Dec 5, 9h52: bubbles entering in the first pre-filter, flow feeding too small for the strength of the pump. Stop underway to clean the "boite a vase"
	the boite a vase was ok, but I found 2 large pieces of plastic in the SBE38. The flow was still not good so I changed the SBE38 intake closer to the boite a vase and lower in level to maximize intake from the clarinette. Flow is now ok on both circuits
