Having some trouble bringing down my phosphate, ive been running a small bag of rowaphos for about 5months with no hit on the phosphates... what could i do to have more impact on taking it down, of course slowly?
 
I would suggest setting up a small reactor. GFO works best when is is slightly turning.

How long before the GFO is changed?

Havent changed it since it was put in :( what would be a good regiment on that?

Mine has been pretty high at some points, and I would suggest once a week till the phosphates come down.
 
Also i run a 139g tank if that helps with a reactor size? Nyos torque?

Okay :) and i run a 139g tank if that helps with a reactor size? Nyos torque? And if that, how much media do i replenish aswell? Do i run carbon also? Also once a week testing on phosphates?
 
I have an 80 gallon water volume and I run 2 cups of GFO until the phosphates come down then a cup to keep the phosphates maintained

I would suggest and simple reactor setup link . I took the pump that comes with the setup off line and install a submersible dc pump that is much quieter and I can regulate
 
Do i run carbon also?
You would not need to run carbon

And if that, how much media do i replenish
I would suggest starting with 2.5 cup and see where you phosphates are at in a week.

Also once a week testing on phosphates?
Test before you start running the GFO and 3 days after you start to see were you are at. Then you can decrease or increases the GFO if needed. It is best to reduce slowly at about half on the first run. It will take a couple week, but slow is good with a reef tank.
 
Granular or high capacity gfo?
I use the granular. I use a product called Aquaforest phosphate minus and have found that this GFO works really well with my system.

When you start, please check back with me. We can make adjustments to your dosing if need be.

I will, thank you :) and just making sure... i start with 2 cups of granular gfo and move up from there if need be or will 2 cups be enough?


Edit: nevermind saw earlier post :)

Could adding more coral help alleviate phosphate?
 
I would suggest using lanthanum chloride (sold as Phosphate RX or Brightwell Phosphat-e) to lower the phosphate level to where you want it first. It’s much cheaper than GFO, especially with a larger tank.

I believe it varies by product. For example, the Brightwell Phosphat-E directions say that each mL eliminates 1 ppm phosphate in 4 US-gallons of water. So (assuming I did my math correctly) to bring a 140-gallon system down to 0.03 ppm would take about 7.7 mL of the product.

I have a formula for lanthanum chloride and use lanthanum from time to time and have found that the phosphate RX is a great product and is safe to use. The direction are on the side of the bottle I think it is one drop per 10 liters

I would still suggest set up a reactor

How much would it be to bring it down to .07ppm? And i assume i need to dilute it aswell?

Thats what ill be doing! Dont want to dependent on lanthum :)

Let me know when you want come over the Lanthanum dark side ;) :D I am still skeptical on the long term use of lanthanum.
 
Do you have a refugium section in your sump? And if so, do you use it? I have absolutely zero Phosphates and do not use any chemicals besides carbon that I use off and on when I remember to change it. I have some Chaeto growing pretty good and figured that would be all I needed for Nitrate and Phosphate control, but I am no expert. Just figured I'd ask.
