Filling RODI Resin.

[Reef.]

I agree with this. Takes my sediment almost a year to get any color to it. It is 34 tds spring water from a well. My membrane is 3 years old and still has a 99% rejection rate. (Measures 0 after membrane, but highly doubt it is exactly 0).

remember tho that TDS is not the only measure, some things you wouldn't want in your water won't measure TDS such as ammonia, silicates in excess to cause diotoms and chlorine/chloramines

I change the sediment and carbon block yearly. The membranes (I have 2) every other year and the DI when it reads one.

Correct, but is a good starting point to reference.

You have me worried now as I filled right to the top and still managed to get the lid on

May want to reconsider doing this. I've had a couple burst inside of the canister doing this.

Mine has only a sponge under the lid, I did notice someone say theirs was a rubber seal under the lid? There wasn't much resistance so think I should be ok?

I've just upgraded my carbon from a standard to a chlorine specific one, says it's good for 50,000 gallons, I only have a nano, was going to try for 12 months?
Are these filters only exhausted by water volume or time too?

I do agree changing more often is a good move but don't want to just throw a perfectly good filter away, I'm also moving to 3 mixed bed resin canisters system, will change one resin every 3 months, as I have just experienced quite bad diotoms because I waited too long to change the filters.

You can do what the manufacture says which is 3-9 months per filter and 1-2 years per membrane, however, I have had filters go bad and cause issues so I quote 6 months and 12 for membrane. Since then I have never had an issue again. All filters once wet have a countdown clock. Now if one was running 24/7 and there was never air hitting these guys that is one thing, but in our industry we turn them on when we need to make water then when they are not running air gets into filters and membrane.

A beer bottle fits just right!

Good point, I was thinking using it less was a plus, probably more a minus looking at it like that.

Think I'll do that.

Any tips on filling the resin cartridge?

Just filled mine, not looking forward to doing it again, a lot of banging and I'm still left with the feeling I haven't compacted it enough.

That was me not so long ago, I over thought everything and had my wife looking at me like I was crazy banging the container on the family room table lol
I went by thirds tapping every couple of minutes until I couldn't compact it any more and still I thought it might be wrong or incomplete but it worked just fine. Yours will too!!!
