needle valve
That bubble counter/needle valve combo definitely has design flaw. Remove it and replace it with a needle valve from JL's http://www.jlaquatics.com/phpstore/s...ct_ID=cr-pnval
then build a small bubble counter out of acrylic. quite easy to make or buy one retail.
no problem since for me.
