It's been a week since I started cycling my 230 gal and the ammonia is still high. Does anyone know how long does it take to cycle a big tank? I use polyester fiberfill in the sump (There is Hypo-allergenic on the label and nothing about anti-mildew). Does it safe to use this polyester fiberfill?

I changed the water, added aquarium salt and fungus medication, the 2 white dots are slowsly going away, but it is still weak and it starts eating now. This one is not wight caught. I had it in the same tank with the wild caught and discus about 2 months. The wild caught one is fine. I will try prazipo and see.

have lot of oxygen in the tank

I had two altum angels and several discus in a 60 gal tank. One of the altum angels started breathing hard yesterday, I tested the water and the ammonia is a little bit high so I moved all fish to another tank (good water condition) and the altum angel is still breathing hard, the rest of the fish are fine. There is a white dot on the altum angel body, doesn't look like ich, a little bit bigger than ich. What should I do? Please help.

I am cyclying my 230 gal tank and using anti-mildew agent polyester fiberfill in the sump. Should I drain the water, replace theanti-mildew polyester fiberfill and refill the water or just replace the anti-mildew polyester fiberfill?

I am new to this, first tank with overflow. How do you determine the size of the overflow? by volumne? Does anyone know where can I buy a big piece of filter sponge for sump?

I have a 230 gal and 80 gal sump, want to buy a water pump. What water pump should I buy? and flow rate? Thank you.
