hi i am Massimo from italy, i have an 300lt discus aquarium with a lot of plants. Yestarday i have broken mi ada diffuser so now i need do replaice it. My idea is do use an co2 reactor like the dupla reactor 400 with an dedicade small pump, how many litres pump i need and if is an good product or there is an better alternative. Thanks to all for the suggestions.

Here is a good DIY reactor that works very well:DIY internal Reactor, great for Yeast CO2 users!

thanks i will try to make one maybe it is best that many reactors on shops

You might also consider a simple DIY PVC pipe external model.
Cost: about 10$ and add a pump that will add 300-400 gph, or 1200 liters/hr to make sure there is enough flow of water.

You can use an Italian to the English translator engine then back from English to Italian to double check to make sure you have the right translation.
