BRS RO/DI system

[ChrisWhit483]

I am still very new to the saltwater world. I have a 32 gal nanocube, but just found an amazing deal on a 215 gal tank. I will be going very slowly with this tank and my first question is about filling it. I do not live close to LFS. I already have the BRS RO/DI 6 stage deluxe plus 150gpd system. I have not even taken it out of the box yet because I have had plenty of water from when I initially bought the 32 gal tank. I am wondering how many gallons I can make without having to replace the filters, membranes, etc. Is it feasible to think I can take a few days and make enough of my own water at home to fill this tank? Help please, because I also do not want to have to drive 2.5 hours to buy 200 gallons of saltwater either.

Lifespan will really depend on the quality of your source water, but you can certainly make 200 gallons.

This should be in the region of 1000+, unless you have really really hard water or loads of TDS.

The cartridge refills are almost certainly going to be a fraction of the cost of LFS water.

IMO above a 50 gallon tank a RODI system is an absolute no brainer provided you have somewhere to put it. The break-even on setup costs, especially if you have it to fill the tank, is in “weeks”.

Our water is honestly terrible, very hard and full of chlorine. As mentioned I live 2.5 hours away from LFS so it was a no brainer for me to buy my own system instead of having to drive 5 hours round trip for water. So basically I should be able to make around 1000 gallons before needing to replace filters and membranes. I was mainly wondering if I should go ahead and have new filters, etc on standby before I even started making water or not.

Thank you

I have a 340g system and I replace filters every 6 months if I am doing 20% water changes every week, but only yearly if I do 3g a day water changes.

I filled up my new tank using BRS 5 stage water saver RODI and burned through the DI resin in 200 gallons.

Guess my water is pretty terrible.

 

[Chrisv.]

Do you have a TDS meter hooked up to the system? This is a good way to measure when your di resin is spent.

I do not but will get one.

Yikes! Ours is pretty bad so I'm hoping that doesn't happen to me.

They are relatively cheap. I suggest getting the in line version they sell at bulk reef. It's also on saltwater aquarium and Amazon. Hm digital is the brand, I believe. I am a fan of the three probe version that allows you to measure input TDS, post-ro TDS, and post di (product water) TDS. Good for keeping an eye on when the ro membrane gets inefficient too.

Well I just looked and it says the system I got comes with HM Digital Inline Dual TDS Meter. So I guess it comes with it. I have not even opened the box yet.

Oh nice! Perfect. It's pre installed.
