    They are very pretty fish, but I still don't want to raise them :rofl They look like Salmon :rofl 

    Holy smokes!  They do look like Salmon, I never made that connection.  Fish math:  I love salmon, ryukin looks like salmon, therefore I must love ryukin.  :gfish:

    I doubt that system will have enough denitrifiers to remove significant amounts of nitrate.  A trickle filter produces very well aerated water.   We have had a few people who had a zero nitrate tank with a fairly thick layer of gravel in the bottom, but the overwhelming majority of those with gravel in the bottom of the tank had to use water changes to control nitrates.

    The easiest and most efficient nitrate removal uses terrestrial plants.  Get an elongated planter box similar to this, drill holes in the bottom for drainage, place it over the tank (your hardware works here too).  Then plant in hydroponic medium, something like this.  You can use a small fountain pump to pump the water from the tank into the planter.  

    You can grow low-light house plants like pothos with ambient light.  With a grow lamp you can do herbs and even veggies.  

    I have a couple of sprigs of pothos in one tank that's coming in nicely and nitrates are noticeably lower than it was before, but that's too easy and logical, lol.  Some of our local forum members swear by the clay pellets - our hydroponic store calls them hydroton, (trade name?) as biomedia, and cheap too.  They use it in their filters from canisters, hob's and sumps and they report less nitrates than before.

    But I enjoy watching the live action of dripping water in the clear compartments, and at the end it may not make a dent in nitrates but I still have my fingers crossed.  A few people steered me to the biomedia I'm using and getting great results.  I'm using a smaller quantity of the same biomedia in a trickle filter tray of a fluval hob (crummy filter) and it's doing a good job of nitrate removal/reduction.  Less than 10 ppm nitrates after a week in an overstocked nano fish tank.  But the same media in a much larger sized canister but high flow - 900 gph did nothing.  Seachem recommends less than 50gph flow through their nitrate consuming media so I'm experimenting with less flow as I continue tweaking it.

    WOW thats a great set up now. I would love to do that in my house but my cats would try and eat them plus my 5 year old would try and grab them :yikes 

    It is cool to watch, but yeah, having it at ground level has it's hazards.  I left a cube of frozen blood worms to thaw in a plastic container by the tub and my dog took off with it.  :madrant

    If you want long commutes, consider Melbourne - and Sydney is also pretty big!

    Haha, we'll be on vacation time, but not too interested in long commutes.  Just wondering what our neighbours have to put up with.

  5. Mr floaty Oranda.  He's swimming around much more now, so we'll see if he continues to struggle to maintain his depth.  I'll be away for a couple of weeks in November, so hopefully I should have enough duckweed so I can instruct one of my fish sitter to just drop in a cupful of duckweed a day.  Water level is at about 9" depth, about 40 gallons water volume on the Rubbermaid 50.  He's a handful (size), about 105 grams.  Some more wen growth would be nice but I wouldn't mind if he stays at the current size.   My guess he is a year old.  Thai based calico oranda.


  6. Front view of the trickle filter.  I like my hardware.  :whistle

    It holds as much media as 3 of my old 2217 Eheim Classics canister filters, but I prefer to use bonded media pads for mechanical for the top layer and 2 rows of biomedia.  The biomedia is supposed to cultivate anaerobic bacteria which consumes nitrates.  I was able to keep nitrates down to less than 5ppm after a week with one goldfish, but it will take more time with 3.  It seems like it takes about half a year for anaerobic bacteria to catch up to the nitrate levels.  I do 2 x 75% water changes on the 40B, with the odd 100% monthly thrown in.  Nitrates measures about 20-25 ppm after 4 days.

    The filter is powered by a Cobalt MJ1200 powerhead with a pre-filter attached. 


  7. A few pics I snapped after throwing the tub together.  The Rubbermaid 50 is on the floor over a tarp.  If it turns out to be a permanent fixture, I'll likely have it raised a little higher on a stand.  The group of fish are on the left, I'm using an overhead trickle filter mounted on some aluminum right angles which were a perfect fit on the 40B but extrudes out on the Rubbermaid.  The spray/drip bars are running parallel to each other.

    Hi guys. Was a long, busy and frustrating day at work today! Was so glad when it was hometime

    Hello!  Do you have a long commute to and from work?  We have Australia on our bucket list to visit, such a large country we would have to do it 2 parts.

    It is something strangely satisfying in getting all the gunk out!

    Haha, for me it's a relief.  Maybe we're talking about the same thing? :whistle

    Thankfully, I'm down to just one canister now.  My love is growing for sponge filters, hob's somewhere in the middle.

  10. I figured the oranda should be making the move to a shallower tub, but it never crossed my mind to move the ranchus too since they appear to be doing fine in the 40B.  They were due for their water change in another day, so I went ahead and moved them all into the Rubbermaid stock tank tonight. I think they do enjoy the extra room to spread out their fins, that and a 100% water change.  I'll try to get some pics posted.  Thanks for the suggestions!

  11. Very nice read, I'm inspired!  I'll continue to go bare bottom on the Rubbermaid 50, I may struggle with lighting.  The led's over a 40B is no where near as intense over a black tub especially if I'm staying bare bottom with nothing to reflect the light.  I'll experiment with adding other light strips.

    I just might have to add in some fake floating lilys and flowers.  This guy is wintering his fish in a Rubbermaid 50.



  12. The were in quarantine for a couple of months in that same stock tub when I first got them.  Should have just left them there!  

    I still find it amazing how a little bit more surface area can be so much more beneficial for gold fish.  Sure the stock tub is longer and wider than a 40B, but it's not unmanageable like what you would need to support 10 adults in a glass aquarium.  It's just too bad that it looks so darned ugly sitting in the dining room floor.  I'll just have to dress it up a bit.

  13. I have a nicely proportioned juvenile Oranda that I'm growing out, he's always been the strongest swimmer of my 3 fish, his other tank mates are 2 juvenile ranchu.  Lately over the past several weeks, I've noticed that while at rest, he prefers to chill/float at the surface and when he sees me, he springs into action with a big splash and starts swimming all over the tank.  When he stops swimming, his tail end would like to float up, not quite tail over head but he's still a strong swimmer and with a couple of tail swishes he's propelling him forward and upright again.

    When he's foraging on the bottom for food, he puts it extra work to stay near the bottom.

    Would this likely be the start of a swim bladder disorder?  IIRC, he's always been raised in depth of 16" from fry and he's in a 40 gallon breeder now.  My plan is to continue to grow these 3 fish out in a 40 gallon breeder for maybe another 6 months and move the oranda into a 50 gallon Rubbermaid stock tank with a lower water level and leave the 2 ranchu behind, but if he continues to be "floaty" I can move him sooner.

    I'm happy to complete the "template" if it helps, but it's more of a general comment right now.

  14. Here's my not so brief story. Koko, I'll pass on the raffle entry, if I'm lucky enough to be selected, shipping is a bit of a hassle cross border.

    My dad bought my first fish tank for me when I was 8 years old. 5 gallon, probably 6 or so tiny goldfish.  Most promptly died, but a couple managed to survive even though this was way before I had any clue about the nitrogen cycle, chlorine, water changes and the Internet or PC's were not invented.

    I dabbled with guppies for a few years and eventually to a 20 gallon tropical community tank.  I think that original 5 gallon tank became a gerbil home.  I left the hobby for a few years and restarted the 20g tank with goldfish for my dad. He always enjoyed goldfish.  It was overstocked and 1 by 1 they started dying and my buddy said I had ammonia problems, when they died, I left the hobby for about 15 years.  Still no internet or PC's.

    I passed the 20 gallon tank to my niece as a tropical community tank.  New tank syndrome - ammonia issues, most fish died.  Just before the internet and PC's.

    A few years later, my 8 year old showed an interest in aquariums.  Bought a 10 gallon kit.  Wow - this internet stuff and all these Aquarium forums.  I got up to speed on the nitrogen cycle, stocking levels and water chemistry.  Yea!  Longer term success!  From the 10 gallon with corys and a betta to a 20 gallon with endlers and red cherry shrimp and more corys.  Fast forward a few years, Big Al's had a sale on Aquariums one Christmas, so I brought home a 75 gallon tank.  Wow...water changes took forever and I was doing daily 50% water changes for juvenile discus, so I invested in a Mag pump, Pythons were too slow.  The 75 gallon turned into a 120 gallon acrylic - big mistake.  You stare at an acrylic tank it will scratch before your eyes.  

    I thought it would be cool to try some fancy goldfish again.  I had an acquaintance that wanted to work in a goldfish farm that his uncle in China owned and he handpicked some strains for me that I never even heard of.  They all died within a year - weird diseases I was never able to figure out.  A buddy of mine says he buys imported goldfish, if they live longer than a year, he's happy.  He suspected they were hormoned for looks/colour.  I swore off goldfish.

    I've had a lot of fun breeding Tanganyika cichlids, tropheus and a few different kind of shellies were my favourite, they were either in large tanks or a breeding rack along with a SE Asian themed loach tank.  I gave up those tanks last year - just time to downsize to a few mid and small sized tanks.  Retirement and travel is not too far away.  For nostalgic reasons and in memory of my dad, I really wanted a tank of goldfish again - kinda full circle, start and end the hobby with goldfish.  I heard good things of domestic goldfish from ECR so I have a few of Cynthia's fish and a breeding colony of duplicareus corydoras, 2 of my favourite species.  I still have a couple of Rubbermaid stock tanks, I may buy a group of juvenile top view ranchu from a domestic breeder next Spring and grow those out.  But I swear - that's it!  That doesn't include a 15 year old lovebird and a 6 year old poodle.
