Hi,
I had a 1.2m x 450, 750 tank. Wife bough me a 1.8m x 500 x650 for my birthday. So I moved the tanks around and kept the sump and refugium as is to maintain filtration. Started well for first 2 weeks then all the corals closed up. No fish issues, but starfish is gone and sea urchin seems on its way. All corals not doing well at all. Here is the specifics..
main tank 1.8m x 500 x 650.
sump 1.0m x 320 x 500
refugium 900 x 400x 500
1 x 5500l/h up pump
1 x 2500l/h up pump (Connected to 10Watt UV)
2x Skimmers (Queen and Prizim)
2 x Wave Makers (SunSun 3000l/h)
4 x 80Watt T5's
2 x 39Watt T5's
Ph 8.1
KH 9
Calcium 450
Magnesium 1600
Salinity 1.022
Temp 25
Phos =0
Nitrite =0
Nitrate = Of the scale.
Corals:
Frog spawn
Torch
Hammer
Various Mushrooms
Candy canes
Bubble
Star Pollyp
Have done 100l water changes 4 times from last week Saturday. One chamber in the sump was filled with bio rings and used allot of bio balls in the other 2 chambers. So I have removed half the bio balls Wednesday, and removed half the bio rings today and cleaned the middle chamber and added 2 kg of Seachem Pond matrix to the 1st chamber and replaced 1 lair of bio rings in the second chamber and moved 4 bags to the 3rd chamber to try and spread the rings so that muk do not build up again. I have been adding Special blend daily and have been adding Red Sea No3PO4-x daily for the last 12 days. I also moved the corals to the refugium and disconnected it form the main tank, this unfortunately did not help. I also added a nitrate reactor with sea chem denitrate stones in it, this has been running since yesterday.
Here are my questions,
1 How long will the 2kg Matrix take to be affective as I would like to remove more bio balls and bio rings? (less in the sump, so easier to clean going forward) The 2kg treats 800l
2 How long will the de nitrate reactor take to be affective?
3 Do I move the corals back to the main tank as I thing the issue is in the refugium as well?
4 Any ideas to speed the posses up?
Any advise are welcome.
