I split the max dose into 2 smaller doses during the week. I leave the skimmer off like 5 hours. Not exactly sure which bacteria they primarily use but it doesn't require fridge and it really clears out detritus. Even my sump fuge is clean now.That's weird, wonder what's up with the site. I'll definitely get the Probio - I have used PNS substrate sauce starting up my tank because I was really impressed with the company.![]()
