<p>Being in Miami, you have access to 3/4 inch Stalite at Conrad Yelvington, if you want to use it. There is much discussion about it on this site already. </p>

50 liters is 1 3/4 cubic ft, so if your 16 sq ft of GB is 1 ft deep, then you have 16 cu ft, requiring 9) 50 L bags go straight hydroton. If you want it for a 6" top coat, then half as much, or 4 1/2 bags. If you want it 4" deep, then 3 bags. Etc.

3/4" drain rock, no fizz, from a rockery not a lumber yard. Around here, the cheapest round river rock sold as "drain rock" is already washed and screened for size, and delivered to your driveway. <br />
<br />
The red that washes off lava rock is just lava rock dust, and is not harmful to fish or plants. Don't sweat it. The cloudy water will settle in a few days and lava is a great medium, though again I'd opt for the larger 3/4" size if you can find it.

<p>Make sure you bring a glass of vinegar when you go gravel shopping. Look for a quarry to get it on the cheap. Take a few samples of the stone candidates and put them in your vinegar.

<p>Make sure you bring a glass of vinegar when you go gravel shopping. Look for a quarry to get it on the cheap. Take a few samples of the stone candidates and put them in your vinegar. Watch for bubbles. If you see them, try something else. You want to find an inert rock. No limestone! River gravel typically is a safe bet but is pretty smooth. If you can find something more porous that may be a better bet but I wouldn't sweat it too heavily. Really depends on the type of system you are building for any slight edge you may get. The river rock has the benefit of also being very easy on your hands for digging around in. Lava rock = not as fun.</p>
<p>Maybe call some building / contractors and ask where they go for theirs gravel. It should not cost much at all.</p>

<p>I am reading reviews from some who have said that the red washes off of these lava rocks! That can't be good for the plants or the fish. Why can't I just find ordinary lava rocks that won't harm my system?</p>
