I will have to consider that. I have certainly learned a lot over the past 4 years and may have not gone the AIO tank if I was to start over. Either new tank or getting out of the hobby entirely.

But back to the repairs: Cut out the offending silicone or apply fresh silicone over it?

If I have to drain the entire set of rear chambers I will apply silicone over the entire old silicone while I am at it.
