I'm trying to clear my SP as much as possible so I degassed with a wand on a drill. I thought it was good. The other day, I added Sparkolloid.. it cleared pretty good after 2 days, but there was a slight haze.. I also read that if there was any gas in the wine, it might make it harder to clear.. Now comes the vacuum pump.. so I've got an HVAC pump... after speaking with a member here, I rigged it up ... I tested it last week and it worked well.. I went ahead and decided to do what would happen on a wine that was already degassed with a drill attached wand. Look at this..
