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.
