Fluval Aquaclear xxx Series
The Fluval tray has provision for three layers. You will probably want to retain the provided foam. You might consider replacing it with GreatWave Medium Foam.
Based on the similarity with Fluval’s media we believe approximately the same amount of Biohome media would be required. Recommended Biohome media for these filters are: Standard, Plus, Mini or Ultimate. The Fluval specified media quantities and required Biohome quantities are shown in the table below:
|xxx Filter Biological Media Requirements|
|Model||BioMax Size||BioHome Required For 1 Stage||BioHome Required For 2 Stages|
|20||60 gr||500 gr (minimum order)||500 gr (minimum order)|
|30||65 gr||500 gr (minimum order)||500 gr (minimum order)|
|50||125 gr||500 gr (minimum order)||500 gr (minimum order)|
|70||195 gr||500 gr (minimum order)||500 gr (minimum order)|
|110||390 gr||500 gr (minimum order)||1 kg|
Fluval x03 Series
All models have 3 trays. Normally the first tray would be used for mechanical filtration (foam) leaving two trays for biological filter media.
|x03 Filter Capacity Based on Using 2/3rds of Published Filtering Area Volume|
|Media||103 Capacity||203 Capacity||303 Capacity||403 Capacity|
|Fluval Specified Filter Volume||1.182 lt (72 cu in)||2.216 lt (135 cu in)||3.7 lt (226 cu in)||6.48 lt (395 cu in)|
|Standard||500 gr||1 kg||2 kg||4 kg|
|Plus||500 gr||1 kg||2 kg||4 kg|
|Mini||500 gr||1 kg||2 kg||3 kg|
|Ultimate||500 gr||1 kg||2 kg||3 kg|
|BioMotion||1 lt||1.5 lt||2.5 lt||4 lt|
Note: The capacity estimates based on Hagen specifications. If you have actual experience with these filters, GreatWave would be greatly appreciative to learn how much media the filters actually hold.
Fluval x04/x06 Series
|x06 Filter Capacity Based on Published Biological Volume|
|Media||106 Capacity||206 Capacity||306 Capacity||406 Capacity|
|Fluval Specified Biological Volume||1.37 lt (84 cu in)||2 lt (122 cu in)||3 lt (183 cu in)||4.2 lt (256 cu in)|
|Standard||1 kg||1 kg||2.5 kg||3.5 kg|
|Plus||1 kg||1 kg||2.5 kg||3.5 kg|
|Mini||1 kg||1 kg||2 kg||3 kg|
|Ultimate||1 kg||1 kg||2 kg||2.3 kg|
|BioMotion||1.37 lt||1 lt||3.1 lt||4.2 lt|
Note: The Fluval X06 series includes high performance mechanical filtration. GreatWave would not recommend replacing it with the GreatWave Foam Filter Set. We would suggest removing the polyester polishing pad from the top and placing it on the top of the foam in the bottom tray.
Feedback from Bill Eisenhard indicates that the 206 will only hold 1 kg of Biohome. In May, 2015 we rebuilt two Fluval 406 filters with Ultimate media and measured 2.3 kg of media to fill three trays. All other capacity estimates are based on Hagen specifications. If you have actual experience with these filters, GreatWave would be greatly appreciative to learn how much media the filters actually hold.
Fluval FX4 Series
|FX4 Filter Capacity|
|Fluval Specified Volume||3.9 lt (238 cu in)|
Note: The GreatWave Foam Filter Set is not applicable to this filter. This filter has foam mats surrounding each tray to provide mechanical filtration. They also use a fine foam mat on top of each tray.
Fluval FX5 & 6 Series
|FX5 & 6 Filter Capacity|
|Fluval Specified Volume||5.9 lt (360 cu in)|
|Ultimate||5 kg (see note)|
