<p>Thanks...I will say the tap water we use has a base pH of 8.0. Well lets see with the bed, it already contains 5 cuttings, 2 tomatoes types (Grape and Roma), 2 hot pepper types (jalapeno and Portuguese), Basil and seeds of 2 types of lettuce as well as several bush bean seeds.<br></br> <br></br> <cite>Jonathan Kadish said:…</cite></p>

<p>pH 8.5</p>

<p>The tank is only 20 gallons feeding a 10 gallon tote with 5 clippings and and assorted bunch bean seeds and lettuce seeds. There are 5 large Comet Goldfish and 2 small Comets in the tank. Lots of oxygen as well as an O2 injector on the drain line. The Ammonia has remained at 1 since a week after it was shocked. Any thoughts on what to do to get water to 7.0-7.5, I am assuming this is why the Nitrite/Nitrate is not changing. Thanks in advance for any advice.</p>

<p>it took my small system over 9 months before the ph dropped from the nitrification process, and your ph will drop as well (as long as your media is neutral).. with a system of 7000 gallons (nice!) it will take a while but it will drop.. 8.2 is fine for cycling, and most fish won't have any problems with it.. you may have to provide your plants with some micronutrients, but that is much easier (and less stressful to the fish) than trying to change your ph</p>
