Thank you I’m going to check them out!Salifert for everything apart from po4 for that I would go Hanna checker 774 as all the tests for po4 are next to impossible to get an accurate reading imo as the colour charts are so hard to read for po4.
Some will recommend hanna for alk and nitrate, I would only go for those options if you hate reading a colour chart, the alk is very slightly easier to do with the hanna, no more accurate and the nitrate is good but the reagents are on the expensive side, definitely more accurate than salifert as the pink colour chart is not easy to read but nitrate is not too critical, so many are happy with salfert but hanna is definitely worth getting for nitrate if you have a little extra money, alk checker I have but went back to salifert, the reagents for the alk checker can give different resding depending how old the reagent is and how much is left in the bottle and also from bottle to bottle.
I’ll start off by trying out Salifert ammonia//nitrate/nitrites during the cycle process.
