These kind of remarks are absolutely unnecessary for the good tone here in the forum. I feel sorry when seeing such unfounded attitude.



I did the aeration using a simple silicone tube which i pinched many times with needle having previously sealed its end. Its important for the reason of evacuating the air bubbles that form when anodizing and moving the water to equalize temperature faster. The tube was connected to small silent air compressor with regulator , but any compressor from fridge would do, in that case a way should be found to vent out the unnecessary pressure build up .
