Short for biological load, bio load is the waste accumulated in the water column of your tank. To better understand the bio load in your tank, here are a few examples:

To shop this in factories they have a coolant running over the bit, these isn't viable on a tank so the best way I have found is the fill the bit with loose ice (the White crap that builds up in your freezer) it works a treat I've drilled dozens of holes that way

Hiya. I asked Hagen themselves as I too have an FX6 coming today for my Fluval. Here is their response: Cross sectional area of 1" pipe is (25.4/2)*(25.4/2)*3.14 -> 500mm2. 16mm pipe is 200mm2. Thus a flow reduction of over a half (0.4) !!. This a major restriction and I think you will find the FX6 says don't run the filter at less than half flow as well. The issue we are having is our tank is drilled in the bottom and has 22m hoses whilst the fx6 hoses are I Beleve 1" - along with that our inline heater and co2 atomizer need the 22m hose. The awesome Fluval FX6 canister filter is excellent for fish enthusiasts and people interested in the fish-keeping hobby. The unique combination of trays allows for a variety of media enhancing its functionality and giving you crystal clear-looking water. However, cleaning your FX6 setup is also crucial in keeping the canister safe for your fish and keeping it functioning smoothly for years to come.

You will now remove the bio-media from the tray and clean it with the CANISTER water that you removed earlier. Do not clean it with tap water; otherwise, you will destroy the beneficial bacteria required for your tank. Use the canister water/tank water to clean it. The following video is an easy way to ensure your impeller is clean and will start without any problems. I'm sure with that powerhouse of a filter you don't really need to worry about a few mm difference in diameter restricting flow, or damage especially since it has "Smart Pump Technology". However, there are a few other reasons you may be experiencing bubbling. Here are the most common reasons for this problem and how to correct the issues.

Ok going to drill it - may as well do this properly - what's recommended for the pipe work once we have the proper sized holes drilled?


One of the most common problems with the FX6 filter is that after cleaning the FX6 will not startup. At the moment there's 2 plastic screw points to screw the pipes into which then connect to the tubing - infact looking at it - wouldn't surprise me if the holes are big enough once the plastic bits are off - just to work out how to get bigger pipes through and watertight! Now, you will take out the sponges and clean them with CANISTER water. If you clean this with tap water, you will harm the integrity of beneficial bacteria that are useful for your filter and the tank. Ensure that you get the gunk off these sponges and clean them with canister water. However, you can take care of the sponge baskets with clean tap water. These are only meant to keep the sponges in place. Air source too close – Similarly to issues with bubbles, you need to keep any external air sources as far away as possible. Or, create barriers between the air source and intake.

One of the main benefits of getting an FX6 canister filter is the self-starting & priming features. But what if you can’t get it going when you first set it up? The only thing you have to clean now is the canister itself. You can use tap water to clean the baskets, impeller, and the canister itself. When cleaning is completed fill the canister about halfway with de-chlorinated water. Apart from flow rate is there any other reasons we shouldn't do this - could restricting the flow rate damage the filter for example? You’ve used too much media – Reduce the amount of media you are using to ensure water can flow through the canister as intended. The first thing you need to do is shut off your aqua stop valves. It is recommended to shut off the inlet valve before shutting off the outlet valve. Once you have closed the valves, you will unplug your FX6 from the power source.

If you notice any reduction in your output flow rate, it is time to get started with cleaning your FX6 and making it livable for the fish. So, the answer to “How often do you clean your FX6” also depends upon your specific tank and its respective water conditions.There are various conditions and elemental factors that influence the cleaning routine of these filters. The tank owner should understand the different elements from water conditions to bio load before jotting down a cleaning schedule for their respective tank with an FX6. Your Bio Load Matters
