so i am using a tank for my reef which came with an extra heater and filter both are topfin brand. I already have a much better filter and heater for my tank. Will it cause any harm to use the top fin filter and heaters too or are these going to cause problems. I’m also thinking of putting both heaters in together in case one of them fails. Are these topfin products saltwater safe?
