Can i use DI Only water for shrimps?

I happen to have a spare DI only unit not those with RO.

Can i use it for shrimps? i recently did a test on the DI water with zero tds, kh zero and a Gh of 4 ( i understand that DI water should have a GH level of close to zero).

How do i bump up the KH? i tried other products to re-mineralize but it often bumps the both the GH and KH. If i use that product to bump the KH to 4 , my GH will be quite out of range.

Any work arounds on this?

Its not possible to have a GH of 4 and your tds shows 0. Its impossible. Its your gH test maybe gone bad. With a Gh of 4 your tds should be 90+

Definitely something gone awry here. GH is a test of, basically, dissolved Ca and Mg in your water. A GH of 4 would completely prevent your TDS (total dissolved solids) to be 0.

Just curious if you use DI water and it comes out to 20 ppm do you still need to use declor/prime?

If you have GH still getting through, then you might have other things getting through as well.

TDS pen might need to be calibrated.




If you want to be safe, you can buy GH and KH products separately, then use as needed for your tanks. Having said that, some people do use baking soda to raise KH in their tanks. I can't necessarily say it's a good idea but it is a somewhat common practice for people who don't want to pay for a KH product.

I think you Gh test is bad and not tds pen. Check the tds of tap water and then check DI water. If your tds is zero then your KH and GH is also zero too.

That DI canister is going to last you a whole of two seconds if you are not feeding it near zero TDS water so honestly I wouldn't even bother.
