  1. I never used fish to grow with duckweed, I use old tank water (source of minerals and nutrients) and some aquatic plant fertilizer. I feed a cupful of duckweed daily, so it's not too small if you feed duckweed pretty regularly. It's likely once your goldfish gets a taste for duckweed, none will last in your tank!
  2. Glad it started working again...nothing more frustrating than a filter, especially a canister that refuses to run. My guess is that it lost it's prime - perhaps air made it's way through the hose or canister body during the service That would explain the rattling sound until water filled up the chambers again.
  3. If your water is naturally low in KH, your pH will likely be low too. If you fishless cycled your aquarium, the whole nitrogen cycle uses up a lot of carbonates which would naturally lower your pH too. Have you done a water change after the cycle? Do you have fish in the tank? So it is important to know what your KH and pH readings are out of the tap. Your pH readings a day later after your water has had a chance to outgas would also be useful to know too. When I use baking soda, I use enough to raise my KH to about 6 dKH, pH rises instantly once the baking soda dissolves. Your dosage will vary depending on your KH level. For me it takes 2 tablespoons in about 40 gallons of water.
  4. I love the look of acrylic tanks, but there's not much love in return! I look at it funny and scratches magically appear.
  5. With my tanks with a thin layer of sand, I paint the outside bottom of the tank a flat black. When sand does get pushed aside, it still looks quite natural and without any glare too.
  6. I'm a big fan of sand too! Not more than a half inch thick works for me, so it's quite easy to stir up and siphon the waste.
  7. No problem, I hope you can find a good fix. If you go the eggcrate route, I meant to say that the edges of the cover should just fit the inner lip of the top tank frame. On most tanks, there should be a recessed lip to hold a hood/canopy or glass top.
  8. If you are able to find some smaller pieces of white light diffusers, I call them "egg crate", they can be cut to size to fit perfectly over the edges of your aquarium with a pair of tin snips or diagonal/wire cutting pliers. They are sold in sheets at your local home hardware place i.e. Home Depot, Lowe's. You don't need that large a sheet, so maybe you might have friends and family that have pieces leftover from their diy projects. It won't help much with evaporation, but you can get creative with it and cut it to your tastes. This gives you an idea what it looks like. I still prefer glass tops, but for a fishroom, it's a less costly option. https://www.amazon.com/AMERICAN-LOUVER-Eggcrate-Louver-ALUMMIL2448-2PK/dp/B06XGZ42J3/ref=sr_1_23?crid=49SA2QUAHX2H&keywords=egg+crate+light+diffuser&qid=1567698976&s=gateway&sprefix=eggcrate+light+%2Caps%2C218&sr=8-23
  9. What kind of lights are you using? Some of the old incandescent lights casts a yellowish tint, but if the lights are good perhaps a background to take the edge of the yellow tint or some of the newer LED light strips can highlight other colours to neutralize the yellows. In some of my tropical fish tanks, I use almond leaves that release tannins in the water. Water is still clear, but it has an amber tint. I don't really notice the difference over time.
  10. Congratulations! Positive thoughts your way sent!
  11. Wow! Nice looking job, looking real solid. And...I think there should be a utility sink beside every fish tank!
  12. Anaerobic bacteria thrives deep in the filter media - pores, cavities and channels. The aerobic (oxygen loving) bacteria thrives on the outside - that processes your ammonia and nitrites. If the flow is low and slow enough, the aerobic loving bacteria will still get their oxygen, the anaerobic bacteria will get less flow and oxygen as mulm blocks the path of the flow and the media structure naturally impedes water flow. Just from personal experience. I had high flow canister filters, pumps, hobs and nitrates stayed the same. By finding a way of slowing down flow and or different, adjustable filters, it got what I was looking for. Let us know how you do with the Biohome. I had to take a hard swallow when I priced it out. I immediately thought, oh I will just do more water changes, but our water supply is great. I dont have to deal with nitrates out of the tap. I have learned from this forum that goldfish can get the oxygen they need from the surface area of the tank. Wider, lower heigh tanks are ideal, it just seems like a natural fit with goldfish.
  13. That would be an interesting experiment. I dont know what is the capacity of your trickle filter, but It may do the trick. Your tank capacity is 240 litres? What is the output of your powerhead? I have a similar setup and it took some tweaking to get it working the way I like it. I think the Pondguru guy did a youtube video on modifying a trickle filter similar to yours for denitrification. You may want to search through his videos. With denitrification, you need much more media volume than regular filters, the proper type of filter media and I mentioned that flow rate seems to be the key. One of the better box filters I found to help supplement your main filters are from a distributor of Poret filter foam in North America, you may be able to make or buy something similar. I am using it in a couple of my tanks to help with denitrification. http://www.swisstropicals.com/filtration-shop/betterboxfilter/
  14. 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.
