Is there a big difference in the water quality between ro and ro/di? Looking into purchasing a unit but also trying to keep costs realistic. Thanks.

Absolutely Depended on your source water most RO membranes have a 99% rejection rate, which means some TDS is going to make its way through. DI is that nice little polish at the end that brings you down to 0 TDS which means there are absolutely no dissoved solids in your water.Is there a big difference in the water quality between ro and ro/di?

So basically, if I'm battling high phosphates, which I am, I need the di because just ro doesn't remove them? Thank you for this. Now I know why I need the di in easy to understand reasoning.What @crabs_mcjones said.
Elements like copper, phosphates, ammonia (as ammonium) and silicates all are handled by the DI resin. These are all elements that are particularly problematic for reef tanks, and the only real way to get rid of them is with deionizing resin. Even if the final product water TDS after the membrane is very low, it could be very high in elements that are very dangerous for reef tanks.
I'm a self-proclaimed cheapskate. I'll never have an issue with reefers looking to save money. However, water quality is not the place to do it. This hobby is more about keeping clean water than it is keeping corals or fish.
What does the gpd mean? Lower gpd, takes more time to produce water?So basically, if I'm battling high phosphates, which I am, I need the di because just ro doesn't remove them? Thank you for this. Now I know why I need the di in easy to understand reasoning.
GPD stands for Gallons Per Day. It's how much water you're able to produce with your RO system in a 24 hour time period.What does the gpd mean? Lower gpd, takes more time to produce water?
Thank you. So if I do a 20g water change, ro/di unit with 50gpd should be fine? Can water be made a couple days ahead like I do now?GPD stands for Gallons Per Day. It's how much water you're able to produce with your RO system in a 24 hour time period.

Yup! So on average your RO unit should be producing about 2 gallons of product water per hour. And you can store it in your container until you need itThank you. So if I do a 20g water change, ro/di unit with 50gpd should be fine? Can water be made a couple days ahead like I do now?
Same here @XNavyDiver I was using a single stage DI canister, and recently upgraded it to dual stage. I got the 150GPD upgrade kit from BRS and it was recommended to double up on my DIJust chiming in, I agree with the others who say RODI. As a matter of fact, I just expanded my DI by installing a brs 3 canister expansion retro fit to my current RODI system. As it's been said before; we're water farmers.
Mine was a duel stage DI (with the two small tubes mounted on top of the whole unit), but I wasn't satisfied with amount of DI resin it was able to hold, so I went ahead and got that big 3 stage and bypassed the old two stage that came with the unit. Filled the first with cation, second with anion and the last with mixed bed.Same here @XNavyDiver I was using a single stage DI canister, and recently upgraded it to dual stage.

Nice! I eventually want to do the same setup. But don't have anymore room under my kitchen sink ;Hilarious Right now its just two mixed bed canistersMine was a duel stage DI (with the two small tubes mounted on top of the whole unit), but I wasn't satisfied with amount of DI resin it was able to hold, so I went ahead and got that big 3 stage and bypassed the old two stage that came with the unit.

I don't think there is an under sink cabinet large enough to contain my system. Six large canisters all lined up mounted to a wall in my garage! I looks ridiculous.Nice!

Alot of reefers have had good luck with that unit. The only thing to make sure is that you mount it vertically and not horizontally. What happens if you mount it horizontally is the water can channel in the DI chamber as the resin starts to deplete, and therefore doesn't get forced through the rest resin, and you'll start to get TDS creeping through while most of the resin is still good. If you force it to raise up through the resin from bottom to top, it doesn't get the opportunity to channel and pass through.Since I am in Canada, availability and cost become a bit of a factor. I was looking at this on amazon. https://www.amazon.ca/Aquatic-Chang...0095331&sr=8-1&keywords=aquaticlife+ro+buddie Would this be good to use or am I at the lowest level of filtering with this.
