Higher kH stabilizes pH which can drop due to excess organics. Fluctuations in pH aren’t great for shrimp. Large water changes can also mess with shrimp (temperature needs to be exact and other parameters similar so no large fluctuations) so I recommend if you are doing larger water changes...
I’ve done a few small water changes and have been dosing with ParaGuard daily since some tiny white Planaria showed up... no deaths since! But I’m not sure how long to dose the ParaGuard. Seems to be shrimp safe and as a bonus I’m also using in my hospital tank to treat a shrimp with...
I had a heavily planted tank and the ph of the tap water was 8.2 yet in the tank it was 6. Kh was 1. Tank wouldn’t cycle (it had been 4 months) until I added aragonite to the tank. Then it finally cycled within 2 weeks. It needed the kh up to stabilize the ph.
They appear healthy to me but a picture is worth a thousand words... I think it may have had something to do with a water change that was a little too big before with water that was a bit cooler than the tank- what do you think? Plausible?
