great answers thanks guys
So basically kalk will be helpful for LSP no softies right ?
Also im still confused about ruining GFO/CARBON reactor may do something to corals ?
does anyone knows what this about ?
Kalk is an alkalinity and calcium supplement. So it will help everything in the tank, not just LPS.
Carbon cleans your water chemistry. it also absorbs all the chemicals your corals produces when they are not happy. Carbon will absorb all it can absorb and then start releasing. So you need to change carbon every 2-3 weeks. GFO is used to absorb nutrients in your tank. It will prevent algae growth. It helps lower nitrate. Using too much GFO may lower nitrate too fast, thus hurting the corals (parameter change too fast). GFO particles that accidentally released into the tank may kill inverts. So be careful with them and flush 2 gallons out every time you change them.

when you say check alk level, lets say its dropped what should i use to bring it back up ? kalk or 2 part dosing ? if its not much i can do it manually instead of buying dosing pump,i don't like too much technology in a tank cuz simply more devices can fail . making more mess,also i read about geting right size skimmer instead of going bigger ? is that true ? does anyone experienced anything bad with bigger skimmer ?
Kalk or 2 Part depends on you.. smaller systems people prefer kalk. When tanks get too large and certain element get drained too fast, people use 2 part to supplement. I just use 2 part. I dose Mag/Calc/Alk to the exact level I want.
I would HIGHLY recommend an automatic dosing system if you can afford it. 3 reason:
1) It is much more reliable than your hands. Depending on your tank size, a screw up in dosage can really mess with chemistry. Corals are hardy but inverts don't like it. Buy a good brand like APEX, or Bubble Magnus if you are afraid of failures. And even IF they fail, your water changes should help balance your chemistry.
2) Auto dosing allows you to go on vacation. Just saw you want to take a trip for 2 weeks a year down the road... would you trust your parents or siblings.. or friends to come dose your tank?
3) Do you really want to hand dose for years to come? daily job if not weekly.. depending on amount of corals
Bigger skimmer is good, but not too big. I recommend up to x2 your tank size. This way, when you upgrade tank size, you can reuse skimmer. But if it's too big, it will clean your water too fast, leaving no nutrients for your corals, so bad for corals.
