Marine Depot The key component for any reverse osmosis unit is its membrane. The membrane will determine the type of contaminants removed and how much water the unit will produce. Our Marine Depot Hi-S (High Silicate) membranes are the gold standard and will remove 96% of nitrates and up to up to 99.5% of silicate. Chlorine will ruin TFC, Hi-F, and Hi-S membranes so prior carbon filtration is required. All Marine Depot Membranes and RO and RO/DI units are designed and manufactured in the USA.

Please note that these Hi-S replacement membranes are interchangeable with Kent Marine, and SpectraPure RO or RO/DI unit. We have researched and tested the best replacement membranes among all manufacturers, and offer only the best available.

Manufacturer Info

Marine Depot was started in 1998 by a self-professed reef geek and pre-med student Ken Wong. Ken envisioned a one-stop shop where customers could find everything they needed, from technical product specifications, reef aquarium information, expert advice on the hobby and friendly one-on-one customer support. Having grown from a one-man crew to being one of the world’s largest suppliers of reef and marine aquarium products, this very core philosophy still lives strong in the Marine Depot culture 19 years later.

REVIEW
I have no way of measuring the TDS on these, but I replace them every year or so depending on my usage and keep a variety of coral and fish with bright LED lights and very little algae growth and no detectable phosphates. This membrane appears to be working as it should.
