CRS white turning dull

Hey guys I'm new here! I have some SSS CRS and their white colors have turned a bit dull over the past month that I've had them. It's similar to a yellowing white color, but their tails maintained the crystal white color. They're 1/2 to 1 inch long some still not mature enough to determine whether they're male or female. They were crystal white when I received them in the mail.
I've done a water test and here are my results:
ph: 6.6
gh:8
kh:1
tds:160
temp:73.4f/23c

and food I feed them is Shrimp king complete, SK 5 leaf mix, SK protein, SK mineral and SK snow pops.

Do you think the gh is the culprit or genetics? Any feedback would be appreciated thanks!

Could be genetics, diet or water parameters. It's typically recommended to keep them in GH of 3-6.


Are you aware of what the "parent colony" CRS appear like? Or what water parameters they were being raised in?

I see.. well Iíve done some water changes with R/O water in this month about 3 times and I know itís slowly brought down the GH but it also lowers the tds so I usually added equilibrium. Unfortunately that raised the gh as well but Iím looking into getting another product to not affect gh too much so Iím exploring what other successful shrimp keepers use.

The parent colony are actually pristine white so Iím not too sure itís the genetics. Would you happen to know any way to bring the gh?

Thanks!

Older CRS colors would dull as they age but this might not be the case if they are only 1/2" as you said.

I would recommend using a shrimp specific remineralizer such as Salty shrimp GH+ and adjust the gh accordingly. You can lower the gh by either diluting your tank with RO gradually or through water changes.

The shrimp in your photo appears to be a female based on body shape and possible saddle development.

Equilibrium contains a significant amount of Potassium and also contains some micronutrients. Raising TDS is unnecessary - it's a benchmark that is only useful when compared to its previous values in your tank.

On the other hand, Equilibrium does have a good calcium to magnesium ratio, so using it to get your GH to around 4-6 is fine.
