hey, the pics of the pavers are from when I first did africans and was still in school finishing my degree.. I was not allowed to work or they would hold my license... so I had to get cover for cheap... It worked well... now I put more money into my setups... I had only had the setup for two months and only had the fish for 3... Heck I did not know mbuna and tangs should be seperate back then.... so chalk it up to being a noobie... I do not do it now... it was WACK... now my tanks look a lot better.... ask a few of the indy people...like repair or rallysman... I know what I am doing...
