Okay, I know NGT hate other NGT with a passion. Im getting a 3" NGT from Wes. What are the chances that 2x 3" NGT in a 75 with 4 other IT will get alone? I hear NGTs grown up together from a previous thread got alone fine.
I don't think there's a chance in heck it will work. Sorry, but i don't think the mix you have now has a chance of working either. I would decrease the number of dats not increase
