Low GH (or high GH) can cause moulting problems, which would happen 1 shrimp at a time.
I am leaning towards the change to distilled as the cause. You have a 5 gallon tank. Your water change is 20% (1 gallon) every two weeks.
Changes in water parameters, like that first time you used pure distilled, will frequently trigger breeding (survival instinct... water changing, we might all die off, better breed quick).
Sustained water variability will crash the colony.
Every time you take water out manually, you take minerals out with it. If you don't add them back in, you will eventually drive your GH all the way to 0.
If you are topping off evaporation, then use your pure distilled. Because evaporation leaves the minerals behind, you are restoring the balance.
On water change day, you might want to consider tap water, or remineralize your distilled with one of the fine remineralizers on the market.
Shrimp love consistency.
Slowly raise your GH back to about 5 or 6 and you should recover.
My opinion above is based on reading the internet and running a colony for about 2 years. I crashed a colony of RCS by switching to RO water and not remineralizing. I hope this helps you.

Yes control the air around the tanks and you won't need heaters in the tanks or chiller or fans.

Happy Thanksgiving everyone!

Some more pictures.

Pretty interesting video. First the narrator talks about Hydra, then Planaria, and also Molting issues for lobsters.. I've pretty much encounter all three issues in my shrimp tanks.
 

I switched over to using Amazon S3 this morning.  The photo links will likely be broken for a while as the data migrates over to Amazons servers.
 
I think I have seen other posts about people using CloudFront with IPBoard so if the photos are loading slowly I will look into it more, the IPBoard support said that we shouldn't notice a speed difference.

Some pictures and videos. Updating more tomorrow.

The forum is hosted by invisionpower (company that develops the ipboard forum software)  who also takes care of updates and problems that arise.  Additionally it covers the cost of the forum software which you have to purchase if you host on your own server. 

Going to start building up more tanks.

Hi everybody,
 
Though it is time for a update, some CRS pictures
 
My S colony 
 

 
My SS colony, im working on the Hino/No entry here 
 


 
and my SSS
 

Patiently waiting to see her babies.... 

Can anyone tell me if she's berried? [end sarcasm]

I wonder if Han takes the clean sticks back for credit? They look brand new after the shrimp finish with them. [emoji851]

It's a shrimpy pop from Han!

glad you enjoyed the video! [emoji5]

@Mr.F what is that interesting dirty stick that your shrimp cleaned for you? It almost looks like you took a bamboo shish-kabob skewer and left it in a bucket outside for a few months to grow stuff on it as a shrimp treat...
The video was so entertaining that I watched it 4 times.

I myself add small fertilizer and remineralize in a 5 gallon bottle. Then I do a 10% water change from that container once a week for a month. The incoming and outgoing water are close enough that my shrimp don't seem to mind. My TDS go down about 10 points during the change and my GH does not budge. I could drip it in, but in practice it does not seem to make a difference for me.
I have seen other members like@bostoneric talk about just adding raw RO directly to the tank and adjust with SLAqua Blue Wizard right in the tank, using TDS pen to know when to stop adding.

I have been watching an absolute religious war on the benefits of water changes over on TPT for the last 2 weeks or so. The thread is just full of all the worst kinds of internet zealots.
 
It made me realize how civilized, open and generally supportive the community here at Shrimp Spot is. And I am grateful for it.

My favorite Red Bolt is berried, woo hoo!
