The importance of using Reverse Osmosis (RO) water for use in an aquarium cannot be over emphasised and so D-D have a full range of high quality Reverse Osmosis Units for all applications.

Reverse osmosis water is essentially free from chlorine, nitrates, phosphates and heavy metals and is an ideal base for making up salt solutions or for freshwater aquariums or replacement of evaporated loss.

Tap water is generally full of these pollutants and the effect on your aquarium can be quite severe depending on how bad the water is in your particular area, fueling algae and diatom blooms which must be then maintained by chemical methods.

All D-D RO Units come complete with the following:

  • Flow restrictor with integral membrane flushing valve.

  • Self-piercing tap connector.

  • Threaded tap connector.

  • 2m of 1/4" RO tubing in white, blue and orange.

  • Saddle valve for the waste pipe return.

  • Filter Spanner.

  • Full instructions.

Dimensions (HxDxW): 39cm x 13cm x 35cm

The 3 stages consist of: 

  • A 10" 5 micron pre-filter to remove sediments and particles from the mains water

  • A 10" 10 micron block carbon filter. This carbon filter is designed to remove the chlorine from the water.

  • The RO Membrane and housing. This stage holds the membrane itself. All D-D membranes are high quality thin film membranes.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
