So my little office tank...

Tds unknown
Hardness around 100
Ph 7.2
Alkalinity around 120

My crystals white has been transparent for like over a month had one that was even berried, normally ph is lower but did water change today, any ideas on the loss of white?

Would be ideal if you could measure TDS, KH, GH.

What's the water temperature?

Diet?

pH is obviously on the high side.
I don't have any equipment to test tds, or gh/kh currently

Water temp remains around 74, building is constant temp

Food is a variety, color, frenzy, barley, grow, spinach etc. I mix it up feeding to feeding.

its probably your tds. from what i hear/ read they show more whitness with more minerals
Guess i need to invest in a tds meter, so possibly implies tds to low?

Trying to attach some photos... Currently suffering some difficulty

pH is ok but could be lower. though low grade crystals not only show less quality white, they will also live better in this pH than high grades with more white could. it can be becasue of the genes. did your shrimp start out very white?

you'll want to put in a small piece of cuttlefish bone, make sure your TDS is within specs. if using DI or RO water make sure you are remineralizing with a shrimp GH product. there a lot of good things for shrimp to build healthy shells in those remineralizers.

KH should be near 0dKH.

Are you using tap water?
your diet sounds good.

Using tap, thing is had these shrimp at my house on tap and their white never faded.

They seem healthy, they Berry, eat very active etc

Only difference is at home used sand, this tank has blasting grit (black diamond).... Could be a mineral thing hrm.

Cuttlebone like what birds use?


Ph normally is around 6.8 just did a fresh water change today though

you said that pH was 7.2...now its 6.8? make sure its not fluctuating daily. that causes stress and color fade.

yes that cuttlebone. cut off a small piece.
substrate doesnt matter since its now even darker than before. their white should be more intense...

must be mineral or stress related. (IF they were solid white before)
otherwise its their genes and they will stay this way with maybe mild improvement.

Appears to be mineral related, picked up some "white" shrimp food ( supposed to boost the white color) just in the last week or so have seen an improvement in the white color, just picked up some cuttle bone hopefully just improves from here on out

I find that whenever i use GH boosters and distilled water, I get much better white on my CRS.

Also the cuttlebone might float for a week, but it will eventually sink. be patient with it.

So resurrecting this thread a little.

Found out my gh was to high! Some rocks I had added were increasing it. V removed them...

Maybe 2 weeks later berried crystals. Go figure :-/

Also testing the tap here shows that gh in the water from the tap has also increased some... Time to get some distilled
