has anyone ever used these before? I would like to use these in combination with my philips coralcare gen2s but i dont know if it will be able to support them since they almost way 15kg together above a 4ft tank. before i spend a fortune on these mounts for them to bend...
Also what size would fit a 4ft tank best in anyones experience?
