Well last night i made giant leaps for octokind an stuck all me pipework together and had the first full on water test, whhooo hhooo!!! :D All went like a dream except i forgot to put in my return ball gate and there was a minor dribble leak from the connection within the pipework and glass between tank and sump. nugget here forgot to load up with mounds of sealant underneath an only put some on the pipe stickin to the top of the glass in the weir. right im wafflin. This may not seem big to you but ive been lookin at a dry tank since the end of september, so wet glass is lookin really sexy at the mo. hence the pic -sumthin to look at!!! Obviously need to do away with some glass on the top an open up with mesh or whatever for gas exchange an put me equipment in the sump (some got some not). But any comments would be most welcome :D :D BTW how far from your glass at the top do you reckon you should have your water line, mines only 1-2cm an touchin some cases...hmmm ???
