has anyone used these, i'm very interested into installing one of those into my new 90 gallon tank i will be doing for tropheus red rainbows. the only concern i have is how it stacks up with the test of time. has anyone had one installed in their tank for at least a year or so. My concern is that algea will grow on it and tropehus will bit the background making nicks in it. plz any of your opinions would be greatly appreciated.
