Fluval ClearMax is a targeted phosphate- and silicate-removing polymeric media designed to produce rapid, measurable drops in phosphate levels for algae-prone systems. Compared with broader adsorbents such as Purigen or Boyd's Elite, ClearMax delivers a focused technical advantage and often a lower per-treatment cost when phosphate control is the primary objective.

AquaClear’s Ammonia Remover insert is a plug‑and‑play polymer sachet packed with ion‑exchange material that excels at rapid ammonia control and emergency use, providing quick peace of mind for new setups or acute spikes. It is generally more affordable and simpler to install than multi‑media sachets, but because it is focused on ammonia removal it is best used in tandem with broader‑spectrum media like API Zorb or Boyd Chemi‑Pure Elite for ongoing water quality management.

Seachem Purigen in a filter sock format is the premium polymer adsorption option focused on high-capacity, regenerable organic removal, making it the technical standout for hobbyists prioritizing clarity and long-term cost-of-ownership. Compared to granular or polymer carbon socks (Aquatop) and phosphate-focused socks (Two Little Fishies), Purigen delivers very low dissolved organics and can be chemically regenerated to extend service life. Its higher upfront cost is offset for many users by reduced replacement frequency and superior polishing performance.

Eheim Substrat Pro is a sintered glass bead substrate that offers a chemically inert, scratch-resistant medium with excellent conditions for stable biofilm growth. Against polymer foam media, Substrat Pro’s advantage is mechanical robustness and minimal long-term degradation — it won’t compress or shed fibers like some foams — making it attractive for aquarists focused on permanence and minimal media turnover. It is typically a higher-cost, premium option but can reduce recurring expenses because it rarely needs replacement and traps less fine detritus, preserving biological activity over the long term.
