I’m new to saltwater but have already experienced more equipment failures in 2 weeks than years of freshwater fish keeping. So far I’ve had an ATO float that was defective out of the box, reef90 power supplies overheating and this morning a rattling powerhead. Oh and my original return pump was supplied with all the wrong fittings. Is this sort of thing normal in this hobby or am I just unlucky? Makes it a very expensive hobby to say the least! Feel free to share your experiences so I know I’m not alone!
