Biowheel 350 Mid Level Strainer

If you open the Mid Level Strainer does it stop the bottom one from sucking? Also what are the benefits and should I always have it open? This is new Cichlid Tank with Crushed Gravel.

It doesn’t stop the bottom from sucking. Having it open will allow the water to be filtered from multiple levels in the aquarium, providing better water clarity due to superior capture of suspended particulates in the water.

Question

I have a community tank 55 gallons with a Penguin 350 filter. Where is the best place to place my filter, in the middle or off to one side.

Also is just the filter alone enough aeration for my 55 gallon community tank?? I was thinking of getting a power head, but was afraid this might be too much for the fish. I have tiger bards and assorted gourimies and a Pleco in there now. I want to place my filter where it'll be most effective. Thanks!

We normally see placement of the filter off to the side. The filter alone is sufficient for filtration but you'll find that adding a power head provides increased surface agitation which is always a good thing.

Question

cavitation noise

purchased two (2) Marineland 350 bio wheel filters less than a year ago, within the last month whenever the units are turned off during feeding and retarted one unit will always have a caviation like noise and will not go away until it is shut on and off numerous times. This went on for the last few weeks, but now it will not go away and all attempts to reinstall teh syphone, push it firmly down, add water to start it off, clear all air blockage has been futile. Operating only one unit for now, but starting to get the same symptoms on it. Whati is wrong, has the unit worn down prematurely???? Whait is the fix? Also why has one of the black syphone tubes turned from jet black to a gray tone if both units are on the same tank?

It sounds like both units are overdue for some serious cleaning. They should be removed from the tank, and totally taken apart. The impeller assemblies in the bottom middle of the filter box should be disconnected from the impeller housings, and placed in a dish of distilled white vinegar for 30 minutes. Remove any hair or other debris you see as well. Wash out the bottom of the filter box, take a q-tip and vinegar, and swab out the reservoir the impeller sits in. Do this repeatedly until the q-tip comes back clean. As for the intake tubes, small, flexible wire brushes are available at retail pet stores for cleaning this. You can also use a soft cloth and vinegar to clean the outside of them. Without knowing more about the tank and your tap water, we cannot answer the question as to the discoloration. It could be hard water deposits, a water mold, or something else.

Thorough cleaning as described above should be performed at least every other month, no matter what filter system is used.

Question

Penguin 200 LOUD grinding.

This filter starts out great for a few weeks then starts grinding. I clean it pretty regularly and I'm gentle with it. Is there something I can do for it other than cleaning it? I've exchanged it several times and it keeps doing the same thing. I've checked the impeller and it seems fine. But the grinding just gets louder and louder and it doesn't stop even after a thorough cleaning. Am I doing something wrong?

Grinding is usually due to debris such as sand getting caught in the impeller. It can also be due to hard water deposits. If you have sand, you have to either place nylon mesh over the strainer, or a piece of filter floss, spongy media, etc, inside it. If you have hard water, remove the impeller monthly, and soak it in distilled white vinegar for about 15 minutes to prevent this issue.

Are you sure that is the wheel? Could be you are hearing the impeller. In any case, there is some debris somewhere, so we would recommend removing the filter from the tank and taking it apart. Check the impeller and swab out the reservoir it sits in with a q tip. Wipe off the water spillway under the biowheel to be sure there isn't any debris or buildup there, and clean the little purple bearings. Also, make sure the biowheel itself is not warped.

Mid Level Strainer Power Filter 150

I just purchased a 20 gal tank that came with the 150 filter. My question is when or why would i adjust the mid level strainer? I have the latch on it in the up position and I have no idea if that is the way its supposed to be. I also have tiny clear bubbles all over the tank walls etc. I just started the tank almost 24 hours ago. I have all 3 pieces attached (mid level strainer, extension tube and strainer.

First, which direction the lever is in, doesn't really say much. It depends on which end of the mid-level strainer you push onto the intake tube. Bascically, if you see the slots, it is open, if not, it is closed. It's purpose is to increase circulation in the tank by pulling water from the middle of the tank instead of just through the bottom of the tube.

The bubbles are a gas reaction between the temperature of the water you placed in the tank, and the surfaces it has encountered. They are harmless and will disappear in a few days.

It is for use in taller tanks, so that you can pull water from mid-tank and bottom, and increase the circulation in the tank. To use it, just leave it open. I prefer removing the lever myself.

Depends on what type of animals you intend to keep. If you want a reef tank with mostly corals, we recommend sump filtration. If you cannot use a sump, a canister would work best.

If you are planning on having fish only or a FOWLER tank, then the Penguin or Emperor filters would be fine. You would want the media containers too. These come with the Emperor but have to be bought separately for the Penguin filters. I would then add biobeads in the containers.

Because your tank has a bar across the middle of it, I would recommend two of the Penguin 200 or two of the Emperor 280 filters, so they will fit better.

Another option would be an Emperor 280 and a protein skimmer such as the Seaclone 100.

You might want to call in so our support staff can fully explain the options. 1-800-322-1266.

Make sure the intake tube is not touching the bottom of the tank. Also, remove the impeller and impeller housing, pull the two parts apart, and re-attach them to make sure they are connected correctly. Finally, rinse out the bottom of the filter box in case some carbon came loose and got into the reservoir for the impeller.

By moving the water, the filter creates oxygen. If you are planning on stocking heavily or not doing water changes as recommended, we would highly recommend an air pump be added to the system. Otherwise, a properly maintained and stocked tank receives plenty of oxygen from a power filter like the Penguin.

Sure, other than that the canopy may not have a large enough area for the filter. Depending on the type of fish you own, the flow should be fine. I run a Penguin 350 on my 38 gallon tank, along with a Whisper 60, just because I like a lot of filtration.

Question

Can a bio-wheel filter be used intermittently, and if so what is the longest off cycle you would recommend?

We have redundant filtration in a 30 gallon freshwater tank in our den. The bio-wheel is noisier than I prefer when watching TV and the additional current it induces causes the fish to avoid the top of the tank.

Can the bio-wheel filter be safely and easily turned on and off daily? For example, I would prefer to be able to use the bio-wheel only at night, after we've left the room for the evening.

Bacteria need a constant source of oxygen and food, so turning it off for such an amount of time, would greatly reduce it's effectiveness. The filter should not be noisy. Possible noise issues would include:

- new biowheel needing to float for a day in order to absorb water
- water level too low in the tank; it should be to the base of the top frame
- filter near a bubbler of some sort
- sand as the substrate is getting caught in the impeller which should be prevented by the customer
- impeller not connected to impeller housing properly (customer should take them out and separate them, then re-connect them) or a damaged impeller. if damaged, contact our tech support at 1-800-322-1266. We would be happy to replace the impeller for you.

The fish should be able to handle the filter's flow rate. For example, I use two filters for up to 60 gallon tanks on a 38 gallon without an issue. My fish do not struggle with the current, not even when immature. So if the fish are struggling, check the water quality and/or place some tall plants in front of the filter until you can determine the cause of the issue.

Question

My filters do not self prime, what can i do to fix this?

I have two tanks, each tank has 2 penguin 350s. Both tanks are properly filled to the top, we have multiple power outages per year, and i am frequently out of town for 1-3 days at a time. When the power comes back on all but 1 one of the filters will just make a chugging/grinding sound as they try to restart, but they never do. I am afraid if i am gone for a day they will destroy themselves trying to start again, and obviously i don't want my peacock tanks without properly running filters. Am i doing something incorrectly?

Make sure the water level is always to the top of the tank in each one. Also, approximately every two months, remove the entire filter system and clean it. Pay close attention to the impeller, intake tube and area of the filter box where the impeller resides. If these areas are dirty, slimy, etc, it can impede the self-priming process. If you have hard water, soak the impeller in distilled vinegar, and swab out the area of the box it sits in with vinegar as well. Same if this is a saltwater tank.

Another possible issue, although I don't think this is the case here, is if you have any bubblers near the filtering system. They can cause a vacuum instead of a siphon.
