How often is your tank water being turned through the growbeds?
Who are you asking this of?
If me, that is hard to say. Each bed is different. One is very slow and takes probably 15 minutes to fill up, one is very fast, probably fills ever 4-5 minutes, and the rest are in between.
The total volume of your fish tank should be cycled through the growbeds once an hour. If this isn't happening the water isn't being filtered enough, and could explain your constant high PH.
Just a thought on what may be causing you guys difficulty with PH.
More than enough. I have about 800 gallons with a 5000 gallon per hour pump, and 6 ibc halves for grow beds with only about 20 tilapia. I would guess less than 1000 gallons per hour is being diverted back to the tank, the rest is going through the grow beds.
