well i just finished your article in ReefKeeping from 2002. thanks BTW, very informative. i work in construction and do some PVC things here, but what i was wondering (because i have never seen it in the pics of reefs) is the purple primer used on the joint safe for reefs? im in canada, so maybe we use a different product, buts its a purple acoholish (?) smelling primer...
thanks in advance
