So here goes! Been struggling lately with my tank. I am the best green cyno farmer around. (Have the red stuff too!) If you need some let me know!
So here's what I think went wrong. I used a few pieces of live rock from my first tank with a large healthy population of amphipods. To the point that every inch of surface in my tank was crawling with them. Some nearly half in inch long, so big that when I fed frozen mysis they would swim out and capture an entire piece. I bought a few frags and they were getting harassed by the amphipods so I decided to buy a wrasse to deal with the ugly critters. He dealt with the population like a pro and after a few days they were no longer visible during the day. Unfortunately it appears the amphipods were also keeping the cyno at bay and soon after the green slime appeared and spread.
I'm also thinking not enough nutrients. My nitrates are undetectable (salifert and other test kits) and phosphates as well. Besides the amphipods I think I was overskimming. I'm trying to feed a little heavier, but I don't want to overcompensate, so I'm going slowly and trying to blow off the cyno when I don't have to chip ice outside. I also turned the skimmer down a little, but I want to be careful as I'm also dealing with a slowly declining PH.
Params usually read:
Sg: 1.026
Temp: ~79
Ca: ~445
dKH: ~8.7
Mag: ~1360
PH: 8.0-8.1
NO3: Undetectable
I also had a hard lesson in aquarium keeping in wisconsin. I used to live in florida so ordering from the winter sales wasn't too much of an issue for shipping. I tried that here.. they got stuck in shipping and the corals arrived in brown clouds of 50 F water. Glad I at least got store credit. I think I'll wait till april.
I have also been working on an aquarium controller. Right now it's more of an aquarium monitor. I hooked up a rasberry pi to the atlas-scientific ph and temp monitors. Wrote a python script to output params to an influx db I have hosted out in the cloud. I have grafana pulling the stats, and have alerts set up so if the temp goes out of range, or if no temp is being reported (power outage) I get a phone call.
So please someone post some nice pictures!
