<p>If you are seeing sudden jumps in pH. Take note of the time of day of the different readings as well as algae. If you are getting low readings near dawn and high readings in the late afternoon, then algae could be causing pH to swing. I seen algae blooms that will take the pH up to 9.</p>

<p>A large top up or water change can also cause big pH changes. Take note that you might check the pH of your tap water right out of the faucet and get a low pH reading but that will be a false reading since CO2 trapped in the water in the pipes/underground etc will act as a weak acid and give you a false low reading. When that CO2 has a chance to escape while flowing around the system the pH will come up to it's actual buffered level.</p> My plants look great now so t…tag:aquaponicgardening.ning.com,2012-02-01:4778851:Comment:2863792012-02-01T13:27:09.515ZBenicia Bendelehttps://aquaponicgardening.ning.com/profile/BeniciaBendele

You want to dose on water volume, not growbed volume. Dosage will be highly variable depending on the algae conc. of the system, so unless you have a lot of fancy equipment that I can't afford, the best way to dose is hit a baseline and then watch your plants very carefully and respond to nutrient deficiencies. Or, if you're commercial, do tissue analysis and respond. That dosage rate is based on my experience. It should help hit baseline on a per gallon basis and then allow you to drop your rate and respond as plants begin to show deficiency. You don't want to over dose, but more is better than less when it comes to iron. In populations with high populations of algae, your iron will dissapear fast, and much of it will become plant unavailable in the process of algal assim. and decomp.</p>
<p></p>
<p>While you initially dose on a per gallon basis, down the road as you expand your plant production you'll want to switch over to a steady biomass basis for dosing- again that depends on watching your plants, tissue analysis, or water testing. Water testing is not great though, I'm not sure most testers can separate ferrous, ferric and amino-bound (chelated) iron in tests, so the best way to monitor is 1) tissue analysis, 2) visual deficiency monitoring, and 3) water testing. . . Any way, I'm commercial so I choose to stay ahead of the curve and dose at a steady rate that works for me.</p>
