oh yeah...cost will be more. We had a 135g cube a few yrs back before our daughter was born, but I got too busy to maintain it. So rather than let it get nasty, sold off livestock and equip...looking back, should've kept the tank. But thats hindsight...never been big on it. Im sure Ill post the plans as I work out the kinks, took me 1.5yrs to finalize my last tank. Hoping this one moves a little faster.
