Sixline gone :(

[banditpowdercoat]

Well, come back from camp yesterday, to find my Sixline missing. Can't see him anywhere, or find the body. Tested params this morning, PO4 is up, 0.1. This tank never has a PO4 problem. Overflow is blocked by eggcrate, so I dont think he got in there. He didnt allways eat at feeding time though. Allways energetic, but not allways out at feeding. Bummer. Making water for a change now. If I can't get the body out, how long approx for elevated PO4?
