The clover is a copy of the aquaC design. The beckett has specific housing requirements; and does not do as well when attached directly to the skimmer box. I can't coment on that design; I remember looking at the plans and noticing it was another aquaC copy. Since I don't think the aquaC skimmers work very well, I wouldn't bother copying one. Plus, there are some patent issues with aquaC that should be respected.
