A chiller or frozen bottle in your res and keep it below 76 degrees at all times. PH will rise if your system is working correctly and your plants are happy. The spike you speak about isn't really a spike, spike to me means in hours not days. What your experiencing "I think" is the normal swing. Here is what you do...PH balance your res at 5.6 and let her go...watch her daily, top up if necessary(PH balanced of course), and once it hits 6.2-6.2, bring her back down. I have found over years that DWC seems to be a lot more stable if R/O water is implemented. JAS
