Looking for Answers about Marineland HOT Magnum® Filters?

There are a couple of trouble shooting guides to help. If you find this is still not solving the problem, please call customer service so that we can trouble shoot further. 800.322.1266.

IF filter makes excessive noise or stops abruptly: Be sure Impeller and Impeller Module are properly installed. Also check Impeller Magnet for wobbling or wear. If evident, replace immediately. Check Sleeve, Carbon/Media Container, or Micron Cartridge for clogging - clean or replace. Rinse Canister. Always use Black Diamond Premium activated Carbon to avoid small particles getting into impeller mechanism.

IF air accumulates in Canister during operation. Inspect Air Ejector Tube. If clogged, use Nylon Cleaning Wand to dislodge dirt. Move Intake away from airstone bubbles or other air source. Also check hose connections ensure that air is not being sucked in. Make sure O-Rings and D-Ring are not dirty, damaged or worn. Replace and/or realign as necessary.

We would not recommend the HOT Magnum for outdoor use. The instructions state “for indoor use only”. There are electrical safety reasons for this statement.

Sorry, it doesn't look like we have a standard extension tube part for the HOT 250. Let me investigate if we have something else that may work.

Absolutely, most of our filtration options are for both freshwater and marine.

The HOT Magnum is about 6" wide, so I'd give yourself a good 7" from the wall in order to give some clearance. Have fun with your new filter! We know you'll love it.

Not advisable but possible. You can actually do that if you want, you just have to be extra carefully to not suck gravel into the filter.

Sorry about the problems you are having. If you are experiencing micro bubbles it would mean an air leak somewhere in the system, at the top “D” o ring, at the inlet or outlet, even one of the “exhaust” gaskets inside the filter. We will reach out separately and make arrangements to send you these parts directly.

The design hasn't changed. I'll send this to customer service so they can arrange to send you replacement clips. Sorry for the inconvience. 800.322.1266

Clarity of water is not totally dependent on the filter system. A lot of factors go into keeping a tank clear. What types are these five fish and how large are they? Do you vacuum the gravel each time you do a water change? Just how cloudy is the water? With taller tanks, quite often you will keep a slight haze to the water due to a lack of circulation from bottom to top. Dropping a filter intake down does not help this issue, but adding a small bubble wand with an air pump does. Also, sometimes you may have a stubborn bacterial or dissolved organic bloom, and using a product such as Tetra Water Clarifier will clear up the issue.

This filter is designed to hang on the back of the tank. We have a couple of different canisters that are designed to go under the tank.

You are not getting it sealed. Make sure you fill it literally to the top edge of the canister. Place silicon lubricant around the D ring, then slowly lower the cover onto the canister. Water will trickle out and down the sides, and this will give you a good seal.

Not continuously, no, as it will clog quite fast. Yes, it will clear up cloudy water, if it is due to organic matter, etc. You have a lot of filtration for that tank. How large are the goldfish, how often are your water changes, and how much are you feeding? You really should not be having cloudy water issues.

BREX

No… but other people have created their own with tubing. We may have had that part available in the past but it is not a current active part.

Yes you can we typically use a little less than a cup by volume, about 7 oz. By weight it is about 40 grams.

We don't unfortunately sell that attachment as a seperate item, it's sold as part of the Pro version of the Magnum.

I'm not sure what parts you need but they are the same. You can find them on the Buy Parts Online tab under the Magnums. Is there something specific that you are unable to find?

Hello,
You will use the Power Kleen connector to hook the intake on the HOT Magnum up to your Siphon Kleen gravel vacuum. Then would siphon the gravel bed and all the sediment would pass into the filter.

Sand that gets into any filter can be highly corrosive to the moving parts. So long as you take precautions, the H.O.T. (Hang On Tank) filter will work fine. Whenever your sand bed is stirred up, such as during tank maintenance, you will need to cut off the filter. Sometimes you can have aquatic life in your tank that will be good at stirring up the sand bed. This can be unpredictable, so if you do have this situation you may need to cover the strainer on the intake-tube with nylon material to help prevent sand from being pulled into the filter. You can also remove any extension tubes from the intake to shorten it and thus keep the strainer higher up in the tank. Also, it would be a good idea to regularly take out the impeller and clean it and also the area where the impeller fits in the motor. You can use distilled white vinegar to clean with so long as you rinse the parts well afterwards.

Hello,
This is usually related to gaskets and O-rings. Take the intake tube and outlet tube off the unit and inspect it. See if you have the O-rings on them. If you do not, then this is the problem.
Also, make sure all your gaskets are in the right position.
As for the noise, this is most likely related to something falling down in where your impeller spins. This is usually carbon from your container.
Make sure you don't have air bubblers near your intake tube on the filter, which could cause it to take in air and shoot it back out.

Hello,
Yes you could fit some bioballs in the carbon container. The carbon and/or ammonia chips should be at the bottom first. It would most likely make its way to the bottom anyway, being smaller and more dense. You could purchase a media bag at the pet store to put some bioballs in. Nylon should also work. Just make sure that you don't inadvertently damage the carbon container by overfilling it. You would need to change the carbon/ammonia chips about once a month in most cases.
