yes, you need to read up a lot on how to keep SPS, by your question above, I can presume safely that you have no inking about keeping sps at all.
Please read up more and learn even more before to even attempt sps, trust me, you will not find success without the proper knowledge.
Dun take this the wrong way, I am encouraging you to better equip yourself with knowledge before to venture down the sps route.
Once you reckon you are ready, I am sure lots of the reefers here will help you as best as possible to start SPS keeping.
Without proper knowledge, you will face lots of problems.
My 2 cents
