Just 4 months after building my first 20 gallon system, I’m getting ready for the next upgrade. I’ll be shipping all plumbing, pumps, siphon, and rewashed hydrotons from my home kit. The only supplier I can find back home is this guy from aquaponicsgogreen.com and he sells it for P3,000 ($60)/25kg (55lbs). On Amazon, the best deal is $27/40liters (25lbs) with free shipping.
The next build will be approximately 1500 gallons with (3) 48″x40″ media beds and (2) 54″ x 150″ DWC troughs. We may need to add another fish tank to accommodate the grow beds we have.
The photo on this post shows how much algae and gunk the system accumulated after 4 months of zero maintenance. Not bad for not having to do anything. I’m sure the worms helped a lot in cleaning out the excess.
