking of getting a 30,000 litre model and a 10,000 or 12,000 liter per hour submersible pump (total head is only 2m). How does that sound? I'm thinking 1.5 inch or 2 inch piping but not sure how to calculate which would be best.

[@thep0ndman]

Yes that will work fine. It’s more an issue when people add 30 koi and feed 5 times a days. Goldfish do not produce that much waste and people don’t tend to over feed either so it will work well. A few plants added will work wonders too, just ensure you plant them properly, we did a video about that too cheers

[@bungabening3530]

@thep0ndman Thanks for getting back to me. Not just goldfish but a dozen or so smallish koi for starters. I'll take a look at your video about plants. One of the advantages about being in Indonesia is the variety of plants available

[@FortitudoMuayThai]

Just got myself a 20,000ltr oase pressure filter, my pond is 2250ltr im going to be putting afew koi init, hopefully this is enough 🙈 as i dont have room for anymore filtration. What you think?

[@thep0ndman]

It should be fine people have issues when the over feed so keep it low and try not to have unhealthy fat koi

[@BobPORTER-bu6pu]

Ive aquired 3 or 4 pressure filters over the years. I still use 3 of them as pre filters for two oase filtomatic filters. I dont use the sponges on the pressure filters but ive filled them with Warden commercial bio balls.( Aquadabra sale them now as Aquateck. ) I use the back wash system to clean them The Filtomatic filters are supposedly an all singing all dancing filter system, but in my opinionion there is a lack of biological filtration, so thats why i converted the pressure filters. It works for me

[@thep0ndman]

Many thanks glad it works thnx for the comment

[@karafarm3023]

In my opinion, the most efficient electricity is a gravity filter with a slight difference in the height of the sump chamber water and pool water, However, this will take up more space

[@thep0ndman]

Thanks but filters don’t use electricity only pumps and uvs do cheers

[@crajumeira]

So a good big n beats a good small one

[@thep0ndman]

🤣

[@martijn6505]

Did oase ask you to take the first video down? In the other video you showed the issues from this filter.

[@thep0ndman]

Just a general video on pressure filters across the board thnx for the comment

[@hypefaith]

So informative than you

[@andrewsmart3268]

It's common knowledge with any pressure filter that whatever the litre says on the box that is only based on an empty pond soon as you add fish specially koi that is halved because koi produce alot more waste that keeping goldfish

[@thep0ndman]

Common knowledge 🤣

[@SystemScandll]

Our pond is about 800+ L. Just bought one of these oase 12000 filtoclear + 5500 Aquamax pump and I thought it's going to be over kill. I would hope recycling the water that more than 3 times an hour via three tiers, should be more than enough to clean and oxygenate properly

[@thep0ndman]

Should be ok always keep fish stock levels low, don’t over feed, keep plants and everything will look after itself

[@Cyberbobxxxx]

Had a 20000 pressure spin filter, load of crap would never buy one again. Terrible!!

[@thep0ndman]

Sounds awful…
