I am following along I have a low iron glass tank from Tank Me USA no problems so farI know this is kinda old now but curious to know if there was any more development into what may have caused this?
Currently I have an aqua one aqua reef 400 (don't persecute me for it was my first tank and didn't know any better) for around 4 years now and it has done the exact same thing over the last 18 months on the front panel which is also low iron.
I have just started a build on a new 8 foot tank with low iron glass and a little worried that I shouldn't go regular glass incase it is something I am doing to cause this.
