Prevents debris such as dead fish and plant material from clogging the intake by distributing suction evenly down the length of the sponge.
Maintains the biological filtration when the main filter is changed or cleaned.
Vastly increases bio filtration capacity over many standard Aquarium Power Filters (HOB filters).
Can be used with most power heads as a temporary or permanent filter in aquariums, isolation tanks, holding tanks, etc.
Prevents small or baby fish from being suctioned into the main filter
Prevents anemone and invertebrates from being suctioned into the filter.
Traps larger waste particles, mechanically cleaning the water
Can be used with most outside filters, canister filters and power heads.
Increases depth of HOB filter intake by up to 6 inches (15 cm.) for better over all circulation (it is still recommended to have more than one independent filter or at least a separate air stone for best over all filtration results).
Increases longevity of filter cartridges (often by 300% +) of filter the Filter Max is attached to by removing a considerable amount of debris prior to entry into the filter, this in turn saves money with less filter cartridges purchased and less clogging hassles (especially with high efficiency filters such as the Rena Smart Filter).
Includes three adapters for use with various main filter intake tubes.
Easy to clean. Just rinse and squeeze in used tank water
Can be used in the vertical or horizontal position.
Available in three sizes
A must for HOB (hang on back power filters), such as Via Aqua, Penguin (older models), SunSun, AquaTech, Aqueon or Whisper (or most others with round intake). As well the Filter Max fits most canister filters such as the Eheim, Via Aqua, Fluval & many others.
These pre-filters retain and improve biological filtration even when HOB filter media is changed. These pre filters also extend intervals between filter cartridge changes, saving money (and contrary to some opinions, improves the efficiency of cartridges by removing more coarse debris before entering the filter, thus allowing the cartridge to remove more fine debris)
Entire Filter Max recommended for best results, although use with sponges only is possible on some filter intakes
Excellent to use with CO2 generators to better diffuse CO2 into the aquarium (you use these filters to diffuse the CO2 bubbles into the aquarium)
Please note that in each Filter Max suggested Flow Rate we state "Actual Flow Rate", this means the flow in gph or lph that the filter or pump actually produces with all filter media & head pressure added.
Example; the Filstar XPS is Rated at 250 gph, but its actual flow rate is 142 gph as normally configured on an aquarium.

Sponge size 2 inches by 2.75 inches
Tank size: up to 20 gallon
Surface area: 30.6 sq. in.
Suggested Actual Flow Rate under 130 gph
Sponge size 4 inches by 2.75 in
Tank size: over 40 gallon
Surface area: 49.4 sq. in.
(Note: the Filter Max #3 differs from the #2 not in sponge size, but in design, allowing a higher flow rate)
Suggested Actual Flow Rate over 200 gph
*Filter-Max 2 & 3 Combo:
A combination of the Filter Max #3 and Filter Max #2 to get the best of both filters (fine particulate filtration and higher flow rates).
2x Sponge size 4 inches by 2.75 in
Tank size: over 60 gallon
Surface area: 80.9 sq. in.
Suggested Actual Flow Rate over 200 gph
The Filter Max Adapts to most all round intakes (& Teflon tape can be used to make a more snug fit on less tight connections), here are the sizes of the adapters:
1-1/4 OD. 1-1/4 ID
1-1/8 OD, 1 ID
5/8 OD, ½ ID
7/8 OD, Ύ ID
All adapters can be connected to either the outside or the inside of the intake pipe for your filter, whatever works best.
There is not one round intake that I personally have not been able to connect a Filter Max together with, and I even once (with much modification and Teflon tape), connected a Filter Max to a square intake on an Emperor filter (please do not purchase a Filter Max thinking this will be a simple DIY modification to adapt it to a square filter intake, as it is not)
PLEASE NOTE that all these parts are initially included with your Filter Max, these are only "spare parts"

HYDRO POND FILTERS For Hydro Pond Filters, follow this link
Hydro Pond Filters are essentially extra large Filter Max Pre-Filters
Excellent for use in High Flow Aquarium Sumps, Central Systems or similar.
Often, even with all the variations available with the three adapters plus the elbows provided with the Filter Max Pre-Filter, the filter does not fit as snugly as desired.
The above picture displays a SunSun HBL-501 Hang On Aquarium Filter where some Teflon Tape was added to make the fit more "snug".
Here is another picture displaying the use of Teflon Tape for a more secure fit to a Via Aqua M200 Filter Skimmer attachment:
A Filter Max can also be mounted to a power head/water pump such as the Rio Plus 1000 pump shown in this diagram/picture BELOW using the parts that are provided by both the Filter Max and Rio Pump (a Filter Max #3 is recommended, although the #2 can work as well).
This application works well for using your Pump to run other devices/filters such as a Fluidized Sand Bed Filter.
