Background: I am revitalizing my set-up, as I wish to have more demanding corals on my reef. It has been running more or less on its own for 10 years,- but now it is time for an upgrade.
Set-up: 200 gallon aqua, in the large overflow box there is trickle filter with bioballs (no filter before), 20 gallon sump, boobleking skimmer with automatic cleaning, nitrate filter (sulphur) and fosfate filter (rowaphos). Ozon when redox <300. Traditional Balling supplement via dosage computer. High circulation in tank. Light, 3*120 w LED (aqua light), 2*15 w Blue LED. Feed with frozen artemis, mysis and mixed marine. No other supplements. Change 10% of water once a month.
My question is on whether to replace my bioballs (been in there 6 years) with other material or LR or what to do. Struggle a bit with too high nitrate, which is why I turned on the nitrate filter recently.
Input please,- Thank you
