I just order #1 & #2. I like the idea that you have nutrifying bacteria in there. Can't wait to see how they work.
Hey no problem, Ken's Fish has some great prices and ships quick too. Definitely let us know about the difference in pre-filters, I'm curious since I have only used the #1.Thanks for the heads up on the price Matt. And while you were posting the suggestion about buying the different sizes, I was doing just that. I bought a #1 and a #3 so when I get them I will post and let everyone know the difference.
You may be right, especially considering the #3 uses a reticulated sponge. Now that I think about it, I use the #3 prefilters on my Magnum 350 in my plant tank and I use two of them on the Fluval 304s I have on my 125g Tanganyikan tank. The reticulated foam on the #3s are much more porous than the #1's. I can go 2-3 weeks without cleaning the pre-filter on my plant tank and I've went up to a month on the 125g. I still have #1s running on a couple of 10g tanks and they do need cleaned every couple of weeks but they are now on fish/plant tanks instead of Shrimp only tanks.As far as a bigger filter causing more resistance, it should be just the opposite. I was thinking more surface area should mean less drag unless the diameter is quite a bit larger and it has farther to suck through. And a 90% clogged large filter won't have any more resistance than a 90% clogged small filter. It will be interesting to see how long each one lasts between cleanings.
i have a penguin mini. ya know how on the end of the inlet tube thers a little cone that keeps large debris out of the filter? would i just take that off and put the sponge in its place?I just started using these sponges on all my filters, and I REALLY like them http://www.petsmart.com/product/index.jsp?productId=2752618
That is exactly what I did with my Aquaclear 20's. There is no need for the intake strainer section, the sponge now takes care of that.i have a penguin mini. ya know how on the end of the inlet tube thers a little cone that keeps large debris out of the filter? would i just take that off and put the sponge in its place?
How has the pre-filter been working for you so far? Given my experience with them I don't imagine you have had to clean it quite yet unless you just want to keep it looking prettyI will have to wait and see how long it takes to clog up, but with the bigger filter I expect it to last awhile. I highly recommend this filter.
