My 1.5ft Reef Log III

photos incoming.......

1 set of HI 755 Alkalinity checker for myself and the HI 736 checker for Larry.

** Oh ya 1 more thing, Hanna Instruments only accept Cash, no nets or credit cards.....

I had to borrow $$ from my wife to pay for these.... thank goodness she was around.... (** funny thing is that she did not flip on hearing the cost... phew....)

The checkers comes in a nice white casing.....

[jackywongto]

The items are securedly placed in the black plastic mould.

Battery provided, comes with a liquid reagent, 2 curvettes and a syringe.

Closeup look at the curvettes.

Take extra precaution not to scratch or leave your fingerprints on these curvettes. It will impair the accuracy of the reading.

This is one of my major dislike. How not to leave finger prints on it when you need to hold it, add reagents, shake the curvette etc etc.....

Should ask Hanna come and demo it ....

HI 755 Alkalinity Reagent - Liquid form.

According to RC postings, the earlier version of Alkalinity checker which uses powder form reagents had issue with performance.

Hanna looked into the issue and rectified that by providing liquid reagent.

Lets hope that they will eventually change all the reagents to liquid form - so much more user friendly.

I bought an extra reagent for the alkalinity checker.

It comes with expiry date

There is a plastic mould to hold the reagent in place securedly.

Its comes with a set of syringe

On the other side of the plastic mould

and finally within the mould . Quote well packed, don't you think so?

[jackywongto]

The alkalinity checker box is almost double the phosphorus ULR checker box.

Most likely due to the bottle of liquid reagent.

The Phosphorus checker only comes with extra 6 satchet of reagents (for 6 tests) while the Alkalinity checker comes with the full bottle of reagents which allows you to test 25 times.

Definitely a much better deal. Just wondering if Hanna will increase the price once the public confidence on this checker is back.

10ml Syringe

The curvettes require 10 ml of tank water for each test.

My syringe is 6 ml and I have to add 2x 5ml each time I do the test.

Rather cumbersome. Bought a 10 ml syringe today.

This will make things slight easier

Jacky, will you be comparing the result from this toy vs salifert?

Jacky, will you be comparing the result from this toy vs salifert?

Was intending to use the D&D test kit to compare against the Hanna's but unfortunately I have returned it.

Anyone has Alk tester to loan ? Or maybe I can bring this to Cedric place next week so you can have a look at it together with the Phosphorus tester.

Just did my test and my Alkalinity is at 115 ppm = 6.496 Dkh. Rather low. Let's hope the Ca and Mg level is much higher. BTW, I used Brightwell Salt.

Will be getting the Tropic Marine Ca / Mg Tester on Wednesday so will just do a check and buff these up to the right level before I start stocking.

The Alk is really much easier than the phosphorus checker.

- liquid reagent. just invert curvette 5 times. no need to twirl for 2 mins to ensure powder dissolves totally

- almost instant result. Phosphorus have to wait for 3 mins. Alkalinity result is almost instant.

Simply love it !

Did my PO4 test just.

3rd Aug : PO4 = 0.502 ppm

4th Aug : PO4 = 0.502 ppm, added 4 tablespoon of High Capacity GFO in a filterbag and placed into my MCE 600.

5th Aug : PO4 = 0.374 ppm

6th Aug : PO4 = 0.350 ppm

7th Aug : Added 8 tablespoon of HC GRO

8th Aug : PO4 = 0.285 ppm

Looking forward to bringing it below 0.1 ppm.

Hi Sherman.

Yeah I got it from there. The checkers are S$81 each. Phosphorus reagents are S$12.50 while Alkalinity Phosphorus reagents are S$13.50.

All prices before GST. Cheers

Installed my pinpoint probe today. The reading started from 100.

Then I went out for breakfast and came back.

The reading started fluctuating from 260 to 310 non-stop.

Not sure if it is a probe issue or monitor issue.

Henry advised to placed the probe back into the tiny probe bottle provided with freshwater and let it settle for 1 day.

I did just that and in the mean time also monitored the value. The ORP is dropping gradually from 260 to 230 after 3 - 4 hrs.

Hopefully my monitor is ok....
