I don’t think silicate is any issue, and I’d accept the Hanna value unless there was a different reason to suspect an issue.

4.9ppm phosphate?Thank you i suppose its time for some Water Changes

yes that was a typo .49ppm but even after skimming heavy and running a lot of phosguard for 24hrs.4.9ppm phosphate?
is that a typo?
I’d suspect test false reading of your Hanna.yes that was a typo .49ppm but even after skimming heavy and running a lot of phosguard for 24hrs.
just to clear things up that salifert test in the photo is a silica test. I have a really hard time trying to read the salifert phosphate test so i never/rarely use it.I’d suspect test false reading of your Hanna.
Salifert versus Hanna should not have that much flux.
You expected around .1ppm, Salifert reports same. Go with that.
Sometimes test results send us chasing numbers.
If your tank looks good, leave it.
Got it.just to clear things up that salifert test in the photo is a silica test. I have a really hard time trying to read the salifert phosphate test so i never/rarely use it.
I’d try that Salifert again if you still have it.just to clear things up that salifert test in the photo is a silica test. I have a really hard time trying to read the salifert phosphate test so i never/rarely use it.
Assuming 20ml, 8 drops and 2 scoops, that's close enough to the Hanna to not make a difference.This is the salifert phosphate high sensitivity test so the scale should be halved. But like i said i never use this test because i find i very hard to read and the hanna has allways been consistent
I dont have a reactor and have never used gfo i have used phosguard in the past which worked well with heavy skimming but overnight it hasn't made a difference. Its a small tank so ill do a 10% wc tomorrow to nudge it in the right direction and keep running fresh phosguard?Assuming 20ml, 8 drops and 2 scoops, that's close enough to the Hanna to not make a difference.
0.25 or 0.49 call it 0.38 if you like, just plan to get it down .
GFO will have no problem dropping that over a week or so.
Phosguard works for me too (I alternate Phosguard/GFO), but I use it in a reactor squished between some filter floss.I dont have a reactor and have never used gfo i have used phosguard in the past which worked well with heavy skimming but overnight it hasn't made a difference.

Thanks for that info! im going to do some more research on gfo and continue with the phosguard in the mean time.Phosguard works for me too (I alternate Phosguard/GFO), but I use it in a reactor squished between some filter floss.
Phosguard can leach Aluminium which GFO cleans up, and GFO leaches Barium which Phosguard cleans up. lol.
Put it somewhere with good flow where preferable the entire flow is forced through it.
Probably some phosphate has bound to Rock and substrate, so it may take a few changes of phosguard to get it down.
Mixed some new water last night and re tested this morning. and it tested .07. I'm not sure where the phosphate is coming from in my new water.i did test my rodi water after a 10% wc that seemed to have no effect on the tanks level. but did test 0

Thank you that certainly makes since but also makes we wonder if it has anything to do with why my tank being at .5 ppm0.07 ppm in top off and new salt water may be from escaping the RO/di, but it is not worth worrying about in most contexts. You add far more phosphate every day in feeding than this route provides.
