phosphates

I have had a FOWLR tank for a few years… I recently just started adding corals. Only 3 so far. I was dealing with high phos so I added chemi pure elite and that took it down to 0.10 and I stopped using it. A couple of days ago I rescaped my tank. Broke down the live rock and just changed how...

Hi all. Long story short... I bought some cruddy USED LR years ago, jet washed and scrubbed all the algae and mess off of it, soaked it in RO and then setup a tank. Never had the best results and then when I moved house I let it dry out thinking it would kill all the nitrates and phosphates with...

I’m an intermediate reefer and I have my main display which is a 100 gallon tank sps dominant mixed reef and that tank blooms with healthy corals and full of fish and I have been successful in controlling nutrients and chemistry. Anyways I have a 13.5 gallon tank (fluval evo) I’ve been running...

Is Kalkwasser a tool available to use to lower phosphate levels? Further, do all 2 part Alk & Calc additives bind with, thus lowering, phosphates? After watching a Tidal Gardens video that mentioned using Kalkwasser as a way to lower phosphates, I came across some information and some older...

Hi all, I tested my water Friday, did a water change and tested again today (Sunday.) My phosphates rose from .8 to 1.6 over that time span. The only thing I did between the tests is add a small amount of phytoplankton and feed slightly heavier. My Phosphates have always stayed at .6-.8 which...

I'm looking to get either a roller filter, or an algae turf scrubber to help control phosphates and nitrates (don't want refugium, use GFO/Rowaphos, a bio pellet reactor, or NOPOX). Who has a favorite that won't bottom out nutrients?

Hello reefing community, My parameters are: Nitrates 8.5 Phosphates .01/.02 Alk 8 Mg 1450 Calcium 440 I have some few hair algae. My corals look like if they are starving. My question is. Should i get my phosphates higher?

We have a very nice Elegance which has been a picture of health until about a week ago (don’t have a pic of the change). It had been moved due to our Bella Goby digging it out and needing to return the sand into place to put it about where it had been prior. It has always tolerated sand being...

Hey folks, So I recently discovered my phosphates were slowly rising (5ppm peak) after a few of my corals looked sad, and snails seemed to have given up on life. I wasn’t able to reduce them enough through export or less feeding, so I resorted to dosing 5ml of NOPOX per day which is doing the...

Struggling to pin down my phosphates… Tank is approaching 1 year old. Had mature media from a previous tank. For the past month I’m struggling to keep my phosphates stable. Started off with chaeto in a light reactor. Nutrients were low and stable. Found phosphates slowly rising a couple months...

My tank is 350 litre and about a year old. I’ve never had problems with phosphates in the past, but as of recently in the last month they just won’t seem to go down. I bought a TDS meter for my RODI and it’s at 0, and even then I switched them all out to be sure. I’m dosing rowa in a reactor and...

Hi! Now I continue to study marine aquarium and there is some misunderstanding, how many nitrates and phosphates should I have? I want to contain a mixed reef: simple SPS, LPS, zoanthuses and discoactinias. Some say that it is necessary to keep NO3 and PO4 at 5 and 0.1, respectively, but others...

I've read that these phosphate reducers can impact your fish and corals so I want to be very cautious about dosing. I've doing some reading. So right now, my phosphates are around 0.37 ppm. My goal, at least for now, is to get it to 0.1 ppm. Based on the following website...

Good afternoon, I have a 22 gal long tank, with a toadstool, singularia, kenya tree, frogspawn, derasa clam, and a pulsing xenia. The tank is 11 months old. My biggest worry is my Sinularia coral. I recently went on a 3 week long TDY to florida, and had my mom take care of my tank while I was...

I think I just nuked my 21g nano tank. I was working on my phosphate dosing tube that had an air pockets problem. I let it it run for quite a while but there wasn’t happening much, thought there was a blockage somewhere in the tube. .. until I figured I was checking the wrong dosing tube. I...

Recently got a new 15 gallon tank and just tested after adding zoas and a gsp frag. Noticed they weren’t doing well compared to my 13.5 tank. These are the results. Need help in trying to figure out a solution. Doing a water change now hoping it’ll help. Tank has a filter sock and filter floss...

Hello again! Sorry for such a basic and dumb question.. I'm just at a complete loss. I swear I thought I've done everything right, yet I just don't know why my Ammonia won't drop to 0. Here are my parameters... I've been having issues keeping Alk and Magnesium lower as well. It must be the salt...

Okay, okay. I know all corals consume nutrients, but I have a strange situation. I have a 30 gallon BB cube that is about 40% covered in GSP. There are 4 fish (cow fish, damsel and two percs) in addition to some RBTA and zoas. The Hanna checker reliably tells me this tank is at 0.00 phosphate. I...

Just got my ATI tests back and my phosphates are off the charts high. Oddly enough I have zero nuisance algae to speak of and everything is healthy. I’m a big fan of “if it aint broke dont fix it” but also curious how Im so off the charts here without any signs of it. Salinity 34.41 PSU...

In this thread I will be using the abbreviation C (carbon) N (nitrogen) P (phosphates) The word “Parameters” will refer to no3 and Po4 only At no given point I will be using the above abbreviations to describe parameters as it’s widely seen and confusing wend discussing ratios, Ratios are...

I am in a situation now where even with 25ppm of nitrates in my 20gal Red Sea Max Nano, I still have no detectable phosphates and am curious how. Verified by multiple ICP tests and Hanna Checker. Tank is almost a year old - feed twice daily, 8 fish and 10 coral. Everything healthy. Is there a...

Hello, I need some answers please. I setup a fluval 13.5 evo with live rock live sand and a bottle of dr Tim’s 5 weeks ago but I think I left the live rock in the open air for too long while setting up aqua scape and had some coraline algae die off chipping off and floating. My question is, does...

I've had .3 phosphates for a while now and have been using a GFO reactor in a half stocked 7 year old crashed tank I inherited 4 months ago. I'm looking for other less harsh methods of nutrient export other than GFO. I've heard about refugiums and algae scrubbers and their mixed reviews. But...

So my question is will using this reactor - https://www.tropicalmarinecentre.com/en/tmc/aquarium/equipment/media-reactors/_/reef-filter-nano-50-white-uk-50-litres11-uk-gallons Combined with seachem denitrate work as to create and anerobic chamber to turn nitrates into nitrogen? I will be using...

Hello, So I have a 25g JBJ Biocube. It was doing pretty good until recently. Been having issues with Phosphates and Alkalinity. So I’ve been going to the LFS weekly and having them test everything. Asking what I should do or not do. I went in yesterday expecting my Alk to have dropped and it...
