Need help with a two issues
My tank is
-t5 lights (on 3-11)
-CO2 (on 2-10* ... I checked to confirm my set up, and noticed some extra buttons pushed on the timer, gas was running 2-12)
-EI using flourish as my micro, KN02 + KH2PO4 for macro
-weekly 50% water changes.
Two issues are
1) death of angel fish
The gas & ferts started in Sept. Long before the gas, I had an ancient angel fish that wasn't doing well, and it died late Sept or early Oct. I added 2 new ones to keep the 1 remaining angel happy. One of the new angels mysteriously disappeared, another died suddenly near the end of Oct. There was no sign of distress whatsoever. It ate fine the day before. It was active in the tank. Then one morning the fish was dead. Now my remaining angel also died, and it was somewhat sudden as well. I did notice it lethargic, maybe even gasping near the surface (something I did not see in the others). That behaviour only lasted a day, and the next morning it too was gone. What's even stranger is that I did a water change the day I noticed it gasping (the gasping was happening before the water change and continued after).
Before I add any new angels, I'd like to figure out what's going on.
My primary suspect is that the gas is the culprit, but no other fish seems bothered by it, and I only saw gasping in 1 of 3 angels. But maybe I should add a drop checker just to be sure?
Or could the EI be hard on angels? Maybe I'm not dosing correctly?
I am taking a water sample to my LFS to see what they say.
2) Algae. I'm attaching two pictures, of the worst spots. The picture of the sword leaf is the worst leaf on the plant, but most of the sword looks better than ever with no sign of algae. I could trim that leaf and the problem is gone, but that's only a temporary solution. I'd rather correct whatever is causing the algae.
The java fern is near the surface, and close to the spray bar from the filter. Is it unhappy with its location? This is the worst algae in the tank. There's little on the glass, and little on the other plants. But something is obviously wrong here.
With both plants, is the problem too much light, is something wrong with the ferts (too much, not enough) or is there not enough CO2?
Where do I begin?!
Thanks for your help.
mods, can you please remove the "a" from the title?
