hi.. im in the process of setting up my first reef system and im now got to something im confused about! so far my tank has been running for about 3 weeks now and ive done the basics live live rock mh lighting good water circulation and skimming. I live in an area that has soft water (i do use ro) and im finding the ph has a low initial level which needs to be buffered. the effect in the tank is that the ph raises and drops from 8.05 to 8.19 over the daily period. Ive been advised that to correct most of the ph issues along with the calcium levels im going to need to keep sps i require a calcium reactor or to add a kalk stirer? does anyone which would be best for my tank? advice please tnx...
