LF Skimmer Advice

[jostafew]

Hey everyone, I'm currently battling an algae / cyano problem that's going on about two years. Granted my efforts were pretty half ass early on (new house, other priorities) but long story short it's been a long haul. The system itself is about 4 years old and in that time there always seemed to be some form of nuisance in the tank whether it be cyano, algae, dino (that sucked)... I feel like it's been an uphill battle for way too long based on other people's experiences and I'm starting to question my equipment. Right now my system is 50gal total volume, display tank is shallow so I'm light on LR / gal, DT has fine sand bed, light bio load (6 small fish, inverts), very few corals at the moment sadly... The fish are not over fed, if anything they could be fed more. Water comes from a 5 stage RODI which at its worst was showing 1ppm on the output side before changing all elements about 6 months ago.

I used to run carbon in a TLF150 reactor but now I run Rowa in there to attempt to correct the current issue. Skimmer is a Remora Pro with the Mag 3, I skim wet (tea) and I might get a quarter of the collection cup full after a good week. In my mind something just doesn't add up, if excessive nutrients aren't going into the tank via food or water (or salt), then the only alternitive is that they are not being efficiently removed from the system which brings me to my question; should I be considering a different skimmer? I have a sump and the Remora hangs off the side of that saving space, and I got it for cheap way back when so I've just run that. Now though I'm thinking about trying to pick up an Octopus NWB-110 or something like that to see what it'll do in my system because my Remora has never produced a lot of skimate and nuisance algae has almost always been a problem (much more recently though)...

I've done a lot of reading (both in print and on the web) and I don't think I'm making any big mistakes, yet the issue persists... I'd appreciate any thoughts on the matter and whether I should try to find another skimmer, thanks in advance
