Research tells us cone shape is better as it draws the bubbles more vertically with less turbulance leading to greater DOC being trapped.
The site you show is one of the Chinese sites and the reason why Bubble Magus have now gone down the route of official distributors which we signed to last week. This resolves supply, variant pricing and warranty issues (which are rare).
You have a 600L system so the 180Cs is perfect.
Our dealers will have stock by mid to late February
