I had origionally was using 18 as my minimum FC level dont let it drop. After I found that my CYA was lower then 20 i was ok with the 18 level. Now that I have added some CYA cuz the sun was eating it all i moved up to 20. I boost to 30 and dont let it drop below 20. It still needs some more CYA but i will wait till im done with SLAM.
I also brush floor and walls everyday.
I check FC in morning and add to get thru the daytime. Check again after work add again to get thru over night. I lose more during day then night by atleast double so I know the sun is still eating some. I think my CYA is around 25 to 30 now. Ill test it this coming weekend.
Sounds like we are both doing the same thing with the exception of the SLAM level. I started at 16 then bumped up to 20 then to 24. For a week nothing happened. Finally starting to see some small changes since sunday but still very slow. I think I will bump to 30 and see what happens.
