Just purchased 1 hydra 32 AI and I was wondering if anyone could give me an advice as to what settings to put it on. It will be going on a 90gal tank. I’m still putting it together I purchased it used and resealed the whole tank. I still have to clean it a bit more but I will do so when I test for leaks I will put some citric acid to be able to scrape all the left over junk in it.
