RODI Filter Recommendations for Shrimp?

Hey, guys!


I'm in the market for a decent RODI unit for my bee shrimp. I'm getting sick of having to pick up gallons of water every time I go to the store and I think the filter will pay for itself in the long run. That said, I was hoping to get input from those of you that have them/have used them and what you recommend.


I was looking at this unit here: https://www.bulkreefsupply.com/4-sta...ef-supply.html


That BRS unit is a little more money than I really want to spend but am happy to pay for quality, if it's worth it.



I look forward to reading all the comment and suggestions!


Thank you in advance.

mine is cheapest 4 + 1 stage 50g for drinking water, I found it from evilbay, includes a 4 gallon ro storage tank.
Look exactly the same as the one from reefbulk, but without the tds meter and the pressure gauge.

I believe it is the filter that is important, most of the ro system brands you can find are re-branded, only one or two manufacturers mass producing the low tech parts of the system, but the heart- the membrane filter is from GE.

You get what you pay for, and that's not too bad of an value. Good site to get one from too.

Just remember you can use the RODI unit for other stuff too. My home has sky high nitrates that wouldnt be safe for baby formula.

One you have it setup you'll need a cutoff value on the beginning or you'll need a storage tank with it's own cutoff system.

Here is another good unit

https://spectrapure.com/products/aqu...aqua-st-kit-ii

They also have great DI resin. You can get ones that make sure there’s is no
Silica which diatoms use to grow.

I've had the SpectraPure Max Cap with the silica buster DI for over 10 years and have been very happy with it. It's a great unit though is overkill for my current water production needs. While I agree that you get what you pay for to a degree, the biggest difference you get for paying more will be the gallons per day and ratio of wastewater produced.

Nothing good happens fast in an ecosystem.

Ooh, I like that unit. Seems to have everything included that you would want. I may end up pulling the trigger on this one tonight!

Like a lot of water production. Don’t like waiting all day to fill up a container of water. As it leads to water all over the floor.

I was worried that I'd be buying something I totally didn't need. As someone else said, though, it can be used for other things outside of the tanks.


Now, I just have to hide this purchase from my wife!

No RO unit is exactly "fast," but taking all day to fill up a water tank is for the birds.
