I have had a 90 gallon tank for just over a year now. I bought it on Craigslist and have really enjoyed learning about the animals and watching everything grow. I have been monitoring the parameters for quite a while. There is never any nitrates or nitrites or ammonia - even after something dies in the tank. For the most part the corals are growing and the fish seem happy. Every once in a while something will mysteriously disappear never to be seen again, but I fear that is just a part of it. I have had some issues with red slime algea on the sand bed, and there are usually a few spots of diatoms as well. I just added a bunch of crabs and snails a week ago and that seems to be helping a bit.
The big problem that I have is my calcium is always around 360ppm, my ph stays around 7.9, and my alk is only about 4 kh. I have tried topping of the water with kalk water, adding ph buffers and pouring in liquid calcium. But nothing seems to make a difference in the long run. I do a 7 gallon water change every 1.5 - 2 weeks. But that is about it. What do you guys think I should do?
Thanks a bunch for any advice, I really love this hobby and would like to make things do as well as possible
