Okay, just bought a used 80 gallon and I have a couple quesitons.
1. I noticed while cleaning it, there are two (not deep) surface scratches on the inside, bottom pane of glass. Its not a crack, just surface scratches. Is that something to be concerned about? Not sure if it makes weak spots in the tank.
2. Came with a UV
Sterilizer. I've never used one before. Do I really need this? I plan on starting a FOWLR
tank with plenty of lr
, and in-sump protein skimmer, if that helps.
3. The tank came with a drilled bottom and pvc
pipe leading to the top as an overflow to the wet/dry. My question - the pvc
pipe is open at the top. Should I be putting something on top (some kind of screen or cloth) to cover the hole, or just let the water go through an open pipe? Seems a little odd open like it is.
Thanks all. This is my second sw
tank - last was successful but no skimmer, no lr
, no RO
water - guess I got lucky. Want to do it right this time.
