Thanks guys just did a res change. I will discontinue using silica, using Power si that shit is good stuff, a little expensive but good.

Most the time silica doesn’t work for me. I try sometimes but for the most part I don’t use it. 🤷🏼‍♂️

I used to be able to when I mixed by the feed, along with a ton of other additives.

Have since gone basic. Jacks 321 and that’s pretty much it.

Can’t say I’ve seen a difference with or without, but I like the idea of the potential increased stress resistance.
