There's is Mosura Brand R.O unit which is design and build for shrimp available in market. You can check it out with Green Chapter or drop by to take a look at their display.

Or you can try getting portable units from Amazon. The mighty mite RO unit seems quite popular.





So far the mosura brand is the lowest in Singapore which I can find.
The portable RO unit from amazon are good but thinking of getting the replacement would be a headache. Hahaha
Replacement of all the filters are always a concern. I would much rather find a reliable local vendor who can supply these in the long run.



sorry to hijack your thread,
i have those water cooler unit at home, for drinking one. i realised that the tds reading is the same as distilled water, so is it consider RO water? do i need to add anti chloride or age water water? or use it for water top up?





Loudness, you might want to check the specification of the water cooler you have. If it has activated carbon cartridge in your cooler, I believe it should be chlorine free.
I did enquire if the RO water(using this ro system) could be used for human consumption but the answer returned was that they wasn't sure and it is sort of a deterrent for me to buy it( not really worthwhile to get,if it is only for shrimps) .. so does anybody know if this water is possible for human consumption?
Aspiring to be.



my water cooler has activated carbon cartridge in it, but i still dose anti chlorine, is it ok?
bro leefhker,
maybe you can try find for human consumption one, like diamond brand, check if it's safe for shrimps.





Loudness - it is still ok if you dose anti chlorine like prime, let it age for a day. I think i read before from seachem that if we overdosage of prime into the water, let the water age for at least 1 day to allow the effect of prime to wear off.
RO should be safe to drink just that the water lose out all the minerals which are supposed to be good for our body.
Also take note about your RO unit like diamond water, there is one time I happen to see the internal system of the diamond water unit installed at my in-law place. The piping they used in the unit are all copper piping which is not suitable for shrimps.



Diamond water is mostly fancy marketing to me but I can see how its meant to cater to human drinking preferences (better tasting, aura energy enhancement, nano tech jargons etc).
However, it may not be good for some shrimps.
For one, it produces alkaline water, not neutral or acidic.
Secondly, the water produced has anti-oxidant effects, meaning it'll lower the redox potential of the aquarium. Since redox is still not a well understood parameter for freshwater aquarium, I cannot say if its good or bad, but too low a redox is definitely bad.
Thirdly, it remineralizes the water by running it through some mineral rocks filter cartridge. What minerals and how much TDS/GH/KH it adds to the water I don't know but for sure it'll add KH because there's mention of calcium ions.
Only good thing is that the water coming out will definitely have no toxins or chlorine as there's activated carbon in 3 out of 6 of the filter stages. Overkill in my opinion...
I doubt they would use copper pipings for the filter unit as it corrodes easily and will choke the filter. Most likely those are brass pipes

Does the diamond water machine produce any waste water? I know the waste water from those alkaline water machines is actually acidic. Anybody has one of those machines and have tried using the waste water for shrimp tanks?
guess it will still be better to rely on distilled water if needed...
Aspiring to be.
I do not think so?
If you refer to this
http://www.diamondwaterweb.com/produ...s.html#compare
and scroll to the part where the 6 stages of filters are described, can you see any form of technology that will result in waste reject?
The only "advance" looking tech is this KDF filter, which is basically an ion exchange filter that works based on ORP differentials to remove heavy metal and chlorine.
