Dream large.

Just did a quick conversion of a tank, and it turns out to be about 3300 gallons per tank Looks like four of them in the photos. Total of roughly 13,000 gallons, or about 49,000 liters.
If one tank is used as a sump, in a CHIFT-PIST the remainder is around 9,000 gallons for fish.

What is the water source? Are the tanks empty for lack of water? Rains big time in parts of Thailand. Raft systems would need cover from elements? NFT could get water very hot during warm seasons. What kind of predation of plants or fish are native there?

The dimensions on the land are smallish about 50 by 100 feet.

Any one want to pick up with some ballpark number of fish and plants?
