Hello guys
First I would like to apologize for not updating the topic, it was bad times for the system, I'll make a brief summary of the events.
As I said before, everything started with the fixtures update, I was running RapidLed Onyx with great results, then I changed to RapidLed Coronas. I dind't realized how powerfull they are (I dont have a Par meter). So, I burned many many corals, for a year or more, and I was thinking the light wasn't the problem, now I know there was too. Then low nutrient and high alkalinity, then fisrt big coral loss.
Then I decied to remove all chinese equipment, changed skimmer, return pump and circulation pumps, I was thinking in low quality impellers, and some tungstenium in he water. Then I did.
New Skimmer Regal 300sss
New return Pump WaterBlaster 10.000
Circulation pumps Tunze and Koralias
There is no Jebao, anymore.
As I said before, I started to dose vodka in the system, 20ml daily, and I didn't realised that potassium was consumed too fast, even with 30% water change monthly, I bought a test, and the potassium was 280ppm. I had a lot of burning tips in the SPS and it could be the lower potassium.
I also wondered if I could have heavy metals in the water, like tungstenium, aluminium, cooper..... but here in Brazil we cant send samples to Triton, so this I'll never know.
I did many water changes wihtout a good result, everything I did din't work.
All the corals were dying, then many options came to my brain, I talked with some friends and then I decided to restart the system.
Exemple of corals dying
I tought the plan was good, but it isn't good enought.
I setup a pool, place all rochs, corals and fishes, my skimmer, one Conona, lots os chaetomorpha.
Then I cleaned the tank, rocks and susbtrate, and started the new layout.
In the 6th day in the pool corals stat to die. In the 7th day I moved corals and fish back to tank, and dosed a lot of bacteria.
Result, just 2 sps survied, and a few lps(my frient took them to his tank to save as more as he can)
Few weeks after that I took back the Euphylias.
Now things are getting better, and I started to add some sps frags. I hope the tank will be as great as it was.
Thats all for now.
Thanks
