I agree, and if you poke around the website there is lots of information about sponge filters, and why they are superior.jake37 said:The only thing required for a sponge filter is an air pump and tubing. Better is always relative and as with all things there are trade offs. Also there are a large variety of hob and sponge filters. They are certainly easier to maintain. IMHO the best sponge filters are these (but shipping makes them expensive):
This is like the one I am running in my shrimp bowl but mine is much smaller. This one looks like it comes with everything you will need except for the air pump.Ssnaaiil said:
This one is a hard one to answer. Last year I bought a fluval Q1. I was so disappointed in how loud it was. I had my hubby look into it for me and he found the inside screws weren't tightened down. Once he tightened them it is almost silent. I have several no name or not well known names and most of them are fairly quiet. I set all of mine on a piece of foam to quieten them down.Ssnaaiil said:What’s a good air pump? I have a 55g and I want one that won’t be too noisy. Also would it work if I put the pump on the floor?
That one should be okay, though I don't know if you need all the fittings. Also, the first time I bought air line tubing it was 3/16". Never again. It's too difficult to get on and off fittings. Now I only buy 1/4". I can't tell from the picture, but that looks like it might be 3/16".Ssnaaiil said:
These dual sponge filters are the ones I have in my 55. I just wish Elbert would stop lifting them off and letting them drop to the bottom of the tankaltwitch said:I have a number for different size tanks and with 1 or 2 air outputs. Optimally if you have 2 outputs you would have 2 filters to feed into although will still work with just 1/2 attached. Other things to consider are how much air pressure it generates which determines speed and amount of air going through the filter. Unlike can and HOBs though, sponge filter don't really tend to generate much in the way of current based on the design.
On the subject of sponge filters themselves the one you asked about is designed to sit on the bottom - will work fine if you have a flat open area of your tank. They also make some that have one or two 'arms' that a cylindrical sponge goes on and can be attached to tank wall with suction cups. That's the type I prefer to use as they may be physically a bit larger but are thinner and don't occupy as much substrate area. I also find them easier to conceal with décor and plants. The best type I've found also has little 'cups' to put ceramic or similar media in before water moves into the filter. I really like that model (even if twice the price) as I can rinse out sponges under the tap and if I kill any bb the ceramic media will suffice until sponge recovers.
Hope that helps.
