Hi everyone! I've had my Fluval EVO 13.5 saltwater aquarium set up for 5 months but the water has never been crystal clear. There are always tons of little particles floating around, clouding the water. I've been researching a bit and can't seem to find the cause of it apart from my filtration setup. Currently, Chamber 1 has my 50 watt Eheim Jager heater, chamber 2 has the sponge filter with ativated carbon and bio media, and the third chamber has the stock pump. I've been wanting to upgrade my filtration anyways and hopefully if I do, it'll clear up the water! I've been researching about filtration upgrades others have made on the Fluval EVO 13.5 and it seems that almost everyone upgraded to the InTank media baskets. Now my question is, is it worth it to get both InTank media baskets for chamber 1 and 2? And what should I put in them? I've read that most people use filter floss and biomedia. I also saw someone else who put chaeto into the InTank media basket for chamber 2 and made a little refugium. Would a refugium of this size be worth it for filtration? I am very intrigued by the natural filtration methods like the refugium. What would you do to upgrade the filtration setup? Thank you in advance!
