Hi all hope this is right place I have change my system to a new and bigger one it has been going for a year now still learning about testing and parameters and need help with my new test kits ive done 2 tests
1/3/12
salt 1.025 temp 79, alk 190, hagen test around 2.9 with red sea phos under .25 API cal. 660 API mag n/a PH bluish guessing 8.0 red sea nitites amonia 0 nitrates.20 or less

1/9/13 salt 1.024 temp same 79 alk lower 160 phos lower 0 cal lower 540 MAG over 1500 done with salfert, ph same 8.0

I have done a partail water change using reef crystals salt and top off with rodi system and cleaned protien skimmer between test

now is my mag test so high because my cal is over 500 and what measures should i take to correct my parameters every one seems happy but i do have some eccess alge but seem to be getting better

Ive also been watching alot of vidios and thinking on investing into the hanna test its they seem to be much more easier to read any feed back is most welcome thanks
