Hi everyone, i got a new 500 gallon tank custom built to my likings. and i have went ahead and bought matrix for the sump. but there is many compartments and i would love ideas from you guys on what to add in there for best water quality and less work and check ups. i will be having exotic fish and here in australia fish like arowana, rtgg, rays etc etc are very expensive and cant afford to lose any fish.


i would muchly appreciate it if anyone can put in there ideas for me
cheers !
