Ro/Di system question

[Yolofly]

Hello there,

I'm new to the ro/di water system and was wondering if you guys can help me. I have a 60 cube tank with a 10 g sump, a 75 g tank with an 30 g sump and a 29 g QT tank at the moment. I got a 55 drum in the house( taking space) and was thinking about buying a ro/di system and just filling that drum up every week for water changes. I saw different stage and was wondering what would be a better choice for me 4 stage or 5 stage. To help me decide, I did a API test for my city water and found

PH - 7.8
Ammonia -0 ppm
Nitrite - 0 ppm
Nitrate -5 to 10 ppm

I was really surprise about the results, but was thinking about buying a 3 stage, 50 Gallon by day system. DO you think is enough or do I need the 100 gallons a day? Do I need a system with more stages or 3 would be enough?

Thanks

Really just depends on how much you want to spend and how much water you use weekly I think either would be fine for you. And for how many stage unit you will need see you have city water I also have city water I use a 5 stage but a 4 stage should do the job as well.

What does the three stages include?

If you're wanting to determine the quality of your tap water, what you'll want to measure is the TDS(total dissolved solids) of your tap water and find out what makes up that TDS. But with most cases, a 4 stage will work well, Bulk Reef Supply sells some great systems.

Given the amount of tanks and water volume you have you'll likely want something that has a higher production rate that 50 gpd. I have one made by SpectraPure that I believe does 90 gpd. However, your production rate is going to be dependent on your water pressure as well. If your water pressure is low then you won't get the amount of production the unit is rated for and might have to add a booster pump.

Regarding the number of stages, as @AcroNem mentioned that is more dependent on your City water's TDS. I would also recommend finding out if your City uses chlorine or chloramine to disinfect their water. If they use chloramine, you'll likely need a five stage system to make sure it gets completely removed from your water.

Thanks for the reply guys,

I did check the process and found that they only use chlorine. @AcroNem @muzikalmatt
I check the Coralife and Aquatic Life and my lfs have other brands. @KStatefan
