How to dose Phosphate Rx in your reef tank
Reef tank 7 years ago 16,947 views
I've been using Phosphate Rx for a decade, and it's my preferred product to keep PO4 levels under control. No GFO for me. I've mentioned it many times, but decided "I guess I need to do a video about this product after all." I do realize I could have explained the process in about sixty seconds because it's that simple, but I wanted this to be a fun video. Hope you liked the flashback. I want to thank A.J. for helping film this one. :) Purchase Phosphate Rx here: http://www.melevsreef.com/product/phosphate-rx Purchase 4" 10 micron filter socks here: http://www.melevsreef.com/product/filter-sock-10-microns Facebook: http://www.facebook.com/melevsreef My websites: http://www.melevsreef.com http://www.reefaddicts.com Music by: Amazing Cinematic Trailer Music / No Copyright Free Music https://www.youtube.com/channel/UCHEioEoqyFPsOiW8CepDaYg
No3PoX is a different product, which I know helps with nitrate and should help with phosphate as well.

knock it down from 0,25 to 0,04 in 24 h with no issues , sps,lps etc in tank
1. Has anyone else tried this with seahorses? I'm not too worried but since not a lot of people keep seahorses, I'm wondering if there is any anecdotal evidence on this.
2. Should my keep my phosguard in my reactor running while/after I dose?
2) Should be fine. I don't remove anything when I dose with Phosphate Rx. You may need to rinse off the mesh bag after dosing, if it seems coated afterwards.
I do and tested. Phosphate shows 0 and phosphorus shows .085.
Not sure what the exact science is.
If I have a 110-gallon tank, and my stuff is at 0.09ppm, how should I use this product? How many drops? How long have you added it?
I have, NPX biopellets, and ATS with five weeks operating, my reposition of water is the osmosis system
thanks :)
If your tank has silicates, you'll want something that removes them. I've not used Phosguard personally, but it lasts a long time. I don't know if one week would have any notable effect.
You may have something else on the sand, not diatoms. Are you posting on reef2reef yet? I'm on there as melev.
Thanks,
Josh

And quit killing those LPS; they are my favorite coral. :)
Thanks for any assistance you can provide.
(Very informative video.)

The rectangular filter sock has an inner dimension of 3.75" and outter dimension of 4.5" at the narrowest portion of the rectangular filter sock. Do you that the 4" 10m filter sock would sit on top of the rectangular filter sock okay?
Thanks again for your advice and replies.

(A little bit going in would be better than none though.)
I live in El Segundo, CA (near the beach of the Los Angeles area; south side of LAX airport.)
Thanks again !
(I see you have the 4" 10m on your site. I probably would need a smaller one.)

Don't know if a 10m sock would fit inside of it. would have to be very, very small. Where did you get the 10m sock from?
(Thanks again for your replies!!)

I have an Eshopps sump and unfortunately it takes rectangular filter socks. I had 100 micron mesh filter sock custom made for it (unfortunately, the only way I could get them custom made was if I ordered 30 of them.)
I have a video about Green Hair Algae that mentions Phosphate Rx specifically: https://www.youtube.com/watch?v=xilqKzoOgBE&t=1s You may want to watch that one as well.
But you have to get a phosphate test kit: http://www.melevsreef.com/node/1934 Once you know the PO4 level in your tank, you'll know how much Phosphate Rx to use.

You could use something smaller than a bucket if you liked.
The bucket will have to be higher than the tank. Cut a hole in the lid for the sock to fit in. Drill a hole near the bottom of the bucket for the bulkhead. Put a powerhead in the tank, running tubing from the powerhead into the sock. Secure that hose so it doesn't flop out with a ziptie. Run tubing from the bulkhead back to the tank. When you turn on the powerhead, tank water will flow up and out of the tank into the filter sock, and the water will flow out the pores of the sock into the bucket. The bulkhead near the bottom will drain that water back into the tank.
You may want to drill a few large holes (3/4" or so) in the lid in case the sock clogs up completely so the water goes into the bucket and not all over the place. :)
I don't know why you'd need to dose this at all. It's a single session, takes about a minute to drip it in and then you're done. Plus do you want this type of product tethered to your tank knowing the doser could potentially go nuts and add it all?
I use it on my AIO biocube 14s and have no issues. I just use a fresh piece of "Poly-Filter" and discard after 24 hours.
Great video! :-)
Thanks
Assuming 1ml is 20 drops, 180 dosed drops is 9ml.
(assuming it's LaCl3)
9ml LaCl3 (aq) reduced 1845kg (450gallons) of seawater from 1ppm to 0.25ppm
Therefore, 0.75ppm were removed: 1.38g of PO4 were precipitated, meaning 0.0146moles.
La reacts with PO4 in a ratio of 1:1. 9ml of phosphate Rx most probably contained 0.0146moles of La (aq).
The concentration of the LaCl3 is therefore 1.62molar. LaCl3 saturates at 25 degrees at 3.96M, so knock yourself out xD At higher concentration, there's more room for error though
(sorry for any mistakes, it's been 4 years since high school chemistry xD)
Great video :)
I purchased phosphate RX after your recommendation for it when you dosed it to a smaller frag tank to clear up gha. I used it on a jbj 30gal aio tank with no problems at all. Take Marc's advice, THIS STUFF JUST WORKS!
