So, I’m having a big problem with yellow water. It’s not slightly yellow, it’s noticeably yellow. It’s an ~800L system with some messy eaters, but nitrates are 0 and phosphates are ~.05, probably due to lots of decent size clams) if that’s relevant. Organics must be low/consumed by something else, because I can go a week and barely get algae on the glass, but I feed heavily and everything (fish, clams, anemones, a few corals) are growing quickly.
I’m using quite a large amount of carbon (about half a liter by volume of Seachem’s Matrix carbon, replaced every week) that the entirety of the system flows directly through several times per hour. I’m also using 120mg/hour of ozone in a compression reactor. There’s no skimmer on the system. Water changes are twice a month of about 1/4the volume of the tank. I’ve even tried low dose H202 dosing (50mL 3x/day) for additional oxidation.
And…no luck. The water looks awful.
I’ve tested to make sure it’s not particulates of some kind using calcium carbonate and 5 micron socks. The amount of carbon also seems to have no impact, I tried a very large amount, small amounts, nothing seems to help.
I’m awaiting a new ozone generator when I’ll bump the ozone up to about 400mg/hour+ to see if that helps, but I’m not sure that it will.
I’m at a loss! Any suggestions? More ozone? Use a skimmer? I don’t usually use a skimmer because I don’t want them removing all the food I add, and other systems I have that are skimmer-less don’t have yellow water…thoughts are appreciated!
