I have a few things that I took off my 40B that im not going to be using anymore. I bought this white Hydra 26HD new less than a year ago & only ran it at maybe 20w at most. The Tunze 9004 has some marks from these small white worm like things I have all over my tank but other than that works fine. The will come off with vinegar soaking and scrubbing but I just don't have the time. The 24w Green Killing Machine UV sterilizer was used for maybe 2 months and has the same white things on it as the skimmer does. REASONABLE OFFERS CONSIDERED & PRICES INCLUDE SHIPPING.
