As long as the fishes are not "blow away" that it show be good. Have a observation for a day or two before more adjustment . Too much major adjustment will cause undue stress to your precious . Cheers
If you followed the instructions , it meant to be used immediately after dissloved . It turns cloudy if you left overnight . I always adjust to 1.025 and used it immediately
I had 2 lionfishs as my first fish. Getting it to feed on frozen market prawn had always been a real challenge. 1.5 Feet is good enough for even 2 lions. Just ensure you have a feeding one and good skimmer. Cheers
