Hi all, I've been in the process of collecting all the various bits of kit together to start my 1st salty tank - It's gonna be a sumped 180 vision, After various questions and advice on here, I 'Had' decided on a twin standpipe with a corner weir in 25mm pipe. However when I came to drilling the tank and cabinate, I found the pipe work wouldn't fit in the corner configuration due to the frame - (Don't want to mess about re-designing the cabinate), And a squar or rectanguler weit, takes too much room out of a small tank..... So back to the drawing board ! At about this time I came across X-Aqua's X-inout, at around £120. but can't find anyone who uses one - nor a UK stockist, I also came across a thread on another board about 'an Ultra Thin Weir' This basically is taking the twin standpipe method- but substituting recrangular 'glass formed' conduits built into the bottom and back of the tank aprox 15mm x 100 via low profile bulkheads - instead of 'classic 25mm standpipes'. This takes only about 25mm from the 'front to back' width (?) and abit from the bottom which would be hidden by sand anyway. Anyone got any thoughts on this ?
