I’m just wondering how long does the blade last everybody? I only use the blade, the plastic one doesn’t work for me. I also leave the blade in the tank and wanted to know how long it lasts, before it needs to be replaced.

It all depends on how often you scrape, and how much algae build up you have, and how good the blade was in the first place. I had some blades last over a year and some go bad after a few months its hard to tell so I just keep 1 spare on hand.
I’ve used the same blade for year and a half. Most of the time, I just use the scrub pad side. If calcified areas, I use the razor side. After use, I rinse under tap water and towel dry it. Sits next to tank when not used.
So you don’t keep it in the tank?
So are most people not leaving this in tank at all times?
After 12 months kept in the tank and used every few days, mine still seems perfect. I only use the blade side. Also the tank glass hasn’t been scratched. So I’m pretty happy with it.
