I imported this wonderful & likely very rare Bubble King 650 External from Klaus around 10 years ago. The craftmanship on this brand of skimmer is unmatched. It worked perfectly & likely the best thing I ever invested in for my system. It would remove pounds of skimmate! Among all the amazing benefits it helped correct the bio-load, nuisance algae & nitrogen cycle. Used for about 1 year before I moved & closed down my 2500 gallon + system. Cleaned & kept in perfect condition. Hoping someone is in need of a skimmer of this capacity for their system now or in the future. I prefer not to ship this item but rather a local pick-up. It's large & I can only imagine what the cost to ship​/​crate would be. I live in the Fort Wayne, Indiana area. Please, serious inquires only. No trades, etc. Please message me for more details.
