I went out and got diatomaceous earth from home depot. Didn't know there were 3 different grades until after I put in and some one on this forum told me pool grade after I already put in. I'm sorry I'm starting a new thread if I shouldn't be but now my husband is a little upset with me and I'm scared it could harm us. So I'm looking for what to do now. Was so excited about getting a pool and now I'm regretting it. Seems like I keep messing everything up. I'm shaking inside
