<p>We have a system near Albuquerque and we have had all sorts of problems with PH issues. What finally tipped us off that it wasn't the rocks but the water was a wonderful gentleman on this site who told me about how much acid he was adding daily due to the water in the Phoenix area to main PH. I should have known that - I grew up there! </p>

<p>Well, at some point you may need to add something. I suggest keeping to a pH of 7 (or, neutral) which may require you to either add an acid (Acetic Acid, or vinegar; HCl; HF; and so on) or a base (NaOH, this is very strong; Calcium BiCarbonate; Calcium Carbonate, sea shells/egg shells; etc.). Buy some pH testing solution from a hydroponics or aquarium store and follow the directions. Remember not to move the pH more than <strong>.1</strong> per…</p>

<p>Chris makes a very, <em>very</em> good point Mike. You should ALWAYS stock according to your bio-filtration capacity, and NOT your fish tanks water volume capacity.</p>

<p>That is a good rule of thumb assuming you are at the least a 1:1 growbed to fishtank volume ratio. That is indirectly 1lb (or 1-2fish) to 5-10 gallons of growbed (or filtration volume). The volume of water is important, but not as important as your growbeds capacity to filter the water.</p>
<p></p>
<p>FYI 7.5 gallons in a cubic foot, so 1 cubic foot of growbed to 1 fish (with a grow out weight of 1lb) is an ok rule of thumb I have seen TCLynx mention before. I like that rule the best.</p>

<p>In dooing some reseach, I read that <span style="color: #01598f; font-family: 'Trebuchet MS','sans-serif'; font-size: 10pt;">A good rule of thumb is to stock about 1 lb of fish per 5 -10 gallons of water, or 1-2 fish per 10 gallons of water. Never stock more than 1 pound of fish for every three gallons of water. Should we go by this, or the pounds of gravel and plant material?</span></p>

<p>Mike, both those compounds are pH buffering compounds... you may have to use them as such, depending on your pH...</p>
<p></p>
<p>And certainly some Potassium and/or Calcium boost is beneficial for plant stages of growth... and required if you have deficiencies...</p>
<p></p>
<p>But if your pH is high... then you wouldn't use either of the two compounds to address a deficiency issue...</p>

<p>Mike, the pea gravel is your filtration. I assume you mean 18 grow trays that are 11inches x 31inches by ~6inches deep correct? 18 of them at 11 feet long would be a lot.</p>
<p></p>
<p>So you should have 42sqft of grow space and @ 6inches deep, 160 gallons of pea gravel. </p>
<p></p>
<p>160gallons of gravel filtration is how you want to gauge how much fish you can handle. The real question is, is 1 gallon of gravel per goldfish enough? That will depend on how big they plan on getting.</p>
