sontdo Posted January 26, 2008 Share Posted January 26, 2008 I just found one my emerald crab dead. Not sure why? Does anyone know if the water condition or what other factor causing its death? My return flow to the tank pumps out very fine bubbles, making the water to look slightly hazy. Does anyone know why this occurs? Is it a air leak in the hose system?(scratch) Quote Link to comment Share on other sites More sharing options...
coker98 Posted January 26, 2008 Share Posted January 26, 2008 Air could be seeping in from somewhere in the line unless it is new. New plumbing usually has a few air bubbles that need to work their way out in time. About the emerald crab, the same applies to it as does all inverts. Good water conditions are a must. This means very low ammonia and low nitrate levels. I dont think slightly oxygenated water would kill an emerald crab. Hope that helps.

spectra Posted January 26, 2008 Share Posted January 26, 2008 Emeralds can be weird I have had one die and the others just keep on moving around the tank. I used to have a few in my 90 one did die but not sure why. The others are still alive and doing great. As for the bubbles maybe there is a small hole in one of the lines. Bubbles in the system means there is air getting in there somewhere. Just need to find out where they are coming from. Quote Link to comment Share on other sites More sharing options...
andy Posted January 26, 2008 Share Posted January 26, 2008 You might also be drawing larger air bubble in thought the pump intake; the pump then thrashes them into microbubbles. Check your sump for too much flow or bubbles from the skimmer's output... Quote Link to comment Share on other sites More sharing options...
sontdo Posted January 26, 2008 Author Share Posted January 26, 2008 thanks for the tips. Finding air leak will be tough. I'll start from the sump. Quote Link to comment Share on other sites More sharing options...
CCR Posted January 26, 2008 Share Posted January 26, 2008 If there is any in the intake side, IE piece of shell cheato rock frag, etc. t will cause your problem. I found this out the hard way. even replacing a pump. matter in the line is the first place to check. Quote Link to comment Share on other sites More sharing options...
