No3 still at 0. And this week PO4 also zero.

Something is taking in all the nutrient although I had started dosing KNO3 since 16th Aug.

Can it be the hair algae?

May 1 is public holiday in Singapore.
So has time to fillup the tank with DI water

Get this salt for my new tank. AF Reef salt

For the 2.5 footer AIO tank this is 4 months no water change

PO4 0.009
NO3 0

Need to dose NO4 and PO4 to bring up the nutrient level.
Too low for my liking

This 2.5 ft AIO tank has no skimmer . Never dose iron or carbon also. Only running on refugium
