Hi all, and thanx to viper357 for the welcome. unfortunately i posted in the chat box instead of the forum... so lemme start again... I have 2*2*0.8 (L*W*H), with a lab room with dimesions of 2.5*1*2.5. All my piping runs underground as i designed my house with my tank as a full 360 degree viewing b4 entering my living area. unfortunately, by listening to bad advice, n not doing my own research, afta 1.5 yrs, my tank is nothing but a SaD excuse for a reeftank. I had a 2.5*0.5*0.8tank before which settled beautifully... when i moved i decided on my current dimensions... Luckily i was saved from dumping my tank afta a visit by my daughter's preschool class, and as i was xplaining to them abt the ins n outs of my tank, i somehow realised i would b nuts to give up. So here i am, gna redo my lab, n gna get my tank to wot it should be... and the best thing i could do is join the forums... First thing i am gna do is get myself a new skimmer preferably an ATB Elegance Giga skimmer, n upgrade my profilux II to profilux III. Luckily i found sum1 that is a software developer and also into setting up reeftanks.... So wish me luck... And oh yeah... ANY ADVICE will b greatly appreciated....
