FAQ
What is the difference between 30ppi, 45ppi, and 60ppi pre-filter foams?
The PPI (pores per inch) indicates the density of the foam. Lower PPI like 30ppi is coarser and allows larger debris to pass through, suitable for heavy waste. 45ppi is a balanced option for general use. 60ppi is finer and better for cleaner water conditions with fewer fish or plants.
How often should I replace the pre-filter foam?
Replacement timing depends on aquarium size, fish population, and plant density. Typically, replacement is needed every 6 to 12 months, or sooner if the filter becomes clogged or water quality declines.
Is this set compatible with all BioMaster and BioMaster V2 models?
Yes, this pre-filter foam set is compatible with BioMaster and BioMaster V2 models including 250, 350, 600, 850, and BioMaster Thermo 250, 350, 600, 850.

I replaced the pre-filter foam in my BioMaster V2 600 after six months. The 45ppi foam worked well for my community tank with fish and live plants. It maintained good water flow and didn’t clog easily. Easy to install and fits perfectly.
Zoe Mackenzie –
Used the 30ppi foam in a larger tank with a lot of fish. It caught larger debris and kept the filter running smoothly. I noticed a slight drop in flow after a few weeks, so I switched to 45ppi for better balance.
Isaac Turner –
The set came with all three types of foam. I used the 60ppi for my low-traffic tank with only a few fish. It kept the water very clean and the filter performed consistently without any blockage.
