Question On Snails

[Geoff1991]

Well, 15g tank. When its cycled i want to put in 6 harlequin rasbora and 6 sterbai corys.

Im also thinking about snails, but as ill be stocked rather well, i was thinking will the snails make too much of a difference?

Im wanting 2 zebra snails and one apple snail, one maybe one zebra snail. Do they create a lot of waste?

Also, my pH drops to about 6.4 - 6.6 during the day with my co2. Will this be a problem for their shells?

snails in my experience add very very little to the bioload. especially if heavily planted. ive got dozens of snails in my 6 gal planted tank that is fully stocked with fish. and all's well. as for thier shells with a low pH, depends on the kH and how much carbonate you have in your water. if low, you might want to consider adding buffer like crushed seashells (or clam shells which is what i use as they are loads cheaper than crushed coral, and you get a yummy dinner out of the clams to boot)...if low carbonates and low pH, their shells will suffer for it...but again depends on that value whether or not to add buffer.
cheers.
