How much rowaphos

[yanni]

Hey all!

I’ve been tracking my phosphate levels since my GHA has been blooming, I manually remove as much as I can once a week, but it grows back so quick. I have detectable nutrients

phos: 0.16
no3: 10

phos has been raising 0.005 a day, I tested 10 days ago at 0.11, now today at 0.16, so 0.005 checks out. Contemplating rowaphos additions or keeping up with larger wc, then maintaining wcs to keep up at around 0.05 ish

I feel like lowering phos may definitely help, all corals seem super happy, nems look great, all inverts doing well. Confused why my GHA is blooming, but still have detectable nutrients As well


Im thinking of running rowaphos for a while, just wondering how much? The online instructions are confusing me

 

[yanni]

that was a very disjointed thought process.

TLDR: WC or rowaphos to lower and maintain phosphate

If rowaphos, how much should I use? Will be in a media bag in an AIO media basket

Did you start with dry rocks? Dry rocks can leach phosphate for a long time, my rocks leached phosphate for 2 years. If that's what is happening to you, then GFO will be more effective than water changes.

I've tried rowaphos in a media bag, and also used a media reactor, the media reactor provides much more benefit, its really the way GFO is supposed to be used.

What size is the tank?

It was live rock, but live as in had been barrel baking for 4 months, still very sterile tho. I only have a Waterbox 20, not sure how I’d make a media reactor for it. May be a way tho

20g, Waterbox aio

I think you would find some aluminium oxide phosphate absorber like Phosguard in a bag would work better than GFO.

I use it in my 13gal nano and it works well.

I’ll have to see if it’s available in Australia, but I’ll keep it in mind !!

It is available - I'm in Sydney

Buy the large container and it'll keep you going for years.

Legend. I’ll try pick some up, do you find it more effective than rowaphos?

g’day to another Aussie reefer

Well, Rowaphos is just GFO, the same as Aquaforest Phosphate Minus and others.

GFO works very well when tumbled in a reactor and I use it in my 75 gal system.

For smaller systems without a reactor, putting a bag of any aluminium based phosphate absorber such as Phosguard into the water flow in the filter is easier, and just as effective.

I also have a waterbox 20, and have innovative marine's desktop reactor in the middle sump chamber running rowaphos to keep my phosphates in check. I used the rowaphos calculator to determine how much to run (only a tablespoon, so rowaphos lasts a while). So far it works like a champ and is easy to set up and dial in. The biggest problem is making sure you don't bottom out phosphate in our small tanks. Remember things move faster in our tanks than higher volume tanks!!!
