No, I carbon dose with vodka, so I think that is causing the cyano. I think I'm going to dose more bacteria to try to outcompete the cyano. Going to try this because I don't want to use chemi clean, even though I have a box of that from before that I can use.
Last I checked, Nitrates were in the 30's and Phosphate were like 0.3. I don't have a problem with low nutrients, it's probably too high. That's why I have increased my carbon dosing, and I think I need more bacteria to offset the increased carbon into tank.
I run skimmer and UV. just vodka. I do dose LC to lower phosphate as well, just very minimally.
I don't want to use chemiclean right away because it'll probably throw off my biome. But may need to resort to chemiclean if I can't do it naturally with bacteria. Someone said to use vinegar instead of vodka, so I haven't tried that yet.
The while Zeovit line is very interesting to me. I recall years ago drooling over their forum and many tried to get that true low nutrient aquarium and crashed thier aquarium I liked thier stuff because it was super concentrated and one could see the results. They were a decent line when distributed through Vertex. I think there are also spot of similar products that others have reversed engineered. Phols extra, sponge power definitely worked for me
KZ does have a very interesting line. I've heard good things about a lot of their products especially zeo products, FW stop, Phols extra, sponge power, etc. They are just a bit pricey.
In addition to the bacteria, I'm going to stir small sections of the sand bed to get the trapped detritus into the water column and hopefully down to the filter sock. I remember talking with Mike (thegrun) before he left the hobby, and he had a weekly routine of stirring up different sections of sand bed to keep it clean. It may be that my sand is just filled with detritus and gunk. And that's fueling my cyano.
Measured my Nitrates (28 ppm) and Phosphates (0.29 ppm) with Hanna checkers. It's a bit higher than I like.
Going to try to bring those down to at least below 20 ppm nitrates and 0.2 ppm phosphates. Still higher than more people would like, but that would be a great first target at this point.
