Hello ! and help,please! I should have known,I now have new lights,Ehiem ECCO, UV light,florite substrate,glass top to keep cats from swimming while ''fishing'', new plants.:icon_lol: Right. The other day did some work on the tank,slopped water, towel dryed tank and injoyed how it was coming. ..... The next AM turn on lights I see water on the corner seem. The old tank now leaks. Slow leak,about 6'' from the top.Leak is a leak. I need a new tank. Now my question is what brand of tank is good? or bad? I have read also that black caulk is stronger then clear,read somewhere Perfecto has gone down,AGA is now Aqueon, told at LFS that AGA is low end Marineland ! Oceanic tanks look awsome but I would guess that they are out of my price range. Any advice would help... fast:help: I forgot 55 gal leaker, would like to upgrade to 75 gal.
