Great choice for integrating a 'ReefMat'!

Quality built! Only suggestion would be to have better access to 'return section' by having whole area above it 'opened up' - or return section enlarged. I followed instructions for the ReefMat plumbing and did not have any issues- but an optional 'kit' would be a nice addition as well.
