Back from vacation problems
So, I was away for 2 weeks and had my brother in law feeding and topping off while I was gone.
Pitfall one - somehow the heater was unplugged and my water is now at 76. I guess I just need to slowly bring that up. I usually keep it at 79ish.
Also, by the looks of it, he was overfeeding. I got back yesterday and my glass and sand is covered in algae. Not really a huge disaster. I'm going to do a blackout and a few large water changes to get things back in check. I'm going to test Nitrates today, but I'm sure it will not be pretty.
But, the real problem is - I fastened eggcrate to the openings of my canopy. I have a zebra moray, so instead of placing eggcrate over the top which blocked out too much light for my taste, I nailed some eggcrate over the openings. It's been working great. Well, somehow - while feeding - my brother in law tells me that a nail fell out of the eggcrate. Basically, there is a black coated metal U (staple-like) nail somewhere in my tank. ****ed if I can find it.
So, my question is - exactly how bad is this? Maybe it's not a huge deal - but, I figured I'd ask. I know there should be no metal in the tank, but I'm not exactly sure why. Does this highten the danger of electric shock, will it negatively affect water chemistry? I'm going to use a turkey baster to blow on the rocks to see if I can find it, but I have about 170lbs of rock and a 4 inch sandbed - it's not going to be easy.
Thanks, all. At least nothing died.
