Simply go through the thread since it contain more details and thought process!Forgive me for not reading every page of the thread. But based on some of the dates and pictures. You had a pretty quick turnaround. Going from all dry rock aquascape to acro sustaining in mere week/couple months. What did you do to get the tank mature enough so quickly to be able to avoid a year of abysmal growth and STN while sponges and microfauna build up. Even after a major rescape in a mature tank, I’m set back months on acropora health until things stabilize again. And that experience doesn’t seem to be unique to me. Happens to lots of people. What steps have you taken to avoid all that
However in short, I dosed plenty of biodigest and a shot of vodka prior the tank was filled, induced a bacteria bloom, got skimmer for aeration into the tank until filled and used strong UV while skimming. Used only dry rock for low bioload. Kept dosing Biodigest. Measured still no ammonia and no Nitrit, hence cycle hasn't started. Then I brought my Nitrate reactor back online and dosed again Biodigest, Nitrates and Ammonia chloride to feed the bacteria of the first and second part of the cycle and watched closely the nutrient levels and kept populating the bacteria. Second day I placed some Montis and Tenuis into the tank as canary. They made it through ;-) Tank behaved well, Nitrates dropped quite fast so after a week I brought all my remaining corals back in. I could have done it earlier but had to lower ALK a bit first.
So I measured ALK three times a day while bringing the Calcium reactor back online.
Some Corals had experienced TN already while in care of others due to certain circumstances and stress.
So this TN basically stopped mostly while ALK, CA,MG,K as well as No3 was stable.
The CARX was difficult to adjust and to keep ALK stable. Swings I did see immediately caused some minor progress on TN but stopped as soon the ALK level was stable again. I tried to do changes over days if possible on all possible parameters.
Only Dry Rock was used to avoid too much bioload from Liverock.
Only a few Liverock pieces came in with the Corals when I got them back into the tank.
Also I run continously a considered larger UV unit to manage bacteria blooms and pathogenic bacteria control.
Oh, yes.... I kept dosing Biodigest and after corals were in and Nitrates kept dropping, I stopped ammonia dosing.
Honestly one thing I should have avoided earlier was to allow the tank not to exceed 78 deg F !!!
Well I did do this later and installed some Cooling fans to use Evap cooling for the tank.
Cooler temps will reduce risk of pathogenic bacteria bloom hence reduced risk of coral infections/diseases as well help to prevent bacteria blooms.
I guess thats it!
Keeping everything as stable as possible and do changes slowly on Chemistry.
And use a good foundation of bacteria strains ;-)
