I don't know how many beers the Red Sea design team polished off the day they came up with the 'DIY Net Cover' but wow, just wow! I can imagine the stunned silence as someone had to put one together during the pitch to management - If ever there was a 'that'll do, quick to market' product! Spent a frustrating two hours doing half a Red Sea Peninsula 650. Will have to leave the other half until my enthusiasm builds! 'Google's better aquarium net cover!'.
