  1. This is a nice forum. Lots of people willing to help. There's many ways of raising fish/goldfish, so choose what works for you and your finny friends. I've had internet friends where they had higher levels of nitrate levels out of the tap, that is a tough situation to be in. They attempted to do the same thing too in order to control the level of nitrates. Our salt water friends have been doing denitrification for years, either through deep sand beds, live rock, media reactors or through their sumps. It's not new science, but not very common with fresh water fish. Maybe it's just easier to do a water change to reduce nitrates, but the salties have to dose marine salt and other additives to bring water back up to ideal conditions.
  2. Here's a start. Long video, maybe your patience level is better than mine.
  3. This is just based on my personal experience on "de-nitrification" or filtration to reduce or eliminate nitrates, so your mileage may vary. I experimented with different forms of filters for nitrate reduction. I got the best results from overhead trickle filters and air driven corner/bottom filters. Canister filters and most hang on the back power filters were not as good. The key here is flow. I get the best results if the filter filters less than 50 gallons/190 litres per hour. The bacteria that consumes nitrates lives in anaerobic or very low oxygen conditions. Deep sand bed filters are an old school example of this. Lower water flow encourages anaerobic conditions. So the filters that worked for me were the ones that I could control the filtration flow. The choice of media is important too. Standard filter wool will likely not work for you - water flows too easily creating an oxygen rich environment. Media designed for this ie. Biohome, Seachem deNitrate, Marinepure Cermedia has a ton of deep channels that encourage anaerobic conditions so it gives you a better chance of cultivating nitrate consuming bacteria. Also the volume of filter media required for denitrification is likely a factor too, more than the regular volume of media needed to eliminate ammonia and nitrite. I don't have a standard answer as to how much, I tinker around until it works. Complete denitrification in all my tanks took about 6 months. I'm not familiar with Juwel equipment, I think it's only sold in the UK? "Pondguru" has interesting videos on Youtube, he sells Biohome filter media in the UK. I would start there for more info and research. Other than that, other people have had success with Pothos clippings or hydroponic systems - that might be something that you may want to explore too.
  4. Unless you're using gravel or larger pebble pieces for the look, I prefer using just sand. When you stir your pebble/sand mixture when gravel vacuuming, eventually all the larger gravel bits will settle on top as the finer grains of sand trickles below. I've never had a problem with dead spots in sand. I can see it happening in deeper sand beds that are not stirred up, but I use a very thin layer of sand and stir it up every water change - no chance of sand every compacting. I paint the outside bottom of the tank black, so when viewed from the top of tank, it looks very natural. Are you growing your anubias and java fern on stones or movable objects? If you are, you can get away with a much thinner layer of sand, just enough to cover the tank bottom.
  5. Cool looking tank. Pygmaeus corys would be great if you can get them, IME much more outgoing than other dwarf corys and so darned cute. Unlike other dwarfs, they will swim bottom and mid level and not constantly hiding. I think a 15 gal tank can handle a nice shoal of ember tetras too as another option.
  6. I use to love canister filters, but I went through a few until I found a couple that i was happy with. But when you run a few too many tanks, the higher maintenance schedule starts to wear thin. I have several classic Eheims in drydock, they worked so well and so efficiently, I hope they can find some service but for the unsuspecting. lol. I shoot for denitrification in all of my tanks. Zero or near 0 nitrates between water changes. My overhead trickle filter does that, the simple good old corner box filter too for tiny tanks and my latest filters, the Better Box Filter invented and sold by Swiss Tropicals can do that too. The Better Box Filter is an improvement on the old box filters, higher media capacity, easier to clean and a good poret filter sponge on top. The nice thing with all these filters are that I can control the flow rate with air valves. HOB - are probably the most versatile of the bunch. My favourties are the are the Aquaclears and the newish Seachem Tidal Filters. Most tanks have a combination of an HOB and some sort of a sponge or box filter system.
  7. Thanks for sharing! Cute, beautiful fish. Good luck with growing out the orandas, they should be spectacular! What variants were the parents?
  8. Maybe it was my source of crushed coral, but it was too finicky for me. It does have a shelf life, so you have to stay on top of it. But my main buffer is baking soda for goldfish, I do use Seachem Alkaline buffer for my tropical fish tanks (smaller volume). Both are good.
  9. Congrats to all the winners, I am so fortunate too! ECR has such nice fish, it will be hard to choose. Thanks to ECR and Kokos for making this event fun!
  10. Haha, had a good laugh at some of your Instagram posts, I need to spend more time there...
  11. Hello and welcome! I never ventured much into the social media side of the hobby, I like doing my research and picking through old topics in forums and picking up valuable pointers here and there. So for me, social media is not as useful to me. My brick and mortar fish store has a presence there, but they are a business and the exposure is good. I will a point in checking out your Instagram page. I hope you continue to have much enjoyment in our goldfish hobby, I have seen too many of my fish buddies leave over the past several years.
  12. Completely new tank? Oh no, after all the work you have put into this one? If it is all about the goldfish, that is understandable. The internal filter and tank would probably be excellent for smaller tropical fish that would not be as messy as our little piggies. If you are looking at a new tank, it would still be workable to get the HOB filter now and have it running in your Juwel tank and it will be fully cycled and easily transferred over to your new tank. I always buy more filter than I need for a current tank, giving me the option of if I do upgrade the tank, the filter just gets transferred to the new tank with no issues and worrying about maintaining the bio cycle.
  13. It is a nice looking tank! I do like the idea of an HOB replacing the internal filter. You could probably insert more media with a good sized HOB and it will likely be easier to service it too. Is your internal filter removable? if it is you would have gained more swimming space. I cannot tell from your picture, but does your tank come with a dark background? Perhaps an HOB can be mounted on that side if there is one, and the only thing you would really notice is an intake tube and perhaps the outflow of the HOB filter.
  14. My fish enjoy bug bites too, in different sizes and formulations: https://www.fluvalaquatics.com/us/bug-bites/
  15. Wow, beautiful! Congratulations - I hope the catalog was complimentary.
