Algae scrubber better or no3,po4 remover additives?

[Bacteria]

Pls advice?

Algae scrubber. If built correctly with the right size, it will be very powerful in removing both no3 & po4 at the same time. Apart from having to clean regularly, there will not have any costs involved. 100% natural too. Also running reverse photoperiod, algae scrubber can help to minimize the impact caused by ALK swing. More nutrients will be recycle back to the display tank for corals to feed on if u do not intend to run protein skimmer. There will be no harm if u plan to run protein skimmer alongside scrubber.
