I'm glad you asked me that question, I was getting worried there for a minute. I think that making sure you have the proper ph, not one that is just close will make a difference. Which of course is the reason I bought the tri-meter. I have mentioned a time or two, what we need to do is concentrate on getting the 7 basics right, First.
And here is the tri-meter, along with a couple of things I use to make it easier for me. I quicly discovered that having it laying down was not convenient. They had these little red trays at Menards, work great and the plastic container is perfect for keeping the probe wet. Always use 'fresh' water in your little container.
This is the process I use. I check the ph, ppm and temp of the fresh water. Since I now know what the ph of my 'fresh' water is, I can use this to make sure my probe is calibrated and operating properly. I set everything in place on the table I'm going to work with. Check ppm, Ph and temp. Before I added the 3 1/2 gallons of water it was @950ppm. Our ph while 'in range is not 'spot on' and this needs to be corrected.
We will add a teaspoon of ph down, check again, 5.9, better, still not right there, another 1/2 teaspoon ph down, mix it with a 'wooden spoon', check it again. 860 ppm, 5.8 ph and water temp of 18c/64f.
I think I am getting things in balance and a few points difference in ph does make a difference in hydro. Thanx dbb. VV
