So Im starting a new grow and taking a break from coco. I decided to do another RDWC run because Ive liked doing them in the past but its been some years since my last time. I bought some bulkheads and pots from PA hydroponics and pieced together the rest. The total water capacity is about 50 gallons including the reservoir. Im getting ready to drop 4 different strains... Anvil, Black Strap(breeders reserve), Kaleidoscope 2 and Strawberry Cheese.
Ive spent the last week dialing the environment and water in before I start the seeds and stumbled across a weird issue today. I monitor the pH and such with the guardian and have secondary pens for redundancy. I hooked up an old chiller I had sitting in the garage yesterday and noticed the pH climbed a full point over night. It hadn't done that all week. While it did climb, it did so very gradually which from what I remember is mostly normal. Without boring you with the details, Ive narrowed it down to the chiller. When water circulates through it, the climb in pH is much more rapid then when the pump feeding it is off.
The chiller is a JBJ Arctica which I used to use in a saltwater aquarium like 10 years ago but as I said, its been sitting in the garage collecting dust. I pulled it inside 3 days ago, cleaned it off and ran a mixture or H2O2 through it for a few hours and then spent the next day flushing it with regular water. I figured this would kill and/or clean out the insides so it would be good to go. When its disconnected from my setup, the pH is relatively stable. When water cycle through it and my sump the pH climbs quickly.
Has anyone ever encountered something like this? Could it be a bacteria issue? The only other thing I can think to do is to cycle a solution of bleach through it and flush again and try again... thoughts?
