Thesis Statement On A Raisin In The Sun

played the small chemical changes to my

Finally I came all the tests and now in this sad rainy day I delight to do the little chemical.

Then report them 'on site analysis, very nice http://www.reefportal.it that gives you the ability to monitor the progress of the tank over time and the link with the results published in various forums with special tags.

Here are the results:

density salinity 34 1024

pH 8.5

no2 0

no3 40

kh 9.7

alk 3:45

about 480

mg 1380

PO4 0

tests I use are: PH test
jbl (excellent)
jbl
Mg or Ca evening evening.
PO4 PRODAC
Salifert KH for No2 and No3

and attaching to the instructions in Italian in the box as there are only in German and English.

TEST Salifert KH / Alkalinity '

· A) Put in clear container, using 5 ml syringe, 4 ml of aquarium water into the container for testing. 8For precision but lower for a greater number of tests used instead of 4 2ml

· B) Shake the dropper bottle of KH-Ind and add two drops in the container for testing (1 drop in the low-precision mode)

· C) strongly Place the plastic tip on the syringe 1 ml of reagent KH and fill until the lowest point of the black part of the piston is exactly 1.00 ml. The air in the syringe does not affect the test.

· D) Add dropwise with the 1 ml syringe the KH reagent water in the container for testing. Stir after each drop for a second or two. Keep it up until the liquid will not change da un colore blu/verde ad un colore arancio-rosso o rosato.

· E)Tenete la siringa difronte a voi con la punta rivolta verso l’alto e leggete la posizione, ora della parte superiore, della parte nera del pistone. La siringa è graduata in intervalli di 0.01 ml. Leggete il KH o AK attraverso la tavola di comparazione oppure calcolatelo come segue. KH in dKH=(1-valore letto allo stadio E)x16 Alk in meq/l=(1-valore letto allo stadio E)x5.71

Se avete scelto la bassa precisione moltiplicate per due. L’acqua marina in natura ha un KH di 8 o un alcalinità di 2,9.

Il reagente KH-Ind contiene un colorante, prestate attenzione a non macchiare i tessuti. Keep out of reach of children.

TEST Salifert Nitrate (NO3)
The water temperature should be above 18 ° C , otherwise the color is not achieved within 60 seconds.
Keep out of reach of children. Inedible.

PERFORMANCE OF TEST
1) Put 1.0 ml of water into the container to be tested.
2) Add a spoon of NO3-1 and mix gently for 10 seconds.
3) Add a spoon of NO3-2, mix gently for 30 seconds and then wait for 3 minutes.
4) Place the tube open on the scale, look down and read the corresponding value, unless it is practically zero, then you look at the tube side with the color scale back, read the corresponding value and divide it x 10.

recap:
Top view does not divide x 10. Viewed from the side
divide by 10.

Warning: 1ml is very little and is easy to misinterpret a color ..
My advice is to always use the same source of light for further tests in order to understand the least change (eg, aquarium lighting, sunlight ..).

Salifert NITRITE TEST
rinse la provetta e con la siringa in dotazione aggiungere 1 ml di acqua, aggiungere 1 cucchiaino (in dotazione)del reagente NO2-1 agitare per 20sec, attendere 3 minuti e controllare il colore
