Snails behaving oddly after water changes

[JamieLu]

I have a 10 gal specifically for ramshorns. We just moved to a different county and our water here isn't great since it has high nitrates. Anyway, every time I do a water change for the snails, they fall over on their sides and stay that way for roughly a week to 2 weeks. They will retract back into their shells if touched, but they can't move around. Some hang outside of their shells, others inside. I just don't why this would be? So if anyone has any info about the cause or anything I'd appreciate it. Thanks

What is the Nitrate level in your tap water? Also check it for ammonia. pH.

Nitrates are about 20-30 out the tap. ph 7.8 ish tho I'd say it's closer to 8.2 in the tank so slightly raises over time. Also no ammonia in the tap, tho I have never seen ammonia do that to snails before anyway, even in a cycling tank. Not saying it doesn't happen just never has with mine. Could it b from excess heavy metals or something? I dunno, it clearly messes with them

How often do you do your WC’s and what percent… may want to look into something like Nitrazorb I’ve heard people on here use it with good results.. are their shells ok do u have live plants? Do you have a pic of the tank.

I do about 60% weekly, 5 gal. I only have moss right now. Ive slowly been taking everything since I have a pretty bad planaria issue. Some of the snails shells r good, some not. I supply them with cuttlebone, have done eggshell but that made planaria worse, and feed them veggies regularly. My 2 other tanks have no she'll issues, only this one. And I haven't notice water changes affecting the snails in other tanks, tho they are bigger tanks and less snails. I'll post a pic but please excuse the mess, they had carrot and cauliflower the last 2 days and I haven't done cleaning yet I may look into nitrazorb for all my tanks as well

How is the surface agitation in this tank ?

It not great. I have the whisper filter I believe, possibly on low? I'll have to check when I get home but I do tend to get excess film and foam on top.
