Hi!
I've never used a canister filter before and my filter didn't come with very good instructions. I have a PennPlax Cascade 700 and I am not sure how often I should be cleaning/changing it and what I should even clean/change when the time comes. I have a 37 gallon tank that is still in the beginning stages, it has only been running three weeks to the day.

Any advice would be greatly appreciated!

The filter media (pad, rock material, etc) should be rinsed regularly to keep the water flow through it from being hampered by debris, which is the "brown" stuff in the pad as well as visible bits of this and that. The water has to be able to flow through the media; if it is clogged the water may find a bypass around the media (some filters make this easier than others) which rather defeats the purpose of the filter.

The frequency depends upon the type and number of fish, some are messier than others and require more frequent rinsing of the filter. Usually once a month works.

The white or blue pads should only be replaced when they literally fall apart and no longer serve their purpose. Otherwise, regular rinsing will suffice. If you have carbon, it wears out and needs replacing. You don't mention plants, but in a well-planted tank carbon and chemical filtration is not recommended so these items can be removed and plain rock media used in the baskets. Rinse when you rinse the pad(s).

Thank you for the advice! Rinsing these things will not harm my bacteria colonies?
Thank you, I missed the new tank part, my apology. The filter should be left alone until the tank is established (cycle completed), say 2-3 months. Although if it becomes necessary due to restricted flow, the pad can be rinsed in tank water.

In an established aquarium there will be no issues. Some advocate using tank water (drain some in a pail when you do the weekly partial water change and use it). At first probably good advice. I have never done this, because in an established well-planted tank there is more bacteria on the surfaces in the tank than in the filter and besides plants use the ammonia more than the bacteria anyway. But if you have no or few plants, use tank water.

Just to be on the safe side adding to what's been said by Byron: I don't know your particular canister, but on my Eheim's I did this about 1's / year and I never WASHED them fully out just sorta rnsed them a little to get the 'big chunks' dirt out and some of the finer little 'brown' stuff remained (which is good bacteria). You know what I mean, not to get them sterile clean. And use NO cleaners on them please.


Another favorite of mine (cause I'm admittingly a fish tank addict) instead of rinsing them out carefully I'd use the pads for new tanks, rinse them in there (which will look ugly for the moment) that then helps the Canister to not become clogged up AND my new tanks set up were pretty much cycled instantly with the bacteria added from the existing filter pads :)

Thank you both! To Byron - I do have some plants in my tank and plan to only use natural decorations in the tank and nothing artificial (except the gravel which is white). I have a family of baby plants right now which seem to be perking up more and more as my ammonia levels go down so I definitely see what you are saying about the plants helping out.

To Angel079 - I would never use a cleaner on them, I have always just rinsed the filter pads of my pond and my old tank had replaceable pads in the filter (Emperor something or other). Thank you also for the WONDERFUL idea of rinsing them in a new tank. My 90 gallon which belongs to my mom was recently devastated (I tried to save it but was too late) and everyone died. Mom took it down so there could be some renovation in the room, but I plan to set it back up and that is a perfect idea to jump start the cycle. I've heard of doing that in other places as well but forgot about it. Thanks!

Can you take a picture of the tank (I just wanna see it lol)?
The more plants the better I always say, everybody heard about 'overstocked' tanks before, but has anyone ever heard of a 'overplanted' tank...I hadn't :)

Hope I didn't offent you with the cleaner-usage comment, I just wanted to make sure, cause I have people watch to really do the worst things to tanks over the years. But absolutely if you wanna set up a 90g, smush that stuff out in there, that will do you WONDERS and establish that 90g fast. Except for my very 1st tank I done this to all my tanks and it worked wonders (not only to cycle it pretty much instandly but I also want to say it influenced new plants establishment/ growth quicker then any chemical/ bottled stuff).

The Ehiem filters state that they only need to be cleaned when the flow is noticably decreased. Most people I've talked to clean the canister once every 3 months as I now do. I agree with the previous posts on how to rinse the bio-media. I do however replace the fine pad whenever I clean the filter because it's usually too dirty to mess with. But the course pad I rinse in cold tap water. I found that if I rinsed it in hot water the pad shrunk and water could bypass the filter. Why did I use hot water? Because snails had made there way into the filter and I thought hot water would kill them.

I see your point, but also all good bacteria will be killed using hot water on the filter media. I may or may not have posted it before, but I only done my Eheim's 1x/year.

Angel079 - You didn't offend me, even though I know that washing the pad is not something to do, I am glad you said it anyway as you never know what someone knows and what they don't. It is important to me to do this right and not let it fail. I will definitely get more plants, especially for the left side of my dritfwood as it is cut bluntly and I want to hide that.

Here are some shots of my tank:


This was before I added the driftwood. It is the best shot of the whole set up I have currently.


This is a shot from a few minutes ago with the driftwood and my new angel.

That will be very nice, you got a good piece of bogwood to build around, nice going. You need more plants :lol: of course.

I would recommend 1 or 2 Echinodorus bleheri, it is one of themost commonly-available sword plants, and one on either end of that wood on the rear side would be fantastic. It will grow to the surface, but nice lush green busy plant. And some smaller swords, like Echinodorus amazonicus and/or E. tenellus the pygmy chain sword. This latter will send out runners with little plants like crazy.

Keep us posted, if anything else comes up, just ask.

Byron.

Thank you so much! I have some of these plants, not sure what they are, that are long stems with medium-ish leaves at the ends. I put them behind the wood so they'd hopefully grow through it. I think I have an Amazon sword plant, but it is a little baby. I found an online supplier so will order as I haven't found anyone nearby that has very nice plants =[

I spent a lot of time looking for the right piece of wood and after going to many places, I finally found a website that offers photos of each individual piece they have and I found that beauty and I am very happy!

Looks good. If I may, my only suggestion would be to consider a darker gravel, if not black/gray then a natural buff colour. The plants stand out better, and so do the fish. The light gravel tends to draw your eyes to it because it is so dominant. But it is your aquarium, I only offer the suggestion.
