I have recently acquired a Red Sea Max 130D. I have a few concerns and wonder if anyone else has had similar issues. The first problem is that the inner lamp wiggles itself loose from its fitting after every few openings of the hood. Now I have pushed it in as far as it will go but to no avail, it is tedious task having to open the acrylic cover to re-insert the lamp. The second problem is the protein skimmer - it is awfully noisy and not very efficient compared to the Aqua Medic turboflotor and even the Tunze nano of my other systems. I am of the opinion that the convergent-divergent flow chambers of the RSM skimmer is a flawed design as compared to simpler constructions. Otherwise a quality system with decent looks to boot.
