Hey everyone so I was wondering if anyone took water straight from the ocean and used it unfiltered in their aquarium and if so what effects did it have on the aquarium I have seen results from a guy that I know that does that on his reef tank with everything looking great and was wondering if anyone else did this? And yes I have been to his house to see his tank in person and it looks amazing. That shocked me when he told me he did this and I would have never guessed that an aquarium can look that amazing of natural salt water dumped straight into an aquarium like that. He also have acros and other sps corals that look amazing and their growth is crazy they all have a lot of white around the edges in which the skeleton is calcifying he said that they have been growing like weeds since he started doing this. So I wanted to see if anyone else did that and how successful it was. All of his softies and lps look great as well and fish are looking like they came from the reef as well their colors are so bright and vibrant so it has me curious. And he does have tangs as well that look totally heathy and not a single tang flashing in all the time I was there.
