Hi everyone, I will be starting a new SW tank soon. I've had some good advice about getting running (the tank was used before so I will be giving it a good clean with vinegar and running polyfilter). I have been advised to drill the tank and use a sump (ditch the trickle filter in the hood). The problem I face is a partition in my cabinet which serves as bracing also it seems. I really dont want to mess with the structural integrity of this cabinet. but will do if need be. My idea was to run two sump tanks on either end and drill the partition. I've made a revised plan (have been advised to use 2 drains between the sumps in case of power cuts etc.) Thoughts and comments are welcome as I want to plan this out correctly. Tank is about 300l and partition size is about 45cm Long x 38cm Width x 57cm height on either side. So perhaps 2 90l tanks?
