[Killietalk] Brine shrimp hatching problem

[LeeH920226 at aol_com]

I have been hatching brine shrimp for at least 35 years and have not run into 
this problem before. At least, not very often. This past week or two I have 
had an airline become clogged with precipitated salts after less then 24 hours 
bubbling. I ream out the 1/8 inch rigid plastic tubing every day when starting 
a new hatch. This has almost always, in previous times, prevented this 
problem, but in the last week or two I have had about half of my hatches aborted 
because of a clogged airline. I know it is impossible to diagnose what has 
changed, but is there a sure remedy? Does anyone use larger (3/16 inch) tubing? Is 
temperature a factor? Is tap water hardness a factor? Would RO water (with 
salt, obviously) be advised?
