  1. No problem, I keep a journal of my test results and set up. These were my last Nitrogen readings as of Saturday taken just before their weekly water change: Ammonia 0ppm Nitrite 0ppm Nitrate approx. 20ppm The only tests I do regularly are for Nitrate and TDS measurements. From mid Oct to until 2 weeks ago, nitrates were barely measurable with the API tests. Colour barely registers with the API test reagents so I picked up a Salifert nitrate test kit to confirm my results. That tested 2ppm before the weekly water change. So it was a bit of a surprise that nitrates were higher and the only variable is cleaning the filter housing and rinsing the biomedia the week before (old tank water). We have a few local hobbyists tinkering with biomedia geared for denitrification and most users experienced dentrificaton to within 6 months. I have similar results in 2 other tropical fish tanks, but the goldfish are my heaviest nitrate producers. When I was on vacation for 2 weeks, they fish were fed only duckweed. I left a barrel of prepared water, so several gallons were changed out several times a week. When I came back, nitrates still measured 2ppm. I target nitrates to 10ppm or less between water changes - either through water changes or filtration. Sorry for the food confusion. My regular feeding regime is a surface skim of duckweed with an empty yogurt container in the morning. An 1/8 tsp of NLS Algaemax early afternoon. That's usually gone within half a minute. Occasionally another helping of duckweed late afternoon and either an 1/8 tsp of NLS Algaemax or frozen bloodworms in the evening. With this schedule I don't see any symptoms of floatiness. It's only lately when I push it a bit and try to hand feed the ranchus some Repashy Solient Green and the Oranda manages to steal a piece here or there. The other foods listed in my prior post were fed in the past before the Oranda experienced greater floatiness symptoms. When I was testing which foods that produces symptoms, I would include a feed of that food with just duckweed. If Mr Oranda develops symptoms, I go back to all duckweed for several days until the symptoms disappear. When I was experimenting with different foods, I would feed the food for 5 consecutive days and if symptoms develop, that food would be on my no go list. My experimenting was during the period after I came back and when nitrates consistently measured 2ppm. So from that testing, duckweed, NLS Algaemax, frozen bloodworms were agreeable to the Oranda. He swims and forages well (for an Oranda) and has a surprising burst of fancy goldfish speed when he spies food. Obesity? I'm not sure, to my untrained eye, they look proportional from the day I first bought them, about a year ago now. I have a friend that owns her own fish store and the medium to large goldfish imports she brings in looks heavy to me. Most fancy goldfish pics I see in fish shows do not look right to me.

    Happy Holidays

    Thank you! I wish you and the family & critters much happiness over the holidays and a joyful, healthy New Year!
  3. Ooops...sorry I missed this. All the fish are doing fine in the Rubbermaid 50. So of the foods that I have, the ones I can feed without any issues are duckweed (about 1/2 a cup twice daily), New Life Spectrum Algaemax, frozen blood worms. Repashy Solient Green, NLS TherA+ pellets, Paradigm Herbivore freeze dried crumbles, frozen PE Mysis shrimp cause floaty issues in Mr Oranda. The 2 ranchus are still smiling without any problems. I try to sneak in some Repashy food for the ranchus, but one of them is a slow eater, likely the eyesight isn't very good. It takes him several passes to take in any food and quite often he misses. That gives Mr Oranda enough time to swoop in and hoover up the forbidden food and sure enough, the next day I usually find him floating at the surface. I have a 2" round air stone that produces lots of fine bubbles and he seems to like to hover directly over the air bubbles. Yesterday, I found him floating upside down and when he saw me, he righted himself pretty quick. For water quality, I've just started using a Wondershell. A large one for 40 gallons worth of water, it seems like it should last me about 3 weeks. I have enough to give it a good trial so we'll see how the goldfish do with that. If they do well, I may start using that to raise some baby ranchu next summer. I cleaned out the filter housing and rinsed the bio filter media with old tank water, my de-nitrifying bacteria didn't seem to like that. I was consistently getting less than 5ppm readings of nitrates a week between water changes for the past 2 months and now it's back up to 20-25 ppm after 7 days. 😡 Back to multiple water changes a week now. 🙄

    Is my girl pregnant?

    I've been cultivating my duckweed in a 40 gallon breeder tank. I didn't think that 3 medium sized goldfish could make a dent in my duckweed crop...I was wrong. They'll gladly inhale all the duckweed I offer it.

    New to Koko’s

    Welcome, Nice tank and fish! Does it take long to do your maintenance on your tank? I had a couple of 6 footers going and though I miss them, it was unreal how much time I had on my hands when they were actually gone. Forums aren't what they used to be anymore, this is a nice place to be. The "other" had some real hardcore hobbyist/breeders in the past that posted combative posts but if you can wade through that stuff, it is useful for research though. But no warm, fuzzy feelings.

    I did not realize how good we have it here then. Sure, lots of mom & pop fish stores have closed down, we're down to a handful all within about 30-45 minutes driving distance away. My LFS is pretty good, 10 min away, I can look at her fish list and order away. Most are coming from overseas breeders for regular and tiny tropical fish for nano tanks, selection is pretty good. But at least you were able to get a few emeralds - they're already doing the cory dance for you! They would prefer to school with their own kind, but they are very tolerant of any other cory. They wouldn't necessarily school and shoal with them, but they wouldn't swim away from them either.
  7. When I try to get rid of my duckweed, it rises from the dead and it invades the tank again. I'm using the 40g breeder that my goldfish were in, filled it up 3/4 of the way with old tank water, an airline w/o air stone just to keep the water from getting stagnant. A few live daphnia and a splash of Seachem plant fertilizer weekly. 5 weeks later starting with just a few duckweed and it's thick like pea soup. Help - I can't keep up! I have an old LED light over it for probably 15 hours a day. When they get there twice daily scoop of duckweed, I'm sure some daphnia gets ladled out too.
  8. Thanks! Took me awhile to cultivate mine. Now I have a thick layer growing in a 40g breeder tank. I started off with a small portion of duckweed and sterilized it with a misting of Hydrogen Peroxide followed by Vinegar. Much of the duckweed didn't survive, but a few did and now I have way too much.
  9. Capacity of the stock tank is 50 gallons. I have it filled up to about the 40 gallon level. Separate question. I ladle in a cup of duckweed in the stock tank a couple times a day. The fish are at the surface slurping/mouthing at the duckweed until it's all gone, could be like an hour each time. Would that promote extra gas in their system nibbling on all that duckweed?
  10. I've heard of Wondershells and we have 0*dKH. I rely on baking soda to keep my a KH reasonably high enough to keep the pH stable, so the water does need changing if just to replenish carbonates used during the week.
  11. Thank you! You have very soft water too with little buffering capacity too? During the winter I do have to watch out for oxygen supersaturation too with larger water changes.

    So sorry to hear, especially this time of the season. Prayers and well wishes sent!
  13. Quick update, Mr Oranda seems to be swimming ok with duckweed and NLS Algaemax. He is more active now with a combination of higher temperatures and foraging for NLS pellets. I just started introducing frozen blood worms to the tub yesterday. The wens for all 3 fish are coming along, but they could be "poofier" if that's such a word, so I'll continue with the blood worms unless there's floatiness issues developing again. If the bloodworms work out, I'll experiment with frozen mysis shrimp. Just took a nitrate reading. It's been a week since a water change. I can't even get a nitrate reading with the API test kit. I tested with the Salifert test and it comes out to 2ppm. Exactly what I was hoping for. I just have to resist letting my water change schedule slide, I still want to do 50% water changes weekly but it's nice to know that I have a cushion if I'm not able to do a water change.

    A cory breeder that I follow calls the fry catlets. So appropriate!
  15. Back from vacation - sorry this thread is more like a journal. Fish appears fine, my 40 gallon duckweed tank is just thick with daphnia and duckweed. I hope they don't grow tired of duckweed. I know I would. Took a nitrate reading, less than 5ppm, not readable on the API Nitrate test...just barely orange. I'll test with the Salifert test another time. I had my fishy helper do occasional 3 gallon water changes with prep'd water whenever she felt like it, 30 gallons were used up while I was away for 2 weeks. Nitrates were going up about 5ppm daily for the past 6 months that the filters were setup and I needed 2 x 75% weekly water changes to keep Nitrates on the low side, so it looks like my biomedia has completed the denitrfying cycle. Now I'll probably drop down to just a 50% water change weekly just to keep water fresh. Mr Oranda is ok after 2 weeks of duckweed. I started introducing some NLS Algaemax 2 days ago and he still seems fine and not really floaty. Not really too active either until I drop in some Algaemax and he goes bananas. I increased temps to 75*F hopefully to get him more active and swim more. I'll introduce some new food this weekend if he's still good with the Algaemax.
