Is this RODI setup correct?

Success! Thanks so much Russ.

I am filling the 180 now

BTW anyone know where to get a cheap TDS meter? Home Depot doesnt have them.

Got mine from BRS.

That's some real dedication btw... problem solving at 2am so you can start filling your tank. Respect!

Yeow. Someone sold you a less than ideal set of prefiltes. Assuming you are on city water w/o chloramies, a good combo is a 1 micron sediment filter and a 0.5 micron carbon block. GAC prefilters really have no place in the high capacity systems we use in this hobby. Really no need for a third prefilter, but you could use a second sediment filter or a second carbon block if you'd like.

They were included with the unit. So its not a good idea to use the ones included? So 1 micron sediment filter and two 0.5 micron carbon block?

BFS is definitely getting some business from me!

Yeah, pretty hard to beat service at midnight. This was a good teamwork thread, lol.

Carbon blocks do a much better job than GAC in this application - so much better that the GAC isn't really worth having in that position.

If you don't have chloramines in your water, you only really need one (1) good quality carbon block. You can lease the other (third prefilter) housing empty. I wouldn't use two 0.5 mic blocks because you'll lose a bit of pressure with each. If you DO have chloramines, go:

1. 1 mic sediment
2. Catalytic GAC (CGAC is much superior than plain old GAC)
3. 0.5 mic block

OR

1. 1 mic sediment
2. 0.5 mic block
3. 5 mic block

Awesome, thanks again. I know you recommended better alternatives but does it hurt for me to use the 3 I presently have? I dont want to spend if I dont HAVE to. Tight budget haha. Plus I already started filling the tank and it got me all excited.

If not mistaken, Buckeye Field Supply has them. Not going to find that much difference in price through various vendors, a dollar or two here or there. BFS was kind enough to walk you through getting it working, that probably has some karma.

Mike - you are a scholar and a gentleman!
