on your signiture it says u already have a hydrometer !!!!
that is for SG
(although unreliable )(portable refractometers r spot on)
dont even bother with alk
and i keep my SG
at 1024...permanantly.....(even for water changes)
just test amm ..nitri..sg
for now..is all u need until the cycle is over....
when amm and niti = 0 (took me 6 weeks)
then test nitrate..(which will probably be high)
hit with a huge water change..get a nitrate remover in your filter media
leave another week...test again..hopefully u be good to go )
then u can test PH
...phos...(good fun huh ?)
hope this helps your testing question
good luck and enjoy your hobby )
