Nitrate 6ppm Phos 0ppm What should I do?

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...

For weeks I have been trying to lower my phosphates, and it is unclear to me why I had not been successful. I currently have 0.34 ppm phosphate (Hanna ULR) / Nitrate 10.8 (Hanna). I would like to get to 0.05-0.1, but not much lower than that, since I had previously dinos due to 0/0 parameters...

Hi all, I’m looking to upgrade and add some equipment to my sump. Currently running a TMC Reef-skim 200. Reading some reviews supposedly it’s not that great and there’s better, what would you recommend for my 36G with sump? My main complaint with it is the LOUD buzzing. Tired of years of...

Hi all I am looking for a large media reactor. Looking to specifically use for GFO in a 800 gallon system. Does anybody have any recommendations for large scale reactors? TIA

Hello reefers, I’ve got some crazy high phosphates, 0.25 to be exact. it was probably from LFS water, I already ordered my own rodi waiting for it to arrive , but I need urgent help with Fauna Marin PowerPhos GFO since honestly their instructions suck. This is the product: my questions are...

I have been battling hair algae for a couple months now. Basically, target vacuuming up from the rock work, but it is getting out of hand due to high phosphate levels. so, I started running GFO in a reactor, but now I have cloudy water. Is this normal?Does this eventually run clear?

Carbon and GFO like new

Initially I had a nitrate/phosphate issue where nitrates were at 30 and phosphates were at 1.5. changed feeding (including feeder, food types) and nopox and got the nitrates down to 10-12. Fine with with that. Phosphate still was hanging at 1.1 and just not coming down. Added HC GFO to a media...

So about a year ago all my coral got nuked due to some heavy metal contamination and I switched to FOWLR but i wanted to give it another try and I'm trying to get my parameters in coral range but im having PO4 issues. For the past month or so they have been consistently 2.0ppm which is obviously...

Is it possible to dose phosphate during the optimal period of the daily photo cycle, based on the best time corals are known to absorb phosphate from the water? Then to keep it from climbing, and reduce the time spent monitoring, remove the phosphate daily, with a GFO reactor on a timer, running...

Brs carbon reactor. Comes with 2 mostly full containers of carbon.

Please share here your preferred method, when it comes to using GFO (Granular Ferric Oxide) . Do you run 24/7, intermittently or never? Leave some details about your system (age of your reef, size of your tank, type of coral, what reactor you run, what you feed, substrate or none) and reason for...

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...

Good evening fellow reefer. I could not seem to find a answer to my question so I hope I’m in the right spot. I have ordered a BRS reactor combo with bio pellets & pump. Is it possible to add a second small reactor for Carbon and GFO and run off same pump in parallel with the Carbon/GFO being...

I’m part of a Brazillian group of reefers that get together every week to discuss online reefing topics (Amigos do Marinho, YT Chanel ForipaReef). I would like to share with you an interview we made with @Fauna Marin CEO, mr Claude Schumacher, where we discuss with him many interesting topics...

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...

I am currently half way through my fluconazole treatment for bryopsis. My phosphates have jumped substantially, but I can’t do a water change yet since there is still some bryopsis that has to die off yet. Does anyone know, during this temporary period, is there any downside to doubling the...

I've been struggling with high phosphates and currently have a refugium to help reduce my nutrients in general. I recently added BRS GFO to combat the phosphates. Is using it in the media bag fine? Or would it be better to use it in a reactor? If for a reactor, what would be a good reactor for a...

Looking mainly for Aquamaxx reactor but open to others.

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...

Not much used. Actual weight after use is 5lbs and 16oz. Asking $120 with free shipping.

Turns out I won't be needing GFO on this tank, so I'm selling an almost full 4lb container of BRS bulk GFO (3lbs, 11 ounces). Asking $40 locally, or $55 shipped* * I'm 90% confident the original container will fit in the medium flat rate box, but if it doesn't, I'll have to repackage in a...

So I just upgraded to a JBJ 65, and in the market for a media reactor to run GFO. I currently have an IM Minimax Desktop reactor, and find that it's a bit loud and ineffective. What are some low profile/quiet reactors that wouldn't need to be run in a sump? I've been looking at the Aquamaxx...
