Hi all. I've been having a minor algae problem so I purchased some EasyCarbo to nip it in the bud. I added it for the first time this morning (half dose: added 0.6mL given that my tank holds 60L water) but since then my Amanos have been acting weird. Initially they were swimming around like mad like they do after a WC. Then, two of them (out of 3) went completely still. One has now moved but the other is still immobile. Can anyone please confirm that EasyCarbo is safe for shrimp? I am a bit worried about them. I don't plan to use this long term, I'm only using it to tackle algae.
