Hi, I'm new here after reading this topic quite extensively, but I didn't really come across any conclusive results regarding what I would like to attempt. I haven't owned a fish tank in over 15 years due to various reasons, and have recently gotten back into the hobby, so consider me new to the whole process again.
I have a live planted 240L (63G) tank and would like to remove all traces of Bladder Snails, Mini Ramshorn Snails, and their eggs. I understand their benefit, but it's something that I'm not going for within my aquarium - it isn't out of control, but it's unsightly at times, even when feeding much less than I used to.
Assassin snails aren't an option as they're illegal in Australia, and I believe Pakistani Loaches may have trouble with my current stock based on what I've read.
Over the coming months, my plan is to cycle a small quarantine tank (40L-80L) that I want to use for sick fish, or when my livebearers are giving birth to keep them separate. After it's cycled, I want to transfer all my current fish to it temporarily and perform RR on my main 240L tank.
How viable would RR be to an entire tank?
Would this process destroy the beneficial bacteria of the main tank, and need to be cycled again from scratch?
As I would need an absurd amount of carbonated water to cover 240L, would I be able to drain the tank to the halfway point, let it sit for a week to force snails and their eggs down lower, then use 120L of carbonated water to destroy them and their eggs?
Or, should I take another approach, such as alum or copper on the entire tank? I don't plan on keeping any snails or other invertebrates in my tank in the future.
Any input would be appreciated so I can at least get an idea on where to go from here.
