Unfortunately your corals won't retain their appearance in a non low nutrient system. Be sure the receiver understanding that. I have had people get coral from me and be disappointed from its loss of color and overall health appearance. .
What is your dosing schedule. What products and how much.
What is your current test results? Also potassium. If your checking.
Salt brand?
Sorry to hammer you. I want to understand your system a bit more.
Btw, when you change out the stones leave a few old ones in there to help populate the new ones.
All corals I share and sell will be coming with that as the first point of purchase and I won't be selling any of it without having shared that info with potential buyers. Given the reception the corals have had to zeo I'll be making sure as I would hate for people to be disappointed when things do dull a little.
Zeo dosing:
Bak: 2 drops daily (2 drops three times a week at the moment when in maintenance due to higher nutrients)
Start: 0.2ml twice daily after pumping the reactor morning and evening
Stones: 500ml of stones (I only changed the recommended 50% at the 4 week mark but next change will be about 80-90% as suggested)
Carbon: 200ml changed monthly, next week.
Vitalizer: 2 drops every second day
Sponge Power: 2 drops with vital (don't have any at the moment though)
Bio-mate: 2 drops three times a week, will be dropping it back when nutrients are lower. (Mon, Wed, Sat)
Elements:
Calcium: 22ml a day (I think, I'll check when I get home)
Alk: 30ml (really not sure here haha I'll check again)
Acropower Amino Acids: 1ml daily (3ml a week less than the recommended 10ml but I don't mind)
Measurements:
Calcium: ~430ppm
Alk: 2.5-2.7meq/L
Mg: 1230ppm
Salinity: 35ppm (don't use specific gravity anymore)
I haven't been checking potassium but as I get closer to the next stone change I will as I use NSW and I haven't seen any blues fade yet, only brighten
But I will test it as I know it can be critically important in ULNS.
No salt brand, I'm a NSW guy lol I get really high quality stuff and test before each WC and I've not had any problems, also being a uni student salt isn't an expense I'm looking at yet LOL I realise it might be better but I'm happy with nsw so I haven't felt the need to change yet
Thanks for the tips
and don't worry bout hammering haha I'm happy to answer any questions you've got
