Having trouble replying threads on my com, so I’m gonna be using tapatalk Updates for those who asked about the algae reactor. I think pictures will explain it all. After harvest: My personal opinion on this. It does work as advertised. But if I were to choose, I would select a size larger then what is recommended for the tank volume. I Guess it is self explanatory, the larger the reactor, the more cheato u can grow. The lesser u need to harvest over time. Pros: It lowered nutrients naturally, light encourages good growth in reactor. Good if u have limited space in sump or need an external method of nutrient removal. Cons: no after sales service, no spare parts available in sg. Slow and takes time to watch nutrients drop due to limited size of reactor I’m using. The lid uses plastic screws to tighten, opening and closing every month may cause wear and tear which may lead to eventual leaks. Will be nice if any LFS is willing to bring in the paxbellum or the pacific sun reactors. Spare parts should also be made available. Happy reefing. Sent from my iPhone using Tapatalk
