im using jbl test kits for all.so far so gd. some ppl prefer sera.IMO i find they r not very accurate.....one of the best test kit is from seachem.very accurate but very ex! kel has them.
if u keeping corals then get calcium test kit...if not dun bother. u got all the impt test kits liao...not need to get more. maybe po4 if u wish to keep algae blooms in check
