Help with test reading


Hi guys! I just done a test for my aquarium. Here is the result and it seem Greek to me. I want to know how these reading look.

From left to right gh, carbon hardness, ph, nitrite, nitrate

I'm not particularly happy with most of the test strips I've used.. At one point I had a set of hot-tub measurement strips that worked fairly well, but most strips I've used have been terrible.

Poor color matches, picky about what time you read them at, wildly inaccurate, all common problems.

This one at least appears to have poor color match problems..

My best guess is it is trying to tell you (assuming my eye-match guesses are ok, and the test itself is accurate):

GH 180 ppm (about 10 dGH, you have fairly hard water)
KH 120 ppm (about 6.5 dKH, your water has normal carbonate alkalinity)
pH 7.5 normal
Nitrite 0 normal
Nitrate 40ppm a bit higher than needed for plant growth, but probably not hazardous to fish.

First on the left (bottom of bottle, I think)
GH. This is a measure of Calcium and Magnesium. The purple color seems like it is somewhere between 60- 120ppm, but on my monitor the bottle has blue tones, the tab on the strip looks purple.

KH. This is a measure of Carbonates and Bicarbonates. The pale-sea-green looks like it is in the mid-range of this test. I would call it 80ppm.

pH. This is a way of expressing how many H+ ions there are compared to OH- ions. I would read this as 7.0 or maybe a shade higher. Not quite to 7.5, though. Very slightly alkaline. (7.0 is neutral, lower than 7.0 is acidic)

NO2. Nitrite. This is toxic to the fish. Good, clean zero.

NO3. Nitrate. This is good for plants, not so good for fish. I am not sure if this is showing 20ppm. Light may not be right. 20 ppm is as high as I let my tanks get. I generally keep them between 5-10 ppm to keep the plants growing.

If you compared all these colored tabs at the correct timing for each, and used a good light (I usually stand near a window for bright but not direct sunlight) you may be able to fine tune the reading.

If these results are good or bad depends on the fish you want to keep.

GH and KH under 100 is generally good for most of the soft water fish like Tetras, Barbs, Cories, Loaches, Danios and many others.
GH and KH over 150 is generally good for most of the hardwater fish like Guppies, Mollies, Platies, many Rainbow fish, and the fish from the Rift Lakes of Africa.

If the KH is high, then the pH is usually high, and hard to change.
If the KH is low then the pH will be easy to change, and usually low, though other things in the water can make the pH high even if the KH is low.

Seeing no NO2, but yes NO3 suggests to me that the tank has completed its nitrogen cycle, and has enough bacteria for the current fish population. Test the ammonia, too, to be more sure of this.
Also, positive NO3 can be from fertilizers and have nothing to do with beneficial bacteria.

Bump: See- mattinmd and I are seeing things a bit differently- may be photo quality, monitor, test strip problem...

Thank for the reply guys. I actually have the api master test kit too but I figure I use the dip since I'm lazy lol. I actually want to see my gh and kh result. I been keeping angel, roseline shark and rainbows in this tank for 4 month. I dose nitrogen, phosphorus, flourish on 1 day and iron+potassium the next. maybe I should ease up on the nitrogen. I'm still trying to figure out my dosing regiment and how much I should dose. I also want to see if I can up my co2 a little more. What is the best way to know if it's safe? Will a drop checker do it? Im also trying to see if my water is good for keeping these kind of fish I just mention.
