  1. I have 2 fantail goldfish in a 65 lt tank. The filter is a hang on back filter but back because i keep it in my room i turn the filter off at night. Does it affect the cycle of the tank or is it ok?
  2. HOB Algae Scrubber idea

    I'm considering making an acrylic algae scrubber that'll work as a HOB, and trying to make it look fairly professional (kinda hoping I could sell 'em if the prototype performs well, tbh). I plan to use mostly opaque black acrylic, with a clear acrylic back, with LED grow lights and a reflector on said back, then a plastic mesh for the algae to grow on. I'm undecided if I should try to integrate a normal HOB filter's motor and impeller and tubing into the filter, or use a powerhead with tube attachment to attach it to the HOB scrubber. I've never worked with acrylic before, but the process of bonding joints looks easy enough. Never used a powerhead either, so does anyone have any suggestions or warnings about problems I might face?
  3. HOB filter biowheel 200

    Hey guys! Just wanna ask if there's an instance that your M.Land biowheel filter suddenly just stopped for no reason? Mine just did right now.. Just didn't hear the trickling of water on my tank.. So, I just pulled the intake tube with the impeller and replaced it back.. and voila it's working again.. Just curious if this happened to anybody who's using M.Land HOB filters here. Tomorrow I'm goin to check the impeller maybe something got stuck up which caused the sudden stopping of the filter.. Good thing, was near the tank or else the pump might have burned out on me...
  4. Hi guys. I was going to ask this in the subbies forum but I thought it might be more useful for anyone's future references to ask here. (Thanks Alex for posting in the recent thread by Koko that reminded me of this factor! ) I recently upgraded from a 40 breeder (actual gallonage held is closer to 50 than 40, holding about 49g with canister, 47g without), and now have my girls in a 75g. I did purchase another supplemental filter of an API Superclean 50 after reading about how quiet it is, plus it also has a surface skimmer which totally sold me on it. Reviews were right, by the way. It is dead silent and runs the skimmer very efficiently. Though a weak gph for a 50 gallon filter, I have zero complaints so far. I even had to slightly baffle it as it has several intake locations. My other filter is a Fluval 406 canister. Fluval 406 is approx 380 gph (cleaned monthly) API Superclean 50 is approx 200gph (rinsed twice weekly) Is this adequate for my tank, with my two weekly WCs of 90% and 50%?
  5. Hi, I recently upgraded to a new 75G glass aquarium with stand. I also purchased one of those glass tops tat the light sits on and a cabinet stand for my goldfish. Here are some details: 75G Tank 2 large goldfish (approximately 8-9" each), one is 12 years old, the other about 10-11 years old. Current fiter is filter on my old 29G (Aquaclear HOB) which definitely needs upgrading and fast. I had no choice but to move the fish and the water along with the filter media into the new tank. I typically have green water and pH problems which I can assume are due to the filter size. I currently feed them one time per day and they eat only algae pellets due to a swim bladder illness in one of the two. Algae seems to keep him in good shape (knock on wood). I would like to get feedback on what the best filter would be for this situation. I seem to have trouble with the HOB because they do not seem to fit the tank very well. Not sure if this is due to the size of the filter but I kind of have to force it to sit in a certain way for it to work due to the thickness of the frame at the top of the tank. I am open to any suggestions particularly the type of filter to go for (canister, HOB etc) and brand that will work and last. Thanks!
  6. Eheim Liberty 200 (2042)

    Most of the common HOB brands are difficulty-to-impossible to find in my area and are banned for import by non-competition agreements. Finding a HOB at all is something of a struggle. Eheim has major distributors however, and their Liberty is arguably the most available HOB in Norway. The first thing one notices with the Liberty is that it is an attractive filter. The box part is an attractive brown/grey and the top dark grey. A red dial in the middle controls the flow rate. The Liberty is designed to hold cartridges - four of them in the case of the largest filter. These cartridges are really just holsters for sponges of varying densities. One holds a carbon sponge. I took that one out and am storing it under the tank. In place of the carbon filter, I have cut a dense blue sponge to size. The centre, open part, of the filter has been filled with ceramic media. My impression from the photos posted of the larger AC and Marineland filters is that the Liberty holds less ceramic media than those filters. Once I replaced the carbon sponge, rinsed the whole filter and filled it with ceramic media (most from an old filter), I hung the thing on the back of the tank, filled it with tank water and turned it on. The hanging slot accommodates different size rims but my rim is on the wide side. As a result, the filter sits rather higher than I like. I will have to work on the tank rim to get the filter a bit lower. The lid to the filter does not snap in place. This doesn't seem to affect the operation of the filter but it does sit loosely on the top. The motor is quiet and the adjusting knob works. The intake tubes are hard plastic and do not reach far enough down the tank. Eheim sells extender tubes, however, and those are headed my way. Eheim claims that the filter does 760 litres per minute. We run two liberties, one smaller and one large. We paid somewhere in the range of 24 euros for the thing, making it good filtration for the money. I suspect that those with a choice would prefer the larger and more powerful AC filters, but this one certainly seems to do the job quietly and effectively.
  7. I'm not sure how to pack my filter. Should the contents be loose, fit (fill up most of the space), or be tightly packed. My contents include ceramic rings and a thick, dense filter floss. The problem is that if I pack it loose, it will allow the poop to get stuck in the larger surface of the filter floss, but I would have to reduce the amount of ceramic rings I have in. But if I pack it fit or tight, it would mean the poop/food would get suck on the side right next to the pump. I've included photos to illustrate. The floss in the photo below is one whole piece, It's not folded or anything. And below I used the arrows to demonstrate how the muck is getting trapped. Since I have it fit, the red arrow, , the muck and dirt is getting trapped on the side which is portrayed by the blue and grey lines after the red arrow. Or would it be better to leave it a bit loose so the muck gets stuck on the larger surface arrow and end where the blue arrow is? But doing this would mean I would have to reduce the amount of ceramic rings in. Is it necessary to put in that much? Or should I use thinner pieces of filter floss next time?
