I almost hesitate to say anything, but I seem
to have gotten rid of this stuff. I've been fighting it for six weeks now, 50% WC's every other day, tinkering with nutrient dosings, CO2
, everything it seems like. The other day, I'd finally had ENOUGH
, as I'd do water changes, siphoning out the stuff, cleaning plants and literally within two HOURS
it'd be coming back.
Soooo .... I started up the python, siphoned and cleaned down to my 50% mark, reversed the flow, filled it up ... then did it again. And again. About 4 times basically doing a 100% WC. I did NOT put in the de-chlor while I was doing this. In my limited experience the fish (I don't have any inverts except for pond snails) can stand it for a while without the de-chlor. I did not put any baking soda in. Somewhere in there I decided not to clean the filter, although I did stop and start it a couple of times to help knock loose any crud in the tubing. Then I went ahead and did a normal dosing, added de-chlor (Amquel) after the last cycle, and ran the Vortex, cleaning and re-charging it once. It ran for a about 4 hours total. I also changed out a bulb that was apparently going bad (even though they're not that old, about 4 months,) and re-arranged the wiring on the lighting so I could halve the light if I wanted to try that. Cranked up the CO2
a bit more. Also, just for the halibut (getting desperate) added 1/4 cup H2
All this was last Wednesday (I've had company the last few days) and I haven't seen the grey slime since. I'm keeping my fingers crossed. I've been dosing macros, but skipped the traces the last few days. I'm going to start back with the traces this week.
The first day it was apparent that I'd at least knocked h*ll out of it, and the next day I didn't see anything that looked quite like it, although I did peer suspiciously at something I now believe to be a bit of hair algae. I realize this was a shotgun method, and I don't know which of the above things I did got rid of it (hopefully for a long time) but at this point I really don't care which!
