about the DI resin expirary:

I have a RODI unit that i ordered like 3 years ago and have not used it before

recently want to get back into the shrimp hobby and dig back out this unit to use, but found it the DI resin changed to brown color already

 

is it okie to still use it even the color change and I have not use it once?

the TDS came out after is around 1

 

about the size of replacement filters:

currently, the site that i bought the RODI unit, the replacement filter's size is 9 7/8"

but I saw some other ones online with 10", will this fit with the 9 7/8" since its only fraction of the size?

 

Also, what do you do with the water inside the RODI unit if not use too frequently (only has a 10g tank)? Do you guys just leave it or you guys drain it out even the 3 filters?

If the TDS is still ~1, then it should be ok.

 

If the RO water in the storage tank is old, throw it out.

      Good video by Chris Lukhaup!

      One interesting thing he mentioned was "Bacteria pressure", which I guess just means number of bacteria around.  Yet I see all these other videos from shrimpkeepers bragging about how much bacteria their filtering system holds. Also interesting is no mention of using anti-biotics to treat bacterial infection.  I think that has fallen out of favor recently.

      Finally set up the 30L Shrimp Tank

      By sdlTBfanUK · Posted

      It has been a few weeks now and I have done a couple of large water changes. I tested the water parameters this morning, GH6 and KH2, TDS 140 and PH 7.5. Obviously the PH is off but there isn't anything in the tank that should cause the PH to rise to this figure so I will just run the tank for another month with 10% weekly water changes (probably just with RO water) and see where we are at that point. The RO water tests at PH6, and the KH and GH in the tank could come down as they are at the upper limits for Caridina shrimps! There are only about 10 very small snails in there at this point, but they seem to be doing well enough.

      Pure Red Line (PRL) Shrimps Western Australia seller

      By sdlTBfanUK · Posted

      I believe these to be very rare in Australia so you may even consider making it a longer term plan and produce your own by starting with the best CRS you can get as that is where the pure lines started! Depends how patient and interested in the project you are, but would save money as well? If I recall correctly it takes from 8 generations of selective breeding? They sell them at micro aquatic shop but do not ship to Western Australia, but that means they are available in Australia. https://microaquaticshop.com.au/products/pure-red-line-grade-ss-shrimp Good luck and just maybe smeone on here may point you in the right direction or be able to supply you with some.
