    Lol Murph. It's so much more fun ignoring the easy and focusing on the exotic. One thing I have not considered is the kill-it-with-kindness syndrome. Auggie likes to overfeed the dogs and birds with treats. I should set up a fish cam to see if she's been cheating with the blender fish food.

    Something odd today. I was using a turkey blaster to see what I could kick up from the surface of the rocks to see if detritus might be the issue. Once a week I clamp my largest net downstream from the Gyre and use the baster to kick up debris. The net does a pretty good job.
    I had only treated half of the rock for GHA, but there's not a trace of GHA today, a couple weeks later. Is the peroxide still leeching from the rock? Unlikely if Levi's correct about rapid breakdown. Is it linked to removing the algae scrubber? No idea. Is it linked to turning off the white LED circuit and covering the four single red LEDs, leaving only blues and violets? Possibly. Maybe the baster is affecting the free nutrient levels? It's tempting to change the lighting back to its original spectrum, and maybe even put the scrubber back in. Or...leave it alone, count my blessings and hope I don't see it return.

    Lanthanum chloride. I'd have to order it, but may have to have the post office hold it for pickup. It was about -20 yesterday, and I don't think it would do well in the mailbox for more than a few minutes.

    Any unintended side effects?

    Just don't overdose

    I go 1 cap every week, sometimes 2x a week. Dump into a 2-3 day old filter sock or near the skimmer.

    Why the older sock or skimmer?

    older sock has detritus in it making openings smaller. Skimmer would pull some of it, mixing it with current water, without it precipitating in the tank. Don't put it in the DT, always in the sump.

    I do the same thing waiting for the sock get a little clogged. I've read tangs can have a problem if you just dose into the tank as the particles can get in their gills. I've noticed no ill effects dosing into the sock. I've also dosed into the skimmer and then turned it up a little to push wetter skim out, which takes the particles too. If there is a hot tub dealer near you, they might have some in stock. I use sea klear phosphate remover. Don't know about other names brands.

    Next time you do a water change fill a 5 gal bucket 3/4 of the way.

That's only the detritus on the outside -- if you could get to the pores you'd be even more amazed. If the rock has GHA on it, you'll see three times as much as the detritus collects in the algae making it's own detritus trap.

    I had current in my tank such that I had difficulty keeping even medium grain sand/rock in place. Yet when I pulled my rock out of the the tank and sprayed it off with a high-pressure nozzle TONS of detritus came off even on rocks that were up near the top.

    I've never been a believer in vacuuming the sadbed as I have so much life in it but sometimes I wonder as there's so much detritus in it.

    I don't doubt it. I kick up plenty of debris just using the turkey baster

    And you wonder why I went bare bottom. I can see the detritus as it starts to build up. Rock breaks down too, so that is some of what we are seeing.

    I've wondered how much of what I blast out of the rock with a turkey baster is detritus and if any of it is beneficial bacteria I'm blasting the heck out of. Any thoughts?

    bacteria lives in the rock. Anything you are blowing off the rock is sand and detritus build up.

    Still no sign of GHA. Very strange. Other than dipping half of the rock in dilute peroxide, the only changes I've made to the tank were to get rid of the scrubber and kill the whites and the 4 red LEDs. I may turn on the whites and check the spectrum with the spectrometer for any red emissions. I know that should have only been a temp fix on the part of the peroxide.

    Still no GHA except what I found on top of the overflow that I never removed. My nitrates are creeping up again, but I figure it's because I didn't dose while we were in Maui for a week (Awesome footage of whales jumping right in front of our room!). Even so, I shouldn't have to dose if my DSB is working, which has been set up for nearly a year. I decided to swap out the Petco sand in the DSB. It's definitely calcium chloride sand, but it's not porous like aragonite. I had some old coarse aragonite sand set aside for future use and put that in the DSB section of the sump. It took 6 weeks last time I had a working DSB, so we'll see how this goes.

    In the mean time, a 4-head Jebao dosing pump is coming from Amazon (under $70) that I'll use for most non-tank-crashing things. I also ordered several dosing pump heads and power supplies that I'll play with (along with a timer) for alk.
