have you thought about putting some sexy shirmp in there with the corals. they are the coolest little shrimp imo and that would be perfect for them. you could probably put three in there and they would love it. just a thought i had while watching this sweet tank unfold. how do you like the premade water? i was thinking of using it on a new tank i'll be setting up and have been having a hard time finding people that have used it.
I have that shrimp on my list of possible inhabitants in my head as it's so small.
As the for the water I love it. I will never set up a tank without it. Everything is perfect out of the box, and in fact you can add the fish right away. I did this when I brought my fish to college. For cycling you add some Biozyme as the bacteria in the water is there, just not in large quantities and you will have a small nitrate peak, not nothing as compared in a normal cycle, do a water change and your cycling is done for the most part. Also the calcium levels are kinda low, but not bad. Just dose a little when you first start up.
The other biggest advantage I think other than it's perfect parameters, etc, is that it's all natural and what's better than the real thing? Your fish just seem so much more happy in it to me. If you wanna try it, do a small test run with a nano tank and see for yourself.
