Over the years I have spent in this hobby, I have spent quite a lot on products that were wither totally useless, or products that were marginal. I'm hoping that this thread will detail a lot of them, so that others will not make the same mistakes. Please post about any products, old or new, that you find especially bad, and why you didn't like them. These should be products you actually tried.
Here are a few to start with -
SeaClone skimmers - IMHO, one of the worst out there, difficult to adjust and preforms poorly.
VisiJet skimmers - Even worse than the Seaclone, if such a thing is possible. Simply falls apart when you try to use it.
Air Drier for use with ozone - Only lasts a couple of days, and then you need to bake the media to recharge it. Very marginal.
CPR Overflows - U tube can't be cleaned. Needs another pump to keep it clear of air. If the little air escape gets blocked, and you get air in the U tube, you also get a flood. Bulkhead fittings easily snap off.
Hydrometers - Very Marginal. Glass easily breaks. Swing arm ones get jammed up. Except for lab ones, they are not too accurate. Get the refractometer you really need.
That gets us off to a start. What products do you find especially bad or marginal?
