I have a 47G AIO tank. I feed two cubes a day as I have four fully grown adult fish and a mandarin dragonet that eats frozen food. I currently have Reef Octopus skimmer and a Tunze 3182 MAR - so it is an algae reactor with a volume of approx 3 gallons allegedly meant for tanks 132-450 gallons. While this does grow chaeto well my nutrients are still high as evidenced by the algae covering every surface. The tank is only about a year old, however, almost all of the rocks came from my previous AIO tank which was 3 years old. While ideally I would feed less, thats not an option for my case. I am considering purchasing something like a Santa Monica algae scrubber to throw in the back where I can find space. Before I pull the trigger on this expensive purchase I just wanted to see if anyone else had thoughts or advice for improved export. TIA
