I cannot say enough good things about Tyler and his team! The Minimalist cover was PERFECT. It fit like a glove...even around my light mounts & overflow box. ZERO effect on my PAR reading with or without the cover.
Tyler is SUPER knowledgeable, not only about making lids, but also reefing. So, as you walk through the process of building a custom lid....he understands what you're saying, and what you might need! In my case, it was "hey, do you need cord cut-outs?" WOW, I hadn't even thought about that!!!
Tylers customer service is AMAZING....I will use TopLids for EVERY cover I need in the future.
