My 1.5 ft Reef log

[jackywongto]

25 Nov Test result

salinity 1.025

PH 8.0 - 8.45

KH = 7

ammonia 0

nitrite 0

phosphate - between 0 - 0.5 I really cannot differentiate the colour.

nitrate 10ppm. Strange.. where is this coming from. So lightly stocked.

Calcium 420 - great. Will try to increase this to approx 450.

Magnesium only 1100.

8 Dec Test Result

Salinity 1.025

PH: 8.0 - 8.37

KH = 8 (increased by 1)

ammonia, nitrite = 0

Phosphate = 0

Nitrate = 5ppm (dropped despite higher stocking level. Did the clams played a part?)

Cal 420 (maintained)

Mg 1150. ( I have been dosing very conservatively. Guess I can increase to the reccommended dosage amount 15 - 20ml per 20 gallon)

Looking at the reading on the 8 Dec, does that mean I can space out my WC to another week longer?

Pls advise, gurus.

Well, based on your readings, yes you can.

Nitrate levels may have dropped due to your using of the sea squirt for feeding which means more efficient feeding.

Some nitrate is good for mushrooms and yr LPS...they need some nutrients..unless u intend to keep lots of SPS.

For yr nano size, you have to do alternate day 5% water change instead of weekly 10%-20% water change as this will cause the water parameters and temp to change drastically.

Alt day 5% ?? .... think I will not be able to afford the time to do that.

ORP

The oxidation reduction potential (ORP) of marine aquaria is a measure of the relative oxidizing power of the water. It has often been recommended to aquarists as an important water parameter, and some companies sell products (equipment and chemicals) designed to control ORP. Many who recommended ORP control have convinced aquarists that it is a measure of the relative "purity" of aquarium water, despite the fact that this has not been clearly demonstrated.

ORP, at its heart, is very, very complicated. It is, perhaps, the single most complicated chemical feature of marine aquaria that aquarists will typically encounter. It is not hard just for aquarists who are not scientists. I had to learn a great deal about the electrochemistry of natural waters in order to write this article, and had help from a number of other chemists in understanding some of the principles that are usually swept under the rug. ORP involves many chemical details that are simply unknown, either for seawater or for aquaria. It involves processes that are not at equilibrium, and so are difficult to understand and predict. Even more daunting is the fact that the chemical species that control ORP in one aquarium might not even be the same chemicals that control ORP in another aquarium, or in natural seawater.

Because of these complexities, this article is split into two parts: a simplified part and a detailed part. The first part explains what ORP is and why one might measure or control it, in terms that any aquarist can readily understand. It does not, however, explain any of the science behind ORP. It will be useful for aquarists that want a simple understanding of what ORP is in the context of a reef aquarium.

The second half goes into great detail on the science behind ORP, including extensive discussions about what facts simply are not known. Many of the details in that part are important to truly understanding what ORP means to aquaria. Unfortunately, these facts have often been glossed over, or ignored entirely, by aquarists using ORP measurements. Such details will help aquarists better understand whether or not it is a good idea to control ORP, to understand the difficulties in attaining interpretable measurements, and to understand what ORP readings are actually telling them about their aquaria.

CF NSW

$2 for about 10 litre.

did a detail test on the NSW quality and here's the result:

Salinity : 1.025

PH : 8.18

Ammonia : 0

Nitrite : 0

Nitrate 10ppm

Calcium 520 ppm

Phosphate : 2ppm

Mg : 1080 ppm

Alkalinity : 6 dKH

* I am a little surprised about the level of the phosphate and nitrate.

will do a salt mix with ME salt with distill water and do another set f test later.

It's inevitable for NSW to have some phosphate or nitrate given that there will be some dead-offs inside the water. That is why it is not recommended to keep NSW in jerry cans for too long (:

I'm surprised that alkalinity is 6 for NSW. ahaha.

2ppm Phosphate is not "some" , i think it is quite a lot right?

**gulp....

- dosing so much additives and then do water change that lower the readings.... it is like slapping your left cheek with your right hand.

- wanna reduce nitrate and phosphate, thats why changing water but end up with higher nitrate and phosphate. ... this one you slap your right cheek with left hand lol

you get my chain of thoughts here?

wonder what is the salt mix readings?

Phosphates can be reduced using RowaPhos or other phosphate media. But I'm quite surprised that the phosphate level is so high. Victor's NSW seems to be 0ppm for phosphates and nitrates even after i store for a month.

Salt mix typically will be 0ppm for nitrates and phosphates unless the water u use for mixing has nitrates and phosphates.

hey next time do a full test then post the result Pete.

Found this fella again.

Since no fishes has been found died mysteriously yet, I am letting him be for the time being.

if anyone can confirm that he is harmful, pls let me know and I will get rid of it.

then this is the same worm I saw 1 month back

[jackywongto]

ok after witnessing my coco worm pooping, I think I caught my clam doing it too.

Can anyone advise if this is excrement from the clam?

piangz.. why do you always see ur LS poopoo???

after you post about your coco poop, i've been observing mine waiting to witness it too.. but nothing lehz..

Your photo is blurry, it looks like a centipede from what i can see so I am guessing it is a bristleworm.

I fished a dead (i put the rocks in super hyposalinity water) 1.5 to 2 feet long specimen out of live rock I got from another reefer recently.

I have another one living in a rock in my old tank that i haven't decided what to do with.

It is debatable whether it is harmful to the tank since i believe nearly all tanks have them....

generally small specimens are harmless scavengers that keep the tank clean but giant specimens can eat snails and other ls....

you are missing all the action bro

Took some photos under blue lighting.

Thanks for these Peter. They really look cute.

BTW, the 3rd bunch really did not make it RIP.

The surviving 7 polyps should do well.

This SPS has a green tinge to it but it nvr colours up in full LED lighting.

Orange Yuma

Green Hairy Mushroom

Another Green SPS

The white skeleton portion seems to be diminishing.

The flourescent green mushroom

Wow...bright headlights...

Never mind...at least you still got 7 surviving polyps...

Too bad I couldn't frag out some of the red ones for you as they are epoxy on my LR already and I don't want to take it out and epoxy it again later. Too troublesome already.

Your orange Yuma seems a bit dull. Try target feeding it with some frozen food. It should colour up gradually.

no worries. I appreciate these very much.

Where's the pic of the blasto???

too busy taking Ray's that I forgot to take mine.

Now lights off already ... haha

Ahhhh...don't want Ray to see that yours is nicer huh???

wa bes nv share the blasto

[teebs]

A pic of Jacky's blasto in my tank... I'm very sure it will look different from this in his tank under his LED lights.
