I have a 36gal. seahorse tank that ive been running for alittle over 2 months after the water cycled. I was told to add macroalgae with seahorses that it would help with nitrates and give the seahorses a few perches to grab onto. I put the algae in 3 days ago and now the levels are going nuts real high nitrites and nitrates and lowered my ph down to 8.0. fixed the ph problem real quick but does anyone know a healthy way to bring the levels down. really need some help. I have read a bunch of ways but always better to hear from someone that has a proven way
