I agree, but for some poeple there it is not an option.+1 Phil...even though I'd suggest to never medicate your display.
Never mix equipment from a quarantine tank with your display because cooper from quarantine can get into display from equipment. You can clean equipment with vinegar bath with city water with chlorine it will get rid of the cooper in equipment but having 2 sets of things you use like salinity tester,nets,siphon hoses shouldn't be crossed from tank to tank.+1 Phil...even though I'd suggest to never medicate your display.
I will only use Aquaclear filters on my seahorse fry tanks! They are awesome! The pump seems to last forever. Occasionally it doesn't want to start back up after I turn it off, but a good cleaning always gets it up and running again.Best filter to use is an Aquaclear because of the easy fit sponge media they use. They are like $5 for 3 of them.
