alvin_varian Posted June 12, 2006 Share Posted June 12, 2006 hi all my 3x2x2 tank with sump, water parameter Ca out of range 5++ Kh 12.8 Alk 4.5 No3 0 mg 1200 PO4 0.2 all test with salifert performed 2 pail of water change using sealife salt, but Ca remain did not drop. Is the high Ca, Kh and Alk killing my coral??? pls advise . What should I do? wait for the Ca and Kh to drop by it own? Quote Link to comment Share on other sites More sharing options...
jervismun Posted June 12, 2006 Share Posted June 12, 2006 Sorry to hear that. Nothing to do with high Ca. Alk/Kh a tad high but not the culprit. Mg is perfect! PO4 is acceptable range also. How long have u been keeping them? What other corals u have in ur tank? Lighting? Temperature? Possibly salinity too.

SRC Member Altantis Posted June 12, 2006 SRC Member Share Posted June 12, 2006 My Ca was 620 in apr to 520 now... Hammer and bubble still growing. So I don't think it the Ca problem... Your kH and Alk is slightly high, should be 9-11 dkh or 3.2-3.9 meg/l respectively but still OK. Maybe lighting and flow Worst situation will be if Sg is off Quote Link to comment Share on other sites More sharing options...

SRC Member loster Posted June 12, 2006 SRC Member Share Posted June 12, 2006 your po4 too high for hard corals... some lps are sensitive to it. your sg is low too for corals... try to raise it slow to at least 1.023 wonder... you are running with FR... why your p04 still so high?

alvin_varian Posted June 13, 2006 Author Share Posted June 13, 2006 hi perform test again with salifert test kit Ca out of 500 range Mg 1200 Kh 9.6dkh Alk 3.43 NO3 0 and test PO4 with sera test kit PO4 0.25mg/l this happen when I start all this 3 wks ago 1.after dosing seachem calcium only 1 per week with 2 spoon. Dose about 3 times, now stop dosing and then start measuring after getting the measuring kit. 2. Adding Zonan Two 2 drops everyday 3. Adding one time 2 spoon of Reef Builder Can any of this cause the dieing of bubbles and melting of only one hammer? btw, the pearl is OK and others hammer OK.

SRC Member asg Posted June 13, 2006 SRC Member Share Posted June 13, 2006 Bro, get rid of the PO4, it is too high. you might want to consider showing a picture of your tank so that we can analysis from there...

alvin_varian Posted June 13, 2006 Author Share Posted June 13, 2006 hi the PO4 in the chart is the 2nd lowest, and test PO4 with sera test kit PO4 0.25mg/l . I throught that is low enough? Quote Link to comment Share on other sites More sharing options...
SRC Member asg Posted June 13, 2006 SRC Member Share Posted June 13, 2006 did you use any resin? rowa phos? to reduce the PO4... shall aim for undectable NO3 and PO4... and BTW, can i suggest that you try tropic marine proreef, it is one of the best salt and it might just be the answer to your problem...

SRC Member loster Posted June 14, 2006 SRC Member Share Posted June 14, 2006 if your p04 is higher than 0.1, it is critical for your reef. as i say, some ips are very sensitive to high p04. 1st, got to do something for your p04 2nd, stop dosing any additive 3rd, do water change to bring your off parameters down slowly. use good saltmix this is the parameters for the general reef tank as a guide: ph: 8 - 8.5 kh: 9 - 11 ca: 400 - 450ppm mg: 1200 - 1350ppm p04: <0.025ppm N03: <5ppm (not more than 20ppm) Quote Link to comment Share on other sites More sharing options...
SRC Member csloo Posted June 14, 2006 SRC Member Share Posted June 14, 2006 From my experince, Hammer melt (while other is just fine) due to: 1. Accidentally direct pour of additives to the hammer 2. Those undisolve powder form stick at them 3. Lack of iodine and strontium Hope it's help. Quote Link to comment Share on other sites More sharing options...
alvin_varian Posted June 14, 2006 Author Share Posted June 14, 2006 HI the sera test kit lowest is 0.2. You mean must get better PO4 test kit and low the PO4? btw, water change with coral life seem will not bring down calcium. Change salt?

SRC Member loster Posted June 14, 2006 SRC Member Share Posted June 14, 2006 ya... 0.2ppm is way too high and not all corals can take it. may be the reading is inaccurate cos if i am not mistaken, you mentioned that you are running FR with phos remover media. invest a good test kit. salifert is easy to use and fairly accurate ya... corallife saltmix ca is way too high. some batched have more than 600++ ppm. invest a good parameters saltmix. it is good to practice to test on at least ca, mg and kh of the new saltmix you purchase. at least you know the parameters of your saltmix before u pour it into your tank.
