    RODI unit recommendations

    My RODI unit isn't filtering well. I've had this problem with it before, and had sent it back to the manufacturer, who reseated the membrane.... that was in August, and it's doing it again. So I want a different unit. Anyone have recommendations for a reliable, low-maintenance unit? Links...

    seeking beneficial macro algaes

    So, I'm considering ordering from reefcleaners.org... I need more snails anyway, and it could be fun to grow some macro in my sump instead of other stuff. I'd like some species of macro that won't take over everything, but are pleasing to look at. It would be neat if a few of them could be fed...

    New "canopy"

    I keep fish that jump (wrasse, anthias, jawfish, etc) and have struggled with finding a lid that will keep stuff in while having a minimal impact on stuff like temperature, gas exchange, and loss of light. I was stuck using the glass canopy built for my tank, which required frequent cleaning...

    new salt mix is weird...

    So, I ran out of my favorite old salt-- which was running low on alk pretty consistently anyway-- and I'm on an epic journey to find *the* perfectly balanced salt mix. I'm mostly looking at the balance of mag/ca/alk. Today, I made up some instant ocean reef crystals because my mom had a bucket...

    brain corals v. fish....

    situation #1: So, I have a large wellsophylla open brain, which I had to give to my mother because it stayed shriveled up for too long. In her tank, it opened up and did very well. Now, it's back in my tank and all shriveled again.... and I see my sailfin periodically pick at it, as if looking...

    I have this fixture in the 72" version: Metal Halide Lighting: Marineland Marine Series Pro Lighting at Foster & Smith Aquatics the bulbs appear to be going out already. They've only been running since December. 4 of the 8 t5 bulbs are doing that weird wavy thing that fluorescents do when...

    coral eater?

    Is there some sort of hitch hiker that eats mushrooms and duncans? They're disappearing from my mom's tank, and I have no idea what to look for. Any ideas welcome.

    duncans and monti not happy...

    So, my duncans are dying off one by one. In a similar (though higher up) area of my tank, a monti digitata is bleaching from the bottom up. The only thing I've changed in the past several months is the addition of a K4 at the opposite end of the tank, which I did about a week ago for cyano...

    tunicate.... maybe?

    So, my Mom's torch coral has got a weird growth at a juncture between two branches of the torch. It first appeared white, as shown in the photo. Now it's got little black dots along the ridged part, and the opening is striped white and red. Anyone know what this is? It doesn't seem to...

    Adding to my CUC

    So, I need more CUC. All my hair algae has been eaten by my sailfin.... but I've still got some cyano, and maybe diatoms. Hard to tell. Mostly it's in my sand bed, but I also still have quite a lot of regular (green) algae growing on glass and rocks. So, here's what I'm considering getting to...

    non-skimming skimmer

    I have an ETSS Evolution 750 (this).... it was skimming very well for months, then I had problems with flow getting to my sump. When I fixed the sump several weeks ago, I also took apart the skimmer and cleaned off the goop. I rinsed with tap water, then dried the pieces with paper towels. Since...

    canister filter for polishing/carbon

    I want to start running carbon and polishing my water after my water changes. So I got a fluval 205, and some of their "polishing pads" which is basically just cotton, I think. Anyway, I set the thing up as instructed, but it keeps spewing micro bubbles around. what have I done wrong? I only...

    ATO system

    So, my previous cheap ato system (float valve and a back pressure thingie that connected to the RODI unit) failed catastrophically several weeks ago. I'd like to find something more fail-proof so I don't have to worry about problems when I'm away at a conference this summer. What do you all...
