Ok gonna share alittle info that seemed to work for me. I couldn't find how much baking soda to use to raise my ph so i'd like to share how much i used and how much it went up. my ph when i started was a very low 6.0. Last night i put about 1 table spoon in. my pond is around 2300 gallons. This morning the ph was 6.2. So i added 3 more table spoons and checked it 2 hrs later, figureing my pump turns the water over in that time. when i checked it after the 3 table spoons it was about 7.0 to 7.1, and stayed there the rest of the day so i added 2 boxes of crushed oyster in nylon stockings in the filter. I couldn't find how much of the crushed oyster to use either. each box is about 4 ounces, biggest i could find at petsmart. And now for the pictures.
