po4

I began a Fluconazole treatment three weeks ago with it ending this coming Sunday. It’s done wonders for my GHA yet I’m somewhat confused as to why my phosphates are testing 0 this far into the treatment. I removed all chemical filtration media, no UV, kept skimmer off for 3 full days. Just...

So basically i have a new 60-liter nano tank with stable parameters except for a low phosphate level (0ppm) checked with hanna ulr phosphorous checker . The nitrate level is at the desired range (8 ppm). I am considering dosing phosphate additive to reach 0.03-0.05 ppm (nyos phosphate) , but i...

Hi reefers, This post might be a bit lengthy as I want to thoroughly explain my situation. I've been maintaining a 20-gallon reef tank for about a year now, but it's starting to feel cramped. Plus, I love collecting rare and high-end corals, so I've decided to upgrade to a 100-gallon tank. Now...

Hi All, In short, I need to reduce my phosphates. I will being doing water changes now that I've fixed my RODI issue, but I am wondering what the best one time punch phosphate sponge is to speed up this process. Back story for those interested: Had a reefing blunder this past month that I am...

Hey, I found recent AF product - Anti Phosphate - https://aquaforest.eu/freshwater/products/af-anti-phosphate/ It's relatively light color, so it does not seem to be a ferric hydroxide related as most of reef dedicated products are. I wonder - what could be the ingredient and why isn't it...

Can dosing alk drop PO4? Is it appropriate to assume I made the corals happy and they are using the PO4? Both are being measured with Hanna testers that have always matched up with ICP tests. I started dosing Red Sea KH/Alkalinity to bring my system up to proper levels. I was in the 5’s and...

I have a question about NO3 and PO4 chemistry. Usually when PO4 drops NO3 would drop with it right? I've been having problems keeping PO4 up, so far I removed pellet reactor and disconnected the refugium. But as soon as I turn the fuge back on the PO4 drops too fast, is it possible that the...

I see a trend towards people using lanthanum products to control PO4 these days, however I had a bad experience the one time I tried using Phosphate-E, and never could get a refugium dialed in... So I have stuck to old-school GFO in a reactor... What methods are you currently employing to...

Okay everyone I have run into an interesting and difficult predicament that I think I need more information on. So I have two tanks. Let's call them Tank 1 and Tank 2. Both tanks have been running for one year, both tanks have their own filtration systems with exactly the same equipment, and...

Hey folks I've been reefing a long time but i would like to take my tank to the next level so to speak. As the name of this thread suggests, im having an issue keeping my phosphates in check they go up and down and no matter what I try im having an issue keeping them stable im not going for a...

I was watching this video with @Lou Ekus; he says he personally doesn't like seeing people running GFO 24/7. What are the observed (rather than theoretical) drawbacks with the long term use of GFO? Obviously, a sudden drop in PO4 will cause issues, but this is not what we're talking about. What...

I've been battling some cyano and turf algae pretty much since I've been in the hobby 2 1/2 years ago now. About 18 months ago I thought I found the end all solution...that being the Zeovit system. Ever seen then I've been running the full system (Zeo Stones, Carbon, Zeobac, Zeostart, ZeoFood...

I'm dosing a product to assist in sponge growth, which also requires some silicates. Will Phos 0,04 remove silicates? Does the resin have a higher affinity for silicates than for phosphates? Does it have a higher affinity for yellowing compounds, tannins than for PO4 and silicates? Thank you!

Had a bump in PO4 for the past two weeks, been monitoring but not coming down. I auto-water change 10% / 25 gallons a week split over the seven days and have approx. 30 gallons mixed each Sunday for the coming week using RODI and Tropic Marin Pro salt - Have been doing this for a couple of years...

Heyo, ** Questions: - from what I'd read if I were to dose some of the calcium carbonate part of my b ionic solution it - seemed like I could precipitate out some phos into crystals, out of water column, but being that I don't have a skimmer I don't think this would be beneficial to export it...

OK, so I've been battling high NO3 & PO4 for a couple of weeks now. I've read almost every thread with the same issues, but I can't seem to get any subtle changes for the better. I'm at a loss for what to do. I'm not looking for a quick fix, but I'd love to be able to see *some* changes for the...

So, we've been trying to reduce PO4 slowly (started the whole process with 0.8) to get more coloration out of our SPS. We actually have a lot of great growth and no algae in our system, which we've been very happy about. We are currently running ROWAphos and Triton Carbon (2 cups each) in our...

Hello Reefers: My tank is a year old. It is a 125 gallon with 29 gallon sump. I have about 100 pounds of live rock that have been in there since the beginning and a 2 inch sand bed since the beginning. Here are the parameters Temp 78 Salt 35 PPT nitrites 0 Nitrates 0 Ammonia 0 Alk 12...

What an ICP-OES machine CANNOT test As the company that developed the method for sea water analysis and making broadband testing available to aquarists, we at TRITON often get asked what an ICP-OES machine CAN test. These days it is getting more and more confusing with the proliferation of...

Hello! Over the years this has been one of my favorite subjects. A while back I noticed my tanks doing a lot better with more NO3 than PO4. When the NO3 matched the PO4 on the lower side the tank begin to grow hair algae in the sump, and dark brown algae on the rocks, overflow box, sand-bed...

I use an iDip to test my water. I am confused about the reading it is giving forthe PO4 test. One screen shows a reading of 0.16 ppm (as P) and when I scroll over, the diffent measurement is .49 ppm (as PO4). Which unit am I suppose to be looking at? Thank you in advance!

Hi Tim and everyone :) I am in the process of rebuilding my tank and switching to the full Triton method. I see that the recommendation is to switch between AL99 and RowaPhos on a regular basis in order for the Rowa to remove any aluminium that has leached from the AL99. My question is why...

I've been treating Pukani and have given it a bleach treatment, acid bath, and it has been soaking in ROID w. heater for a few weeks. The PO reading started at .12 and had been dropping to .02 until my last reading which came in at .22. I know there is variance in these test kits (hanna) but is...
