Bruce :

Did I detect a second walmart special chinese RAS \:D or just a spare tank in waiting. Good to hear the YP are doing well. When I used to clean my BG aquarium (with out draining)I was concerned with cleaning the sides and leaving or letting the side growth stay in the aquarium even though it was filtered. I used a cheap siphon when I cleaned the sides to get most as I scraped it off. I did that by starting the siphon and holding it in one hand while I scraped right above the intake. It worked fairly well. I don't have any idea if that was necessary. ewest
