gfo

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...

New to reefing—I bought used reef tank with livestock. I’ve had if for about 3 weeks and have a question on this brown algae. When we moved the tank it had a phos spike to 0.4, and started getting brown algae. I got a phos reactor with GFO running and have since brought the levels down from...

This is obviously my opinion but works great for me and I would recommend this setup to anyone. I’m using a Fluval 50 but I feel like this can work in any HOB filter. The media need is: • Cheato •Filter floss •Poly filter pad •GFO/ chemi pure blue nano •LOTS of bio blocks/pellets/spheres This...

Hi folks, So I have been dosing Lanthanum from ATM agent green. At first I was dosing 2 mls per day, now I am up to 12 mls per day, to maintain phosophates where I want them. I think it is throwing my alk out of whack too. Has anyone else experienced this and what did you do to rectify the...

Alright, where to to begin. I have had a 80 gallon with a 30 gallon sump tank running for almost a year and a half after a restart. I got dry rock and dry sand, which is a mistake on my part, and I am on a fun roller coaster right now. Around 5 months into my restart things were going okay...

How to Control Phosphate Using Hanna Phosphate Checkers and GFO Media PLUS: New gear from GHL, Eheim, Coral Essentials, and Brightwell Aquatics!

Do you put this stuff in a media reactor like you do with bio pellets? Or just in bag? Thanks

My phosphate level (with Hanna UL checker is running in the 0.1 level. I would like to drop it to below this as recommended. I have been feeding less in general (mysis in the PM and pellets in the AM) and have about 8 fish, none bigger than about 2 inches in a 100 gallon with about 20 gal...

I don't know about you but i am tired of cutting filter pads for AIO media baskets. I recently purchased the Purity Pack from Innovative Marine and i love it! Re-usable, Re-washable and to be honest last longer and picks up more particles from the water. Let's hear your experiences and share how...

How long can GFO run before it is depleted? One month? two months? forever as long as the phosphates do not rise? When do I know when the GFO is depleted? Can one Run GFO to long besides stripping the phosphates out of the system? How much do you run in your system? It would be great to...

For a Low nutrient system, should we use media reactor like GFO, Biopellet? I just want to collect everyone opinion.

I've read online that you should never run gfo with Sps corals in your system. Apparently corals will lose colors. How true is this? I currently run a refugium, carbon dose vinegar, and run phosguard but it gets exhausted very quickly. I feed my corals reef roids every other day. Looking for...
