PH keeps going down no new nutes or water

Ok I have a 20 gallon RDWC system with expanded clay for media using tap water. It has been running for 3 weeks. The original nutes were dyna-gro and hydroguard and my ppm was around 800 with tap water. About 1 week ago I flushed the system because the ph was 4.5 and I had nute lock out, pale leaves on top. I flushed with tap water for 36 hours, my tap water is around a ph of 5. I restarted with fresh nutes and added dyna-gro protect to raise the ph. At 1st it worked like a charm and I had a ph of 6. I checked ph 5 days later and the ph was 5 again. I added protect again but the ph was still up there. I had not added water or nutes. My plants look fine again but the dropping ph has me wondering why.
 
Thanks again for posting this. I wanted to get the information to a new(er) grower, and rather than upload my copy, I just did a quick site search for yours, lol.

I hope you are still healthy, and are able to get in a ride now and then.
