Dear All,

Sorry , in case my questions appears to you (professional aquarist) like kindergarten students (as I am new to this hobbyist and learning):

after a long period of waiting, is the water levels down below is goo denough for me to starting putting corals sps? test thru API :

1) NO3 ----15 ppm
2) CA -----400
3) P04 ----0.5
4) KH -----11
5) sp. gravity--1.024
6) PH -----8.3

right now, there is some fish in my aquarium but after I have almost all the corals dead, I have been working too hard to stabilizes my aquarium environment. I don't. know if the baove levels is good enough for me to start putting some corals?

Cheers,

MD

PO4 is high. Less than 0.10ppm is a good place to start and then you may want to go lower depending on your tank, nuisance algae and the corals you wish to keep.FWIW it measures .03 to .05ppm in my system.

Sg would be better at 1.026 ,imo; 1.024 is ok though

KH is at the high end of the recommended range and is ok.

You just need something to start dealing with your NO3 and PO4. There are many choices available such as a refugium, biopellets, or just good old fashion regular water changes.

I use Seachem Phosguard to drop my Po4 from 1 to 0.5 but it stay there. I wonder if I need to change a new lots to further reduces it.

Please advise.

for so many months, I try to lower down my NO3 and PO4. I have a No3 reactor (Jns NR1+Deniballs, but this is too slow) so I added vodka dosing , as of now 3.5 ml going to 4.1 next week. but No3 maintain at 15 ppm level. so I am thinking to co-dosing with vinegar (28ml), not yet dosing Vinegar , just plannint to do so.

for the PO4, I use Seachem Phosguard of which it helps reduce from 1 ppm to 0.5ppm. but it stay there, so I am thinking to change a new batch to further lower the PO4.

Yes, phosphate binders of all types deplete very fast at such high levels, and you likely need to change it.
