Well- it looks like the refugium leak was a false alarm - I must have spilled a bit of water on the side when adding water yesterday and it took a while for it to run down and accumulate in the front - no water there today. Whewww!! so today will run tests and post them and hopefully between the new RODI TDS readings of zero, and new salt ( Fritz reef pro instead of reef crystals) my numbers will be good.
