Well I did 3 days of Lights out, 1 of actnic only.
I took the vacuum cleaner attachment that is used for the end of the hose, soaked it in vinegar for 3 days. Took my hose I use for water changes added a few rubber-bands around it, to make a good seal INSIDE the adapter. Took the hose and ran it to the sump, into a filter sock, and just scrubbed away,.
That is why the glass has SO MANY drip marks. I was like... you know.. those that understand what I did will not have a problem with a few drip marks. (LOL)
It only took me about 2 hours to slowly and painstakenly go through and scrub it with the long bristle adapter and get sucked up into the hose.
I have a few more spots to go. The RBTA did not want to move so I did not do that one section.
