Planted Tank Obsessed

TX Holey Rock and ph parameters
I have a nicely established (4 months) that is heavily planted, it has 2 older (read at least 5 years old) tube style lights and an LED, the tank has water changes of 40% to 50% weekly. No CO2 (yet).
The rainwater is collected in 275 gallon IBC water totes. I tested the water at a local lab where I had worked at a few years ago and the ph was 4.6 (ouch) The water is pumped into the house and then filtered and heated to aquarium temp in a 35 gallon Brute trash can.
I had 8 guppies in the tank, 5 males and 3 females. One of the females has given me 4 youngsters that are happily swimming around like champions.
This is where the story goes sadly awry, first one of the females died. It happens no big deal. Then one by one all the adults apart from two males and the fry are all that is left.
After checking the water in the trash can from the vats and the ph was right at 7.0. Checked the aquarium and it is at 6.4-6.6. The only difference I have made is I placed a piece of TX holey rock into the trash can to bring up the ph (said he hopefully) three hours later as I said it is right at 7.0 and the tank is lower as per above.
Am I imagining things or is the piece of rock really going to make such a drastic change within three hours?
I am wanting to add some Corries and maybe a couple more female guppies but I do not want to have them die on me within 48 hours.
As far as I can see all the other parameters are within spec, suggestions are more than welcomed.
Take only pictures, leave only footprints.
