The system was very easy to install, the instructions were very clear. It comes with all the necessary parts. In 15 min I was done.
You have to wait at least 24/48 hours to see an increase of the CO2. It is central that your water surface is not agitated, so you have to eliminate any air pump. If you don t do it then you will have CO2 lost and the whole system became pointless.
I strongly suggest it; for my 200L it works just great, my plants are just enjoying it, they are going crazy and producing a lot of O2 ( you can see O2 bubbles under the leafs). All this just dosing 15 bubbles of CO2 per min, counted with the CO2 bubbles counter provided.
