So my 60 cube is about 2.5 years old now and has been going quite well the last year... Great growth. Good color... But recently I had some STN/RTN. I had another thread on it but I thought perhaps the title was not soliciting any interest so I started another thread.
I had about a month or so ago lost a colony of Strawberry Short Cake. Well more like a large frag... I thought nothing of it as everything tested well. A week or so later I notices some STN on my copps hoek colony, grape juice colony, two out of my three bonsai colonies and also my frogspawn looks limp on one side. I hadn't changes or added anything in months. I see no bugs. My LED lights have not changed. I did change out my GFO about a week after the first colony. But I added the same amount as always and had been running GFO from day one.
Then my Ultimate Stag melted in a day. I did manage to save a large frag, but it was a huge colony and made me quite angry. I took the GFO off line, began 20% water changes twice a week, and threw a small bag of carbon in the sump, just in case something needs to be filtered out.
It has been several weeks and I thought the necrosis had slown down but I really has not. My frog spawn looks worse but only on one side. Looks like it is getting blasted by a pump, but that frog spawn has been in the same spot for two years and has grown out of control. Nothing new on that pump either...
Today I took 80% of my copps hoek and dumped it in the other system to try to save it. I checked everything I removed for bugs and saw nothing.
Here are the parameters:
Nitrates 0-.02
PO4 undetectable
Alk 7.0 (where it always is)
Mag 1440
Calcium is up from 450 to 535 (See below)*
Potassium 460 (dosed weekly for 2.5 years)
PH 7.8-8.4
Salinity 35
Temp 78
I have backups for every test kit. I tested my refractor with an old hydrometer and they match. Tested my apex temp against a stand alone thermometer and they match. Apex PH against a test kit and they match.
I dose Phols XTRA daily (have been for two years) Brightwell AA (for two years as well). However I did notice a little Cyano so I cut back on these about a month before to just a couple times a week. But I doubt that is it. I also dose phols Coral Snow and MB7 to fight the cyano. It works quite well.
* I was putting my syringe from the coral snow in a measuring cup every night. These measuring cups I use to hold my water (including RO water) when performing my weekly tests. I think KZ puts some calcium in the coral snow because that's when my Calcium reading shot up. It also shot up on my frag system at the same time. Both systems are not connected so I am not sure how accurate that calcium reading is. Either way, it would not cause the problem and there is no precipitation.
I have a 1-2 inch sand bed and haven't really messed with it because my coral prevents me from syphoning it. I run filter socks and change them weekly.
Here is the strange part. I have great PE and my growth is out of control...
Suggestions?
