Pics of 27000 litre Fish pond


Callan

Recommended Posts

Thought I would share some pics of a 27,000 litre pond I built for a friend. It is approximately 7 metres long x 4 mtres wide x 1.5metres deep and its deepest end. 

The pump and filtration used in this project was as follows:

1 x 16000 LPH pump which splits of to run the 2 x waterfalls

1 x 12000 LPH pump that splits off to two seperate gravity fed biological filters

2 x biological Filters that are hidden behing the large waterfall at the end. One is a straight filter and the second unit has 18W UV in the filter. The returns from the filters return to the pond on each side of the large waterfall

An airator was also put into the centre of the deepest part of the pond.  This helps to airate the water but more importantly helps to expel the nitrogen gases from the water and also helps keep the pond water clearer which in turn aids the filtration. 

This pond was hand dug and all the rock work was done by hand.

Couple of questions cause I have always wanted a pond lol. How much did that cost and what does he do when it rains and floods the pond?

That's a beautiful pond mate. Rock all by hand? Is that what did your back in? I moved a too big mudrock slab once and my back didn't like it either. 

 

Oz, there's normally an overflow to storm water just below the level where the pond would flood. Liner is about $20/m2 and the rest, how long is a piece of string. Keen to hear Callan tell us how much rock went into this.

Thanks for the replies.

The filters are called aBio Steps is made by Matala.

The cost of materials all up was about $7000(That includes all the equipment and landscaping rocks.

I think from memory it was about 5m3 in river pebble and about 12m3 of mudrock.

Overflows as has already been mentioned can be fitted. It would be very unusual for Melbourne to get more than 2 inches of rain

This pond because of the depth, size and filtration system could handle quite a few Koi. Depth and filtration are the most critical things when it comes to koi. Lack of depth and the koi will never gain good size in the girth.

That is why I always recommend using sub air aeration in koi ponds.

Shelving is an important key when designing ponds because it allows provision for the rocks to sit below waterlevel and it helps give a more natural look to the pond.

Kizshrimp no I didn,t hurt my back on this pond and had a few people who helped place the rocks where I wanted. It was about 6 weeks later when installing a water feature and a person helping lift it lost his grip and it partly crushed me.

Looks awesome mate....... Great work there.

You can get quite carried away with,overflows,auto top ups and circulation jets,etc But simplicity is best.

Where's the shishi odoshi :D

I love it, looks great. I want one now too lol

 

Some Goldfish and White Clouds, few plants, would look awesome hey!

He wasn't concerned when I last spoke to him and its hard to see from the photos but there is lots of rock areas under the water for the fish to seek shelter . The depth will also help and it was still to be planted although in a koi pond anything green dosent last to long.  That is why I delibrately built in beach areas which could be planted and it also allowed an area for fry to access without being eaten by larger fish. I will put up some photos of another pond I built a while ago for another friend that highlights this a bit better. The only real way to stop birds is netting. Bird scarers don't work and I have only seen one product that was partly successful. It had a sensor and when anything broke the beam it would shoot water in the direction of whatever entered the beam area.  Sometimes its the luck of the drawer but if a heron finds a food source it will continue to come back . I had to net my own ponds for this reason.

More of a hobby but I have done work at the Melbourne International Flower Show and it also is good being able to sell products and give advice to people with the advantage of having experienced things first hand. I will post a few more things I have done if people are interested.

Would love to see some more setups you've done! i tend to find thats any area which lacks information on alot of aquarium forums.

 

I am guessing you wouldnt of done any small shrimp dedicated ones ?

I did try this with glass shrimp. I put in a colony of over 300 glass shrimp and used mainly java moss, val, elodea and duckweed. I even put in a base of inert sand which is something I would never do or recommend doing in a fish pond. The thing I didn,t  consider at the time was to cover it with something like shade cloth or flywire and as a result lost all the glass shrimp to dragon fly nymph.

Thanks I will get some more on. Hopefully they will help give ideas about what is possible and may inspire a few new ponds being built...lol

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
