mg/kh problem

[barthsimson]

i am not adding anything fr kh. but i am adding marine buffer for ph. it says it will increase ph and kh. but my kh is still same. ph was 7.8. it increased 0.2. right now it is 8.0. and my system is about 11 weeks old. i am not changing the the water bi-weekly. i am changing every week around 10%. also i dont have any corals. i am just trying to get the right water parameters for the first corals or mushrooms. never done anything for strontium yet. i ve just heard (from an aquarist, gold aquarium in calgary) i dont have worry for the strontium right now. he said after i add any corals,mushrooms, i shpuld worry strontium, iodine and other trace elements. but i ll give it a try how you said globaldesigns. 15-20 % water change in couple days and take 1-2 days off and try test the water again. thnks for your help guys.
