Hi wonder anyone have any inforamation on how water change that will not kill the CRS shrimplets?

Recently saw some CRS & BDS shrimplets in my tank. However after I made one 20% water change, all shrimplets disppear. I am very careful during water change that I do not suck them out and water was treated before added in. But where are all the shrimplet go??? Died???

Sure die la. Chloramine so high, even tetra will die. Shrimplets so small have no defensive system. Rem not to change water to shrimplets tank. Only add old anti chlorine.

Hi does that means that only top up water treated with anti-chroline? Those water I added during water change was also treated with anti-chroline.

Definitely have to use de-chlorinated water even for top up

Best is, don't change water.

I try not to change water for my crs tank. When i change water, i realize my shrimplets will die.

When i top up water, i top up from my sakura tank to my crs tank.

CRS don't produce so much nitrate. so not worried my nitrate level is high.
