Hi,i just got a 24"15"12" clearseal tank which i intend to use as a q tank,but im a bit suspect as its very thin glass,and seems very fragile,my juwel tanks are very solid,ive had my 180 ltr rio upside down when i was changing substrate-wouldnt want to turn the clearseal upside down,even when i picked it up it made a creaky noise!,i filled it a 3rd and no leaks....yet,any feedback on clearseal tanks would be nice,
