Thanks gain for answering my questions - I totally appreciate it. I did find a link about the filter online and I am reprinting what it says here. I think I will switch the Eheim canister I have for my 100 gallon tank over to the 40 gallon and get another newer one for the 100, which I am going to start cycling this weekend.
Installing your Filtration System
Maintaining your Filtration System
- Attach strainer (and extension tube, if necessary) so that strainer will be no closer than two inches to the aquarium gravel once the system is hanging on the aquarium frame.
- Hang system on aquarium frame. Be sure aquarium water is at or above the "minimum water level" indicated on the system's motor assembly.
- Once the system is properly in place, plug filtration system into outlet being sure to arrange a drip loop with the power cord,
- Squeeze "Start button" on Timestrip and place it in compartment on filter hood so that the white area shows through the window. The bottom of the white timeline will darken approximately 30 seconds after activation. Important: If bottom of timeline does not darken, then the Timestrip has not been activated and you need to squeeze the button again.
Changing the Carbon Filter
When the Timestrip in the filtration system's hood has turned completely red, it is time to change your filter. Note: It is important to change your carbon filter when the Timestrip indicates it is time to do so because that means the carbon in the filter has reached its capacity for removing toxins.
Cleaning the Bio-Scrubber™
- Open the system's carbon filter access door and lift carbon filter carrier.
- Hold carrier above doorway for a few seconds to drain water. Then invert carrier to a 45-degree angle and carry to waste bin.
- Squeeze carrier handle to drop dirty carbon filter into waste bin.
- Insert clean carbon filter into carrier (tan-colored floss should face the front). Drop carrier into system and close filter access door.
- Squeeze the start button on a fresh Timestrip and replace old strip in compartment on filter hood so that the white area shows through the window. The bottom of the white timeline will darken approximately 30 seconds after activation. Important: If bottom of timeline does not darken, then the Timestrip has not been activated and you need to squeeze the button again.
Note: Do not dispose of the Bio-Scrubber unless it is damaged.
The Bio-Scrubber is a permanent part of the filtration system. It is not meant to be replaced or disturbed. If your Bio-Scrubber should ever become clogged as evidenced by restricted water flow or water flowing over the top of the Bio-Scrubber, then follow the procedure below.
- Remove the system's hood and remove the Bio-Scrubber.
- Gently rinse the Bio-Scrubber in a bucket with aquarium water. Do not use soap or any other cleaner. Note: Do not remove the beneficial bacteria growing on the Bio-Scrubber. These bacteria turn toxins into harmless compounds.
- Reinsert Bio-Scrubber and snap system hood back into place.
Anyway, guess I have an answer
The internet is a wonderful thing Thanks for being here LOL
