my tank capacity is 500 liters. i use filtration from deadrock.skimmer and kaldnes. I am acropora growth growth and most of the LPS. I don't use a large 3 measuring device because I use a 50 liter water change system every day with air coming in and out every second. What I'm worried about is that my Big 3 level won't be able to keep up with what's being absorbed by the reef? please input thank you every 14 days I take the air around the uninhabited beach. I keep air in the air reservoir by providing an aerator to keep the water moving and not hot. and I also want to ask if I should take a dose like amino or not? thanks.
