I came in and got to work.
Initial readings on ammonia were 8ppm or higher since it was the last color on API test kit.
I drained about 40 gallons of water and replaced it with tap. I don't have a RO right now but I put some Stress coat in the bucket as I'm carrying it. I also moved my tank a little to allow for a higher water level in the grow bed. So in addition to the 40 gallons I replaced I fit another 40 gallons in there. My back is killing me lol. I skipped on the hose for today because I just need the money elsewhere.
Did another ammonia reading and I'm still between 4-8ppm now but it's better than a strong 8ppm. I won't feed the fish for a couple days and see where it goes. No deaths since last night so that's good. Fish are swimming in what appears to be a healthy manner.
So I used the formula to figure out the amount of salt in the system. Guesstimating that I'm around 1.5ppt now after I dumped the rest of the salt I had on hand. I only had 2lbs of salt to start and some was already in the system and guessing 180 gallons of water or so would weigh 1400lbs. 2lbs to 1400lbs gets you 1.42PPT unless my math is off.
My Nitrates were at 10ppm today before water changes which is probably an off reading. I might have not shook the bottle enough or something. I can't see it going down at all right now since there is nothing growing in there. My lettuce is still in a propagation tray.
I'll update the thread tomorrow or the day after with more readings and hopefully I'll see some decline in the numbers.
