So, I am getting ready to build a 225 reef tank. I have been deciding what to do for a sump. This has been a tough decision, the last tank was a 150 and I built an acrylic sump from scratch, it came out great and worked very well. I am still considering this; however, the cost of the acrylic is almost as much as the cost of a trigger sump that will support this tank. So I am looking for input regarding Trigger sumps or others for that matter. As a side note I have about a 36 gallon sump that came with the tank that I will be using for a Refugium. The main function of the sump will be for marine pure blocks, skimmer, heater, dosing and return pump. Thanks for your thoughts and inputs.
