    Diy Sponge Filter

    There will always be a slight GPH loss when using a powerhead with a filter, but the extent of the loss depends on the relative size of the sponge and how clean the sponge is. A thick sponge will restrict the flow more than a thin sponge. Sometimes I go a bit too long between cleanings of my sponges, and I get a noticeable drop in water flow. If I were designing a sponge filter, I would size it so that the powerhead sits near the surface of the water, and the sponge extends down to almost touch the bottom. A given surface area can only house a finite number of beneficial bacteria, so there is some minimum surface area that is necessary to process the waste in your tank. I remember seeing the numbers once, but you'd have to know the surface area within the sponge as well as the waste output from a goldfish in order to figure out the official minimum size you'd need. I try to avoid being overly technical, so I judge how much sponge filter is necessary by comparing the sponge to the amount of media that fits in a HOB filter.
  2. I know that every part on the Eheim is replaceable. I've had to replace the handle clips before, and it is a reasonably easy fix
  3. I agree with Daryl. I've seen reverse-osmosis systems listed on Ebay for a good price. The water in Cambridge tastes like water out of a lake. Even after 3 months, I was not able to drink it...
  4. There are things in the water that we don't usually test for, so nitrate levels are the typical indicator for water changes. My 50 gallon tank is planted and keeps my nitrates at 5ppm, but the pH slowly changes over time, the kH slowly decreases, and a lot of water evaporates, so I have to do a water change eventually. Thus, despite the fact that my plants are controlling my nitrate levels, I still do large water changes every week or so.
  5. I don't have any Raingarden fish yet... I tried to order a beautiful male telescope from Steve last summer, but he failed the pre-shipping inspection due to injury (apparently injured during breeding), so they had to refund my purchase. I'm glad that they have such high standards for quality, but I really wanted that fish because of his unique coloring, and he would have made an excellent mate for my moor.
  6. If this tank has a fish in it, and you haven't just done a water change, then those numbers definitely show that the tank is cycled.
  7. Thanks for correcting my filter arithmetic
  8. It sounds like your setup is approximately within Koko's standards for filtration and stocking (to follow the rules exactly, you need an other 100 gallons per hour of filter flow, but you may be okay for now ). So now everybody is going to ask for photos. Photos are always welcome and, of course, are often worth a thousand words. You are posting in the correct section for getting help/advice/suggestions. However, should you feel the need to show off, we have a dedicated photo section for showing off fish and tanks: http://www.kokosgold...-photo-section/
  9. My water line is at the base of the trim. I have powerheads at each end of the tank, with their outflows aimed across the surface, and they stir up the entire surface of the water without splashing. Thus I get reasonable oxygenation with no noise.
  10. There is probably enough junk being dumped into the river that your fish water won't make a difference. However, I'm not sure that the EPA will agree. How close is the creek to where you will be dumping the water?
  11. I've become fond of using powerheads attached to sponges. It is inexpensive and effective, and might work if you can find a good suction-cup mount. Have you considered a canister filter? You may be able to fit the intake and return pipes through your lid, but it may be difficult/expensive to obtain high flow rates.
  12. You can only edit for a short time after posting. Maybe it's dependent on whether somebody else has read the post? I'm not sure. But it's usually pretty short. It seems like the tank's advertised volume is based on outside dimensions, and if you filled the tank completely full. Nobody fills the tank COMPLETELY full, that would get messy real quick. I think that I determined that my 50 gallon tank has like 45 gallons in it. Maybe.
  13. I've not used the Fluval, but I have used several internal filters, and currently have two powerheads with sponge filters on them. The Fluval internal filters seem quick and easy to use, but bulky. There are other internal filters that are smaller and hold more filter media. The Fluval has thee good features: the media cartridges are easy to remove, you can choose between three outflows, and it's attractive (despite its relative bulk). Unless you need all of these features, I would look at a different model or manufacturer. Just my informal review (opinion) Hopefully somebody here has actually used one and can tell us about it.
  14. It looks like everybody has covered all your questions, so I just want to reinforce what was previously said about the new tank: You can set up a new tank and transfer the fish and filter over to it right away. The old filter will transfer its beneficial bacteria, and can be run alongside a new filter (I've run 4 filters on a 50 gallon tank before). Be sure that the new tank is the same temperature and pH as the old tank, and you can transfer the fish over right away. I don't know what method you use, but when I am moving fish around, I prefer to scoop them into a plastic bowl rather than use a net, in order to minimize risk to the fish. This requires sticking both arms into the fish tank, and can be fun Good luck, and P.S. I find that goldfish of similar sizes tend to school, but fish of noticeably different sizes tend to ignore each other.
  15. "stock tanks" are tanks used for watering livestock. The plastic ones are incredibly durable (inch or two thick) and come in various large sizes. Many have a drain in the bottom that is perfect for connection to a filter or for water changes... thus they make great fish ponds. Some Koko's members have small clay/terra cotta pots inside their tanks. I know there is some concern about chemical contaminants leaching into the water, but I don't know much about the subject. Some clays are apparently safe.
