Hey guys. I'm new to reef keeping, I originally had a 30L nano tank but with what I want to put in there, we quickly realised we needed something much bigger. Since upgrading to a 150L (in which I have a bubbletip anemone, two ocelllaris clowns, a banded shrimp, a saddleback puffer, a psychedelic mandarin, a large plate coral, a bunch of duncanops and a brain coral and a strombus snail), we bought natural saltwater to fill it, as well as got 200L to store for water changes. My question is, I have a refractometer, and in my baby tank I always had my sg
at 0.026 like everywhere suggests, but when I tested my natural saltwater (which is taken from the coast along our GBR in Australia) it is 0.03 sg
. As this is natural water I don't want to tamper wih it by adding freshwater, and everyone seems happy at 0.03 - I acclimated them all over two weeks ago and no one seems stressed or different, and the corals are all bright and blooming/colourful every day.
My question is should I try pulling this back to 0.026 or just leave it? I'm inclined to want to keep it at natural levels, I just want to make sure it's not going to hurt anything in the long run.
