I normally poo-poo premade stuff, but the price here isn't bad, quite good really, considering the effort saved, considering even the modest cost of buckets, the price of net cup lids, the air pump and the odds and ends of fittings and tubing.

I'm a firm believer in the ease and simplicity and lack of debris from LECA. I personally like Geolite for its random shaped balls, which I think has benefits, and for its relative lack of dust.
