    So the question isn't necessarily if aluminum is present, but if it is actually toxic, and if so, how much is a toxic level. It seems like everyone who claims to have had issue with it has had it effect primarily soft corals.

    Whoa, these are the big bricks? How long have they been wet? It can take a few months, but I bet your nitrate levels drop significantly...

    I was thinking the same thing when I heard several people that had bought 4 or 5 of them. I have one in my 125 gallon and can seem to find any no3.

    Mines been in my tank for 1.5 years and it's been good. No coral deaths that I can tell related to it.

    I thought those bricks did nothing for No3, only nitrates and ammonia... hell I think BRS did a video on those too.

    In my experience they reduce nitrates very effectively.

    They work good for nitrates

    The 4" bricks do nitrates.

    NO3 is nitrate.

    Nice catch. But I was assuming he meant nitrite?

    Only the big blocks. They have very little water movement in the center which promotes anaerobic bacteria that help with nitrates

    Yup, looking at the time on that, it was me after a long day of summer school classes (I mean crap almost like a real job being at work from 2 to 8pm! ) and I was tired... I meant No3 = Nitrate, and the blocks only did nitrite and ammonia.

    So the big blocks you don't want to use as "walls" to force the water through the center, you want them to just sit on the bottom of the sump?

    That was my understanding. They sit in low flow area.

    I read about the possibility, but it doesn't worry me. I mean, I don't know the effect on animals from aluminum, but it is at least not an alarm bell like leaching copper or something.
    Plus I think nitrates are worse for some reason. And I have no idea if it is working to fight nitrates or not.

    When are you gonna recheck nitrates?

    I have mine at the bottom of my fuge. So, fairly low flow for reasons stated above.

    Will recheck next week. I've added biopellet reactor, which I regret supremely due to the damned pellets clogging up everything and that stupid incident involving the filter sock which flooded my dining room. The wood floors are F'ed.

    I will likely remove the reactor once the stupid pellets are done.

    I know what you mean about hardwood floors. We refinished ours about 2-3y ago and I've had a couple of floods....so, the boards are cupped.
