Hello arapaimag,
Hope you are well.
How often does someone go inside the tank to scrub down the inside part of the viewing glass?
Thanks.
Actually I have not needed it cleaned by anyone inside the big tank. I have a very powerful magnetic cleaner made for 1" glass. When the panels do need it we just use the cleaner. My friend Jeff Mountjoy has cleaned the 15,000 glass panels from the inside (Once three years ago). The plecos do a fair good job in both tanks.
I hope you where OK when Irene hit your area.
