So it seems I have a bit of dilemma here or not. Looking to get some opinions on what the best option would be in my case. I have a 20 gallon long diy sump I put together with pre-made baffle kit. In the last chamber before the return I have some bio balls and chaeto. Thing is the chaeto is just kind of mushed in there with a subpar light. So it's essential serving no good purpose. My question is should I just remove the bio balls (since I have nowhere else to put them) and dedicate that change to chaeto or keep the bio balls and remove the chaeto? Which does everyone think provide the most benefit to the system?
