Hi Tom and Co.,
I was wondering what to do. Since I have to start performing 50% water change according to the Estimative Index, I will do it with a hose. It is much easier and faster.
My problem is chloramine. I will of course add the water back to the aquarium through the hose.
How do you condition the water, since the tap water enters the tank? When using the bucket I would condition the water first before introducing it in to the tank.

I was using Estimative Index method in my low light CO2 injected 180 liters fully planted tank for a couple of month now, but did only 20% water change.
Yes I have lots of Thread algae, Green Beard algae (trimmed by the SAE) and Staghorn algae. Little BBA on Java Moss (SAE trimming).

I am off to buy a hose now.

Regards, Dusko.
