Great feedback! Yeah, totally forgot about the carbon reactor. Thanks for reminding me.....currently the reactor is in the main display running rowaphos thats why, but only loaned it from a friend, will have to get my own. haha. There's ample room for the reactor in the sump still.
I have 2 return pumps in case one fails on the return section. But wont be plumbing it in until i go overseas, to prevent calcium build up.
Will be using my 2ft tank for qt.
At the moment, i got a small side refugium which im planning to just throw my remaining cured rocks in to grow pods or a section for frags. But still indecisive if i should put a frag rack there. I guess we'll see in the long run.
Pretty satisfied at the moment with the sump size, as there's ample room to place my cr and co2 tank within the cabinet with a top up reservoir by the front. Thanks for the suggestion kkk121, definitely worth considering but maybe at a later stage.
Btw, i love ur joined system. will consider setting one up as well, and use my secondary return to power it.
