First, top up your KH to desired level.

Second, test KH after a few normal water change to get an idea how it drops with your water change. After a few tests, you should have a rough idea how much to top after each water change without testing.

Hi Vinz, i took out some water sample from the tank, it's clear in a white cup ... so it's not green water. But the reason for the cloudy water is due to a low kh and the plants not taking up enough nutrients?

Is it advisable to add in fertiliser sticks now? the tank is 2 months plus old.

No.. KH shouldn't affect your plants directly. Given your readings of 6.8 pH and 1 KH, your CO2 is very low. Check the KH-pH-CO2 charts and set your KH, pH and CO2 levels properly. Recommended is around 6.8 pH and CO2 at 30ppm (I'm aiming high since your pH is lower with TR7. This should bring you to around 20plus ppm). Determine the target KH from here.

My advice is, fix your KH, pH and CO2 levels first, to make sure your plants have enough CO2 to photosynthesise. For all you know, it may be indirectly the cause of the cloudy water.
