I bought a new PH meter. My old one was taking longer and longer to get a reading. I take PH reading each day I wanted to have something that was faster.
My old salinity meter on the right works great and was very stable. I like it a lot so I bought a PH meter made by the same company.
So far this one seems better. It is more accurate not that I really need it to be. So far it is much faster.
Here is my lettuce still growing
I took my shop vacuum and put a small air line hose on it. I used this to suck out most of the fine solids. This worked out very well and I did not get rid of that much water.
I will be putting in a new fine filter next week.
