Marine lab test results thoughts.

[cchomistek]

Hi Randy

Any thoughts on these test results?? Anything way out of the ordinary?

Thanks

Nothing looks especially problematic.

Are you using any type of white media (Phosguard/ MarinePure?) that might be a source of aluminum? It's not critically high, just curious.

Nope I am not using phosguard or marinepure. Never have on this tank either. I was using aquaforest component 123 but have stopped and went back to Randy's recipe for calc and alk. I have some ATI elements that I may try out in awhile.

Your results are excellent. One of the best ive seen.

Are you having any problems with the tank that prompted an icp test?

 

[cchomistek]

Thanks Cory. Perfect I am not sure of.

I had the tank running with next to no maintenance being done for about 4 years and was basically fowlr and tap water.

Now I am getting back to wanting coral and a nice reef tank. So RO water it is and keeping the water chemistry where it needs to be. I put in some coral but it did not do very well. I had some issue with Cyano and and now I am fighting off dinos which I seem to be winning and now some green hair algae so things are moving in the right direction and the coral I put in about a month ago are looking ok.

What coral is it? Your po4 is slightly elevated, which would intice algae growth. Do you know your no3?

Also if your goal is keeping coral you might want to raise the salinity to 35ppt not 33ppt.

Yeah phosphate is a bit high but not high enough to make them parish. Might brown out. I now have a milli and a stylophora that have been in the tank just over a week and polyps are out and color is sustained.

The corals that parished were a Duncan frag and a euphylia and blasto. Hopefully things are moving in the right direction.

Nitrates are now around 15 ppm. Also 33 PPT is 1.025 which is ok for coral. 35 PPT is 1.026. do not much difference but yeah I could raise it up.

How long did it take for those coral to die? Lost flesh or bleached?

If it were my tank id raise it to 35ppt. Most coral dont live in water thats 33ppt for extended lengths of time. But it may be fine. Id rather take the approach of better safe than sorry.

What did your refractometer say the sg was?

 

[cchomistek]

They slowly died off. Refractometer reads 1.025

I see you said tap water was used for the top off. I do not see chlorine being tested for on your lab results (may have missed it). Were you going straight from tap to tank? When did you switch over to RO/DI in relation to adding the first corals?

Chlorine cannot be tested by ICP. It looks identical by ICP to chloride, the most abundant ion in seawater.

 

[cchomistek]

Prime was used so yeah not straight tap water. Figured that was self explanatory. Sorry for the confusion.

As I suspected, something in the water must not be quite right for the coral. Yesterday my new milli frag of about 10 days started to STN from the bottom. I guess there is a possibility of flat worms as I have not dipped it yet but there was no sign of bite marks or eggs when it came in. So something is a miss even though the ICP test showed decent results.

May ask what type of salt your using?

 

[cchomistek]

I am using h2ocean salt.

 

[Finhead]

So the elevated Aluminum in this ICP is of no concern?

 

[cchomistek]

It is elevated but not off the charts I don't think.

It’s likely of little concern if leather corals are fine and if it doesn’t get higher.

I have one toad stool that is living but not growing a tonne but not receading. As for the sps STN'ing I am unsure about why that might be at this time. Frustrated...

I do not see an explanation of the SPS issue.
