The alk was set to match the stores that I have bought my frags from. They tested my water and had me adjust it to were it is now prior to adding frags. It was much lower. One thing have learned through all this research I have done is ask 100 reefers what parameters work for them and get 100 answer. The only thing that is constant thru all answers is keep it stable. I have the guy coming out tomorrow so if he recommends changing parameters I will. But as I had said the frags I bought came from 2 stores who use the same parameters and at least 1 of them has incredible growth. As a matter of fact one of my frags ... A war coral... I bought 2 and placed one in a high flow spot on the edge of a light and the other on a high flow spot directly under the light have both died. But I went back to the store the other day to get a test kit And the frags of the same colony have encrusted themselves to the shelf they were on... All new growth since mine were purchased and died.... And yes my sea hares are still alive seen them this morning
You are correct. Each guy will talk from its own experience and from what he/she has learned also by reading and discussing. So yes, you will have several different comments.
As you can see in your own home, keeping the same parameters as the store is not working for you. You need to find what works for you.
Nevertheless, there are rules that are equal for "most of the people". I wrote most, because this is biology. You do not have the same setup as your LFS, hence mimicking the water parameters is not working.
On top of that, it is very difficult to have a tank that will grow happy SPS indepently of the specie. Real life, most of the time, is that some SPS will grow under your conditions and others not. I live with that. It is better to find acros etc, that survive your tank that adapting the tank for each one.
Just my view
And going back to the ALK point. I will recommend you subscribe to Reef Central and read the SPS forum. You will find that most (always most because this is biology) reefers with ULNT use ocean Alk levels. Of course, you will find some exceptions too.
All the best !!!
