After more than 6 month trial of the 1st prototype, today a second unit was made. It is using plastic pot as the fish tank which is larger than earlier porcelain pot.
This set will be further tested for few more months then I will make it for others. That stand is temporary, final product the stand will be outside the fish bowl.

First and second prototype, undergoing actual test to ensure trouble free operation. Ideal small unit for apartment, condominium, town and link houses. This set is also suitable for growing Strawberry using aquaponics method.
