troubleshooting alkalinity

[support@proline]

Hi Shaun
I have to agree with little silver max ,you can get salifert or even better you can use an Elos test kit ,Golds carries both or you can just take a water sample to them & have them test it,however a reliable test kit is very important ,specialy for KH & CA.
Also keep in mind that the tank is only one month old @ the early stages & cycling ,minimal Ph swings are expected ,you have the bacteria trying to break down nutrients & get stablished ,in the process a lot of oxygen is used,....
What are the tank inhabitabts @ this point ?
Also would it be fair to say that your kalk dosing ratio is higher @ night?
