    Erratic Phosphate Levels

    Hey everyone, I'm experiencing some difficulty I was hoping you could shed some light on. I'm trying very hard, and open and flexible to any suggestions. I'm experiencing erratic and varying phosphate levels. I cannot seem to maintain consistent levels ~ 0.01-0.05. Instead, I either bottom out...

    Leaching phosphate from rock

    Hi all, my tank is 3 months old and I have made the decision to cycle some Caribsea life rock away from my main display which is eventually going to replace existing rock in my tank, as I believe my crazy high phosphate levels of 0.21ppm are being caused by leaching phosphate from the rock that...

    5 or 10 micron filter sock for lanthanum?

    Do 10 micron filter socks filter lanthanum chloride precipitate well? Or does a 5 micron filter sock actually do a noticeably better job? Anyone has experience with both? Is the 5 micron sock harder to clean? (talking in terms of dislodging the precipitate for future use with lanthanum...

    Massive GHA problem + cannot get phosphates to drop

    I'm currently battling a GHA problem on my 45 AIO cube and am just completely at a loss. Willing to hear any and all advice and would prefer not to use Vibrant since I've read horror stories.

    Phosphates are very high

    Hello, I have a 100 gallon DT with a 34-gallon sump. Probably 100 gallons total. I run a skimmer, and carbon in a reactor. I have previously run GFO mixed with the carbon but eventually moved to auto-dosing NoPOx. For a while everything was good. 0.1 phosphate, 1 nitrate. Over the last few...

    Help with Nitrates and Green Hair Algae

    Hi, I'm battling green hair algae in my 14g tank. I started by getting phosphate levels under control and trying to maintaining levels of <0.1. Levels creep every few days, though. It's helping but not completely. According to my Red Sea test kit, the nitrates are undetectable, which seems...

    Phosphate question

    I have a newer tank setup. 20g AIO cube. That being said, I turned my middle chamber into a chaeto reactor and it doubled in size in about two weeks. I just tested my levels and came up with this - Ammonia .25 Nitrate 0 Ph 8 Phosphate .25 Nitrite 0 Full disclosure I’m not 100% since I’m using...

    Alkalinity and Lanthanum Simultaneous Dosing/Offset Dosing

    Good afternoon. Question: Is there a rough ratio I can use to dose alkalinity at the same time as I dose Lanthanum? Why? I have an Apex with BRS dosers and intend to inject LC into the skimmer as needed to control Phosphates. I've experimented with it and it seems to work. But yes...the...
