D-D Replacement Cartridges for RO Units

A lot of people use Reverse Osmosis Kits these days and for good reasons too. Our tap water is full of chemicals and minerals that a lot of fish cannot tolerate. In particular marine aquariums where salt is added directly to RO water. So you can probably imagine a lot of people rely on the RO unit a great deal.

We would like to introduce to you the D-D Replacement Cartridges specifically for the D-D RO Units.  The cartridges are often overlooked by hobbyists but like everything, RO units need maintaining. There are 2 different cartridges available:

10″ Carbon Cartridge – replace every 6 months

10″ Sediment Cartridge – replace every 6 months

Both are cost effective costing £6.95 and £2.99 respectively and help keep your water to remain pure and clean.

Minerals for water of reverse osmosis and for soft tap water

In a marine aquarium reverse osmosis water is used for topping up evaporated water. The only snag with RO water is that it removes everything from the water including valuable minerals.

With Tropic Marin Re-Mineral Marine the water of reverse osmosis gets back all its beneficial natural minerals and substances and at the same time the alkalinity is raised and stabilized.

Many remineralisers only add certain minerals back into the water (such as calcium) where as Tropic Marin Re-Mineral Marine adds everything that nature would expect in the sea in terms of trace elements.
