In my goldfish tank, where I have 2 of them, 29 gallon. I have an HOB filter. It has room for 2 b sized filter cartridges and I put one in at a time. It also has a bio wheel, but it stops spinning a day or two after I put a new cartridge in! They are also very dirty when I change them out. I can't afford to change them every 3 days, is there anything I can do? Any cheap filtration?

My other tank doesn't get nearly that filthy, and I don't change it often because I have plants and instead of carbon use a pillow stuffing looking type thing in the cartridge.

The filter is supposed to be good for up to 45 gallons. *sigh* I do a weekly water change of about 5 gallons on both tanks, sometimes ill do another in the middle of the week for the Goldie's. once they outgrow the tank I'm giving them to a pond, although one of them was my first fish ever ;(

I think the actual problem may be over filtration. With the filter being designed for more water than there is it's taking more bacteria and waste out of the tank than a filter suitable for your tank size would.

Don't take that as setting stone, I just wanted to contribute. I'm sure someone who knows a lot more will contribute shortly ;)

I use the marineland bio wheel I use filter fiber looks like pillow stuffing and I use I call them fill your own carbon bags works well change one side at a time if you only have one side change half of the filter fiber it is a lot cheaper than the cartridge but you will have check it often it gets clogged kind of quick and cleen the impeller often couse the filter fiber sometimes get colied around it it is a lot more work but a lot cheaper one other thing you can do that is less work is use the marineland rite size blue filter pad and cut it to side and same thing fill your own carbon bag or put one pad down then the loose carbon on top then a 2nt pad on top the bag has on the marineland rite size filter pad has a picture on how that work those are the only ways that I know of I hope i was able to help you .

That's what I do for my 20 gallon. Does it provide better filteration? And my smaller tank has the fill it yourself things but I haven't found one in the b size.

And actually it is recommended for go,dfish to have a stronger one since they produce so much waste :) it's 29-45 so it's not over..

That's not how filtration works :) it does not take bacteria out of the water - there is no bacteria in the water to be taken out. Bacteria lives on the biofilm that forms on surfaces in the tank.

5 gallons a week is not a large enough of a water change for a goldfish tank. I would start by upping the water change to at least 50%.

Yikes, a week? I did that daily for the 20 gallon when I had extremly high nitrates. Phew. Hmm... 50% of 29 rounded to 30 would be 15 gallons, so three buckets... I just hate carrying the bucket around and messing up the decor.

I think there is not much difference in filtration if any at all the fill it your self carbon bags don't have to be size b I think what you are tanking about might be a little different the ones im tanking about are like a kind of canvas drawstring bag kind of like a filter sock but a little different I don't know if you are aloud to post a links on here if you are I can get one from ebay or amazon to show you the price and what they look like if you can post links here I would gladly post you a link with what im talking about hope this helps

Instead of buckets you could rig up a large siphon hose to drain and fill. I made one.

It's a 15 foot siphon that I attach to the inside of the tank with a suction cup, and drain water into my bathtub or out the window. Then you can either fill the tank with a hose (mine is right next to my window so that was easy) or rig up an attachment to your faucet, so the siphon screws onto the faucet to fill the tank.

Would make water changes much quicker and less of a hassle :)

Or you could buy one of these. Amazon.com: 25 Foot - Python No Spill Clean and Fill Aquarium Maintenance System: Pet Supplies

I thought about buying one before :) but that's like $40! So... Urg... And also I condition water before putting it into the tank. That's my dilemma.

Condition for the entire tank volume & hose it in. If you rinse those cartridges in dechlorinated water you can reuse them, I'd slice the side, pull out the carbon & add some floss. I've tried putting cut down sponges & such into the bio wheel filters, the pump can't handle it.

You've got a lot of fish for a 29, goldfish are messy. Though the filter is rated for 45 gallons I'd be going double the tank size with that stocking. Consider adding a second filter, AquaClears are more suitable for mechanical filtration.

Well you say that you replace it every 3 days but can't you just rinse it in tank water and put it back in?

Also, I can't say how great it is... Python seems to have better review. But there's an aqueon water changer on amazon for ~$23. You can also make your own for probably cheaper with just a bit of work (think of it as an investment though in less future work!). Or at least siphon out the dirty water into a toilet (that's what I do) or something like that -- saves you from carrying the dirty water, at least.

Hmm.. Ok I'll look at it.. It's the clean water that bothers me more :p lol.

How many people use a python here?




And I don't change it every 3 days, it gets dirty that fast though. I just leave it in... I know, that horrible. Mm... I can try rinsing it. What's wrong with tap water?

I think you can get a drinking water hose (or garden hose if you aren't paranoid about chemicals... Most people seem okay), for about $10. And a sink adaptor for maybe $4 at a hardware store.

Oh of you're asking how to stop it from gettin dirty so fast then idk. But tap water has chloramines and chlorine that apparently kills the good bacteria if you use tap water. I'm not sure whether or not you can use clean conditioned water though...

That sound more convenient for the wallet! Especially the sink adapter part. Not sure about the hose though. :)

You can rinse the filter media in clean conditioned tap water, been doing it for years. Been filling with a hose for years as well, to the point that I ran hot & cold water to my fishroom.

Disinfectants in treated tap can do a number on the nitrifying bacteria in the filter media. If you're newer to this it's not something you want to play with.

Ya, but. The gravel should have enough, right?

Honestly, I've priced it out to build your own and you don't really save anything (compared to the cheaper water changers). Pythons are more expensive than the aqueons. Even at $40 for the python, you will be thrilled to have spent that money after the first time you use it.
