Hey guys, I am driving myself nuts trying to figure out what my problem is with this Flood and Drain setup I am running. I am running a bonticare 4x4 table with a 40gallon reservoir under the table. I have a 345 gph pump that floods the table for 15 mins every three hours only while the lights are on (12/12.) I am running GH Flora Duo nutes, I have 2 8" air stones in the bottom of the tub that holds the solution which constantly run. When I do a change I drain the tub and scrub as well as clean the pump and tubing all with a light bleach/water solution. Then fill with fresh tap water that is stored in a 265 gallon container,The water has sat for weeks to evaporate chlorine etc. I then add 60ml of FloraKleen and ph to 5.7 and run that for an hr to an hr and a half. Drain and scrub and clean again then fill with more water, add nutes and ph down to 5.7. after 3-4 days the nute solution becomes very cloudy and stats to have an odor. At about day 5 I have to change and do the above process all over. the water gets so smelly, it smells like fish water. If i missed anything Id be happy to add or if you're missing any info just let me know. Any help would be excellent, I am wasting so much nutes changing every so often. The temp in my room is at a constant 70 and the nute solution stays at about 65-68. I also forgot to mention I top off with a gallon of water every other day and adjust the ph to 5.7 daily. I have 25 plants in 6" netpots with grow stones.
