Palnning to start my 322 with sump tank. Need some advise here. Can someone tell me what additives is required during the cycling period? Strongtium, magnesium, calcium? Besides NO2, NO3, PH & Ammonia, what other tests is required? When to perform the test? Which brand of Test kits would you guys reccommend? Cos I know some tests kits gives inaccurate reading. Though I had my first tank setup about 2 overs years ago which didn't work out quite well and had to give up halfway due to work overseas, lost lots of $$$ now got to buy everything 2nd and really careful.
