Just be aware, nerite snails don't tend to last long in co2 injected tanks. I've had a few make it beyond 4-5 months. But anything beyond that is lucky. They do a great job on algae while they last though.

Good to know. What would be your recommendation for other breeds?
Very few snails can tolerate pH below about 7.4 for more than a brief period during the day.
Calcium carbonate dissolves away below pH 7.4, and that's what their shells are made of. Basically they are straight up chalk
All Marine snails are like this, as
are Mystery snails, Rabbit snails etc .
Ramshorn snails have a disproportionate amount of chitin protein matrix in their shells, which protects the calcium carbonate to a certain extent. So they are able to tolerate lower pH before their shells start to dissolve , maybe as low as 6.8 or 7. They come in a number of cool are.. And also multiply like tiny tiny bunnies
You can increase your KH by adding potassium carbonate or something, so that your lowest pH stays above 7.4 at the max CO2 you want to use, then nerite snails will be fine

Well, bladder snails are like aquarium cockroaches, they seem to live through everything. It doesn't take much overfeeding or algae for them to explode in population which is why most people see them as pests (me included). They're not super proficient in clearing algae because they're so small but they will help manage it if you don't mind seeing them all over the glass. Some people actually like them. Also, they are one of the big reasons people go for tissue culture plants. It's hard not to get non-tc plants that don't have bladder snails or eggs on them. my very first tank had an explosion of them and it took about a year to finally get them widdled down in population to the point I hardly see them anymore. I've been very diligent on making sure they don't get into my other tanks.
