Casey - Randall,
Thank you for your input. I am not sure what is going on, but I do know it is back to the 6.4 - 6.8 range depending on the time of day. Whatever happened happened, as along as it stays in that range I will be a happy camper. Fish and plants are both thriving. All except for those Shiners that I put in about 2 weeks ago. Just about every morning I get one more dead Shiner. The goldfish however are having not difficulties. The stupid tomatoes plant do not realize that the season has long been over and they keep producing; determinant variety an all. Only one plant to give it up has been a cucumber plant because I left one ready to be picked for longer than I should as it was hiding in the growth. Now it is time to get ready for the fall plantings. Thanks guys.
This was a great thread! This had many suggestions - I think I counted 17. The one I settled on to help keep the PH level up without adding chemicals every few days is the "Limestone River Rock"
Any suggestions on where to find Limestone River Rock?
I tried Lowes - no luck. I google this and no luck.
Perhaps called something else in NY?
A bit back in thread I had mentioned how rainwater was whacking my system. Now that I have buffered my system with Barn Lime (Calcium Carbonate) it just stays at 6.6 pH come rain or come shine. A few palms full and she has been steady ever since. I dumped it in my sump and I can still see remains in the bottom of the tank that gets used up as the system needs it. I no longer have a problem. Nor have I had to add any for about 10 days and sure it will continue as is without tinkering. Since barn lime is like 2 bucks for 40 lbs at Tractor Supply it was certainly economical and very easy to do. I started another thread about acid rain to as not to divert from the original Dagmarvelous thread here.
