For those who do no sparge, what is the water to grain ratio?

After making the mistake of doing a decoction the first time, I'm thinking of doing 10kg of grain for 50 liters of water in a Speidel I can borrow. As the max is 12kg, it should leave room for circulation.

I did a no sparge yesterday with the 50 liter Speidel, dough-in with 45 liters, and added 20 liters more. There was about 5cm between the water level and the lid. With 11kg of malt, I got an OG of 1046.

used a low and wide box from Ikea, spread out the grains, and sprayed 2% water with lactic acid. First time using a mill. Thinking about a way to connect a pipe from this box to the mill, and make a closed system that can be purged with co2.

I have noticed my lagers now take forever to clear up, since reducing mash oxygen. Which I understand has an effect on clarity, but they don't really seem to ever clear (really just lagers).

Insufficent boil can be the culprit

It could be your fermentation.

I've noticed three things that dramatically help my beer clear up and mature faster (and stay fresher longer):

1) Beginning the ramp down to lager temperature much later

2) Carrying as little yeast as possible into the lager keg

3) lagering warmer

Specifically, I pitch at 6c, ferment at 9c with no pressure until 2-3% extract remains. Then, I allow the pressure in the primary vessel to start building to 0.5 bar. When 1% extract remains, I cool to 6c over the course of 2 days, then let the beer sit at 6c for another day. By this time, I've got 0.3 to 0.5% remaining fermentable extract, and most of the yeast has dropped out. I rack to my lager keg now - the beer is clear enough to read through in the liquid transfer line (but still appears cloudy when poured into a glass). I raise the pressure to 1 bar in the lagering vessel and let the beer ferment to FG at 6c - this takes another couple days. Then, I cool by 1c/day to 3c. I hold 3c for another 2-4 weeks, at which point the beer is clear and ready to drink.
