  • Hi Mike

    I’ll email you, as well, but I wanted to post an answer here in case you check back.

    I spoke to our Live Deliveries Manager. You are partially right – a second canister filter is used partially for redundancy. Having a second filter is also a strong recommendation for aquarium set ups that are over 6 feet long, as it will give you more water flow throughout the tank.

    Since your aquarium is a 4-foot long set up, you would not need a second filter, unless you wanted the redundancy in case one of your filters dies out.

    I hope that helps!

    Thanks –

  • how offten to you have to change filters ( cascade 500 ) by the way I love it cleared my water in 30 mins

  • In general, maintenance needs to be performed every 4 – 5 weeks at a minimum. If you can let us know specifically what you are asking about, we can give you better information.

  • having problems with my Magnum pump filter not pumping the water, it pumps for awhile and then quits, but the pump is still running. Do i have it hooked up wrong i acts like it is getting air. Could you please help.

  • Hi Penny

    We really need more information than what you have provided in order to help you. Thanks!

  • I am thinking about upgrading from my 20L tank to a 40L. One of this things I’d like to do is get a canister filter (if it’s cost effective). I don’t know anything about these. right now I change my filter every 2-3 weeks, and each filter costs about: $3. so about $6 to $9 per month on filters… (for a 20gal which I assume will increase in price with a 40gal tank) I noticed earlier you mentioned 4-5 weeks was norm for filter replacement… How much would you say the Cascade 700 would cost in materials to replace each month? and… what do I have to get as far as materials go? one last thing… do you think that filter is appropriate for a 40 gallon tank?

  • Hi Dave, the Cascade filters are reliable and easy to work with. If you plan to stock the new tank pretty heavily or if it is a marine aquarium, I would go with the model 1000. If you are stocking lightly and do regular monthly water changes, the 700 should be fine. The cascade will have a couple of pads inside which you will gently rinse out when you do filter maintenance each month, and it will have carbon bags inside that you will need to replace every four or five weeks. How much it is going to cost you will be determined by how much carbon you run in your filter. I would think you will use 2 carbon bags each month minimum, a box of two is currently (6/16/11) $5.99 so you will spend close to the same amount you are already spending each month. The filter comes with one carbon bag and the necessary filter pads, so you would need to pick up a couple of boxes of the carbon bags and whatever your biological media of choice is to put in the filter. The bio media is not something you will replace or clean.

  • Thanks for the reply. I have a bit more of a understanding of the canister filters now, but why would the 65 gallon filter be too small for a 40 gallon tank (not sure I understand the reasoning behind that)? In general, to make sure I got it right… the pads don’t get changed… just cleaned, the carbon gets replaced, and the bio media (not sure what a good one to use is) doesn’t get changed, or cleaned… Also, by stocked heavily you mean lots of fish? I plan to have a good amount of fish (fresh water), I don’t know what’s considered \heavily stocked\. I will have no living plants, just smaler fish (barbs)… maybe 1 fish per 2 or 3 gallons (12-20 total), and maybe 1-2 plecos.

  • Hi Dave, for a freshwater aquarium you will be fine with the model 700. Manufacturers do not often get it right in my opinion, on recommended tank sizes. One example of that is the filtration on the 265 gallon aquarium I have set up, according to manufacturers specs, I should just need one of the filter I have installed on it but I am running two. If you were going with a marine setup rather than freshwater, I’d say don’t go less than the model 1000, for water flow purposes as well as for giving you more physical space to run different types of media that a marine tank may need that a freshwater aquarium really doesn’t. The model of filter you choose doesn’t just rely solely on the size of the aquarium, but also is determined by the aquarium configuration.

  • ok… so my plans may have changed a bit… still a fresh water, still a canister filter, but now I’m looking at a 50gal. decoration will just be fake plants, gravel, maybe some logs, and structures, and some fish of course… do you think the 700 would still be sufficient for this setup, or should I get the 1000? I don’t want to have to do water changes every week or anything, so if the 1000 would keep it cleaner longer, I’d prolly go with that one, but if there won’t be much of a difference between the 700 and 1000 I’d rather just keep the 700…

  • The 700 should be fine for you. Just keep up on your monthly water changes as you should.

  • Nice research and comparison in a chart format. I especially like that you identify the inlet diameter. Also nice would be to know the number and size of baskets designed for each model – this would help in planning for media when you haven't seen each model.

  • i have a 75gallon tank that i am currentley turning into a saltwater tank whats the best filter and skimmer to get for the tank? need HELP lol

  • Justin, I sent you an email. Sorry to take so long to respond – I didn't see your comment!

    Thanks –

  • I'm working on getting a 180g aquarium and I've researched different canister filters. I have an Eheim 2217 on a 125g Malawi cichlid tank and I like it. I'm torn between Eheim and Rena products for the 180g tank. Any comments?

  • Rachelle, both brands pretty much do the same thing. There is a price discrepancy between the two. If you are comfortable with the Eheim brand, I would suggest that one. Otherwise, you can try the Rena. We do have a 60 day guarantee, so if you try the Rena and don't like it, you can return it for a full product refund within 60 days! has the details for our guarantee.

  • A great concept – to match and compare the qualities listed. However, a list of this nature should be updated. For example, I did not see Haydor -sp? , or Fluval FX5/6 and a few others. The best deal of all – not indicated – would be the Sun Sun and Aquatop CF-300, 400 and 500. Now they ARE power players without the price!
