Hola Roxana,

When I searched for "Puzolana" in Wikipedia I found Pozzolana.  Is this what you are refering to, or something else?  Apparently pozzolana has high alkalinity, which might interfere with maintaining the proper PH in an aquaponics system.

Our aquaponic system is almost ready! We are going to use as the growing media a volcanic rock called PUZOLANA. Thanks Farmer Brown for your advice!

I asked to the people of Tajo La Florencia about Puzolana as you told us. Yes the value of the square meter of this type of rock is almost 8000 colones ($16). This material has been used in hydroponic and fish tank projects! I would like to know if somebody had used puzolana in aquaponics systems

Roger, Construi un tanque en concreto. Lo repelle con un material para uso marino.  Tengo fotos y videos aqui:  www.farmerbrownsaquaponics.blogpsot.com  aunque no e subido updates recientemente.  Tambien tengo algunos videos en youtube.  Use tanques para alimentacion de ganado hechos por Eco Tanque, que son "food-grade" para las macetas de piedra e igual para las de "floating raft".  Tengo dos de peidra y tres estilo floating raft, mas una mas de piedra en una tina reciclada.

Hola todos. I'm in Turrubares, near Orotina, and have had a 4,000 liter backyard system going for a little over 18 months.  Anyone is more than welcome to stop by.   I am using Tilapia and growing lettuce, herbs, and peppers.  Would love to know if anyone has had luck with spinach and brocolli, which I have not mastered yet.  Recently started trying rucula, which seems to do well so far.  Would like to switch to a fishless system that relies on red composting worms to create the amonia instead of fish, which are enrgy intensive. Anyone done that?  Worms process more food, by weight, than fish, and don't die when air runs out.  Thanks.

We are planning to grow Azolla which is an aquatic fern that has a symbiotic relationship with bacteria that  produce Nytrogen, you might know about it. Azolla has been use as a fertilizer on rice crops. It will be as tilapia food and extra nytrogen! do you have some experience with this aquatic plant? 

Also in facebook I found a place calle Aquaponics Costa Rica. There are at least two people working in this kind of project in Costa Rica. In the one that is advertised  in Guanacaste, they are growing soldier flies for feeding the fish. it´s very interesting!

Hola Roxana, lo que recomienda el libro que tengo es 1kg de pez adulto por cada 40-80 litros de agua. Yo fui a ver una finca en Florida y ahí usan menos porque no quieren vender el pescado. Todo depende de lo que quieran ustedes, si quieren comer Tilapia tienen que tener más peces.

Saludos y suerte, ahí me cuenta :)
