AZIL'S RSR 250 Reef

Definitely give your barrels and containers a good wash wish soap. But make sure to rinse it off properly as well, make sure no soap residue

If thorough cleaning still doesn’t work, perhaps the barrel/container is leaching out something and you should consider changing them.

Also, are your barrels and containers closed with a lid?

[R0B]

Agreed. If your RODI is producing 0 TDS then either you meter is reading an error (test it on some distilled water or RODI), or as@marcel says your barrel is contaminated.

Interesting as Singapore has very good quality water. Mine reads 68 out of the tap. So to get a reading of 200+ would mean something was added.

Has any of the containers been cleaned lately? are they covered or open to air borne pollutants? Have they had salt in them? If used for salt mixing then some salt residue could be skewing your results.

I suggest you wash them out with the zero TDS water and throughly dry them. Add some clean rodi to the barrel and retest every hours or so, if the TDS starts to go up then your barrel is leaching something.

Hope this helps.

Thanks for the advice guys. I ordered a new barrel. Have checked with the seller. They washed the barrel with some kind of soap. Have washed the barrel twice but still the soap fragrance linger in the barrel. 200l of water wasted and salt 

 

Have emptied out the tank. Will let it dry and I'll fill it back again

Anyone know for a 5bstage rodi, supposedly it should be 0tds right. Occasionally I'll get 1 or 2. Kanyone know why? 

[R0B]

If the machine used to produce 0 TDS and is now producing 1-3 TDS this is a sign of needing to replace your resin and/or filters. If you never had zero TDS it may mean your system is not optimal. In reality a five stage system should be getting 0 tds.

All in all 2 TDS isn't something to keep you up at night in the short term but it could become an issue in long term depending on what that '2' is.. for example if it is a heavy metal, then over time this could cause algea or other more dire issues the longer you leave this unresolved. So you shouldn't worry too much, but dont ignore it either.

I found adding more stages doesn't typcially rectify the situation (I have 7 stage system) so dont spend the money here. (That is more about specialist needs). What does matter is the quality of components. So focus on getting the best filters. Note I find the carbon filters commonly available in local LFS's to be designed for drinking water (coconut carbon) and not completely optimal. (LFS's please carry GE filters)

But there are other factors. here are just a few.... water pressure not enough for RO membrane, water volume not regulated correctly. Bad quality filters. Filters are simply old and need replacing. Not flushing filters long enough, Filter body not cleaned correctly, filters not installed correctly, DI resin got damp in storage (reason never to buy second hand DI resin), DI resin not packed sufficently/correctly, water channels in DI resin. TDS probe quality.

Many factors. Maybe one or two of these ring true for you.

Hope it helps.

Thanks Rob for taking time to address my concerns. The tdo monitor on the unit self states as 0. But when I used the handheld one sometimes it read 2tds.

Maybe I shall monitor the water pressure when doing the next batch of rodi. I plugged and play after receiving the unit. I did flush them twice. Before storing the water. 

I connected the water source via my bidet area in my toilet. After I'm done using it I dismantled the unit from the bidet and store the unit self in my store. I assume theres still water in the system which will not affect the tds when I'm using the next round right?

Just curious how come ur RSR tank background is not black, I thought usually the Nano/170/250/350 series back of the tank are all blacked out
