Hello and I'm in a bit of a pickle. I'm in the middle of a 20% water change of my tank ( ) during a cycle of my neon tetras and I will be doing a water change every 2 days. However, after removing 48 litres from the tank and dumped 42 litres down the drain, saving 6 litres to clean my filter tomorrow. I measured 12 litres with a measuring jug and put 12 litres of tap water in a bucket. Before I added the water de-chlorinator, I need to add 1.2 millilitres of it to the tap water, but the measuring cap for it only starts at 5 millilitres which is very inaccurate. My ammonia+nitrite digester also requires 1.2 millilitres and the measuring cap starts at 1 millilitre which is a bit more accurate. Can I put measure the water de-chlorinator in the ammonia+nitrite digester cap? Is there any other way to measure it accurately? I need help ASAP please. Thanks.
