LPS corals receding

"If you had more it rate in your tank you'd probably be able to keep PO4 down without the PhosDown."
- more what?

"What do you have for clean up crew? What type of lights and what is the light schedule?"
- CUC: couple of trochus snails, there should be some nassarius in there, and 4-5 zebra hermits
- lights: 3 x kessil 360, running from 2pm to 9pm
- supplement with 2 x t5 (coral plus & blue plus) from 4pm-8pm

"When you do a waterchange do you clean off the rocks with a baster and vacuum the sand or do you just take water ot and out water back in?"
-vacuum gravel yes, basting rocks, not so much

Maybe something in the water, I would make the switch to ro/di if possible.

If you had more NO3 you're PO4 will come down.

Myka's advice was meant as "Po4 at 0.04 ppm is great. NO3 at 0.00 ppm is not good." She typo'd.

You're bacteria is NO3 limited right now. Get your NO3 up and PO4 will come down. Carbon dosing helps.

Also, blow off your rocks before you do a water change every time.

Look up redfields ratio, but based off your parameters i dont think that is your issue..

It would be unusual for for cal and alk to "stay steady" without dosing and and doing water changes every 4 weeks... but if your levels are acurrate and stay steady i would think it may be some contaminant..

Are you filling 12 canadian springs bottles to do water changes?

How do you get your water?

They deliver once a month, but for my weekly top offs I pick up from this place in steveston or a crappy tire. I eventually plan to switch over to the steveston shop for my monthly water changes also.

gotcha. I picked up a bottle of NO3PO4 so will start dosing that this week. thanks

Personally I'd stop dosing foz down or any other chemical that you're using that isn't just the basic alk, cal and mg. I find if I use any "reef safe" treatment for anything I'm gonna loose a coral or two.

Are your Scoly's under direct light? maybe shade them a bit.

I'd suggest a big water change or two but I know thats hard with your volume of water especially if you aren't making RODI at home. Still when things go buggy I like a couple of big water changes to remove anything that may be in your water.


Are all your other coral totally fine? What else do you have? Do you have a lot of coral and its just a couple that are going bad but everything else is fine?

I just did a 90g water change last month due to a cyano outbreak. I have scheduled a WC this week as the cyano is back and I am about to put in chemiclean.

As for my other corals, zoas, doughnuts, and acans are fine, as are some of my scolies.

as for adding stuff, I am going to stop dosing zeobak and fozdown going forward, and try this carbon dosing that some others have suggested. although I still plan on using prodibio bio digest every 2 weeks.
