I see, thank you. Lets continue with you dosing regimen to see if the PO4 level does slowly decrease over the next couple of weeks. Additional I would recommend to vacuum the sand regular while doing the water changes for some time. There is a big difference of the PO4 level (Sailifert / Hanna) , what do you think is the correct result ?

I got .3 on the Hanna this morning. I'm not sure which one is accurate but I will vacuum the sand Saturday and continue on with this regime. We water change 20 gal. Every Saturday morning and my test results are done right BEFORE that. Do you think the results show that, as in maybe I should test AFTER the water change?
Everything looks good except the gorgonian and my Kenya tree which don't look dead but are looking a little 'shrunk'.Thanks

I never had paid attention when doing the water tests but I would not test recently after changes like a water change. Not sure which kind of gorgonian it is but many are really difficult to keep.

Today’s results
Ph 8.0
Am, nitrite and nitrate still at 0
Mag* 1160 (this seems low)
Cal 435
Pot 410
Kh 161
Phosphates using 3 different test! Hanna .8, seachem .08 and then seifert 0.
Phosphates tests vary so much that I’m unsure I can get any accuracy (each of the above were tested twice and the Hanna had 2 different results with the same test vile so I’m pretty sure it sucks.
Water change day is today so I’m not sure if the mag will boost.
Any advice you have is welcome. Same dosing regiment and flow remains constant at 160.
Thanks

Because of the PO4 level it could be helpful to know how the corals are looking. Do they have lighter or darker tissue, what about growth and poly expansion ?

Can you also measure the Mg level of your slat mix next time you do a water change ? Should be around 1300 mg. The level in your last post was much higher, unusual that this level does decrease so quick.

Two weeks since your first ZeoVit exchange have already passed so it might be the right time to switch the reactor to continuous flow if all corals are doing fine or have you changed this already ?

You had me switch to continuous flow at 4 weeks.
Coral wise everything looks good, we have growth and everything is opening up except the sun polyp.

As a note had to change salt two weeks ago as the Lfs stopped carrying mine. Switched to vibrant sea from the same company....I tested my water change water and before water change and it’s only 1140.

Tubastrea Corals are difficult to keep as they do need direct feeding so this kind of coral is not a really good indicator for SPS corals.

Because of the low Mg level of the salt you use I would recommend you to switch to a different salt mix with a adequate level. After a couple of water changes it should be within the recommended range again.

The pictures are very blue and small so I can not see much to justice the PO4 level.

Can you please repeat the Hanna PO4 test to see if the result is really 0.8 mg ?

With a PO4 level that high corals are usually all brown without growth.

All of these have grown since the start of this process. The acropora was about a half inch shorter and there were no polyps on it at all....we actually though it was dead but now we are seeing growth. The chalice has also become larger and still has good color as well.
I will re-test po4 and change my salt to raise mag.Thank you

0.4 mg is massive, looks like the PO4 has accumulated in the past in the system and does now leach back in the water column where you can detect it with the test.

Do you still have running the refugium ?

No refugium. Empty sump. I’m really not sure the Hanna is correct though as I can test 2-3 times and get multiple readings. The salfert reads 0 and the seachem is less than .1.
We have been vacuuming sand a little at a time and we get good skim daily....wouldn’t I have a algae problem if it were really that high? I’d omt have any algea to speak of??
Where do we go from here if, I’m fact, our po4 is that high?
Thanks
