rodi water

Is it possible if I can make rodi water and not use an rodi system to possibly cut costs?

Having Reef Tank water chemistry issues or Algae blooms? Better your tank with the use of RO/DI water. Available for supply is 0 TDS RO/DI water. Consistency is key when it comes to water parameters. Using high quality H20 is a great start. This water is produced using a 7 stage water filtration...

So I was gonna buy a 10" standard RODI Unit but it's like $300 brand new (CAD), but I seen on my local classifieds that someone has a 4 stage (or I think it's actually a 5 stage) for under $100 (CAD) but unsure of the brand (seems like it has no name), but the person said it's practically new...

I only just got a TDS meter after making about 150-200 Gallons of RO Water with the “Aquatic Life RO Buddie Three Stage Reverse Osmosis, 100-Gallon”. My tap water is reading 70ppm on the TDS and my RO is reading 4ppm. I know 0 is ideal, but does 4 mean I’ve burnt through the filters already...

Hi all. I am trying to prepare a freshwater dip for my seahorses and can't find a "recipe" for how to raise the pH in the rodi water, using bicarbonate soda. Could you please tell me how to do this? How long after you have added and mixed the bicarb to the water should the levels test...

My Question is it ok to top off with RODI Water during Cycling since I’ve noticed some evaporation? I just want to make sure so I don’t ruin or mess the progress of the cycle with my Ammonia dropping to 0.25 and the cycling is coming along the Nitrites up to 5.0 and Nitrates starting to build...
