good morning, i made a revamp to my filter system after getting a cheap 2nd hand fgt box filter...

this is how the whole setup looks like, not a very tidy setup i know, but i am more concern abt my fishes and the water quality...

3 main sections, the tank, the fgt box filter and the blue tub at the bottom...this will be my main tank, still the same as usual, housing a silver aro, a motoro and 2 irwinis...this will be the new 2nd hand fgt filter that i got, running a tom800 from the blue tub at the bottom into the inlet...here is the tom800 located at the corner...these are the medias in the 3 compartment fgt filter, mainly biohome...i placed the fgt filter box at the side as i did not want to add pressure to my main tank or cover the tub which i intended to keep some fishes...

so this is what i did, as the outlet is located at the bottom, i placed a 3ft OHF below to run the water from the outlet into the blue tub...and this is the outlet flowing into a flower pot with medias inside as well...

the white piping is overflow water from the main tank using a DIY overflow system...and lastly, my blue tub housing 3 payaras, 2 brackish moray eel and a black ghost knife which i think has been swollowed by 1 of the moray...
