Hi Mal. :wavehand: Welcome to Reefcentral.
I do not think protein skimmers are bad. I think that protein skimmers can be a trigger for Gas bubble Disease in seahorses that are predisposed to it, due to the enzyme carbonic anhydrase that regulates the amount of CO2 in the tissues and the blood. IMO if you choose to use a HOB skimmer fine, if you have repeated bouts with GBD, you should remove it, or move it to the sump. IMO it is best just to leave the protein skimmer in the sump, which is where mine resides most of the time. I have attached it to the tank when I was having pump problems, and before I had a sump.
