So ive got a 65 gal tank that i broke down and rebooted 2 months ago. And it seems like this new environment is perfect for vermetid snails, and they are booming. So im gonna break down the tank again and eliminate them for good!!! With some hydrochloric acid. Ill be going through the whole tank, and sump, even cutting out the over flow box to throughly clean that. My questions are 1) How long should i soak the rock for? and more importantly how to clean the acid from the rock! 2) Sand? Ive got a lot of it, am i going to need to do anything with the sand or can i just toss it in a brute can for a couple days? It is my largest source of biologic. 3) Is it possible for vermetid snails to live in high flow areas such as inside your plumbing? If so, ill be replacing those also. 4) Any other steps that im missing for elimination? Let me know, thanks
