What is Reddit's opinion of Etekcity High Accuracy Pocket Size Handheld pH Meter Pen Tester, Red?

From 3.5 billion Reddit comments

I'm testing pH with this meter. http://www.amazon.com/dp/B00NL0BVAY/ It was also calibrated when I first got it, this is like the third time using it in 5 months and using it as per the directions and rinsing with distilled water between uses.

Morning (before lights) pH reading is 7.53-7.55pH Tap water is testing as 7.95-7.98ph 10g next to this tank with the same plant life rocks and substrate is at 7.26pH (same before lights), but has 4 dwarf puffers, amano shrimp, a TON of MTS, and some CPD's. Nitrates are usually 20-40ppm though. This tank is getting the same 50% WC weekly along with the RCS tank. Much greater plant quantity in this tank.

I'll get the rest of the readings in a bit.

> I probably wouldn't keep mollies with angels, as they are from the opposite ends of the water hardness scale. That tank water is pretty good for angels; but it might be a bit soft for mollies.

Interesting, I have always heard it was a decent fit as long as you stayed towards the upper end of the hardness range for the angles. I will have to look into that further.

> What kind of dosage are we talking here? Also, how are you testing pH?

I am using API PH Down which is a 9.6% solution of sulfuric acid. Their recommended dosage is 2.5 ML per 25 gallon. This is the dosage I used. so overall 5 ml.

I am using the High Range PH test from the API Freshwater Master test kit. I have also been considering getting a digital tester like this one

>Probably wouldn't hurt. Not sure if it's necessary. What species are we talking about here?

I honestly have not decided yet. I wanted to verify I could find a good safe way to get my PH low enough for the water changes before I started choosing any fish.

The Etekcity pH meter (#1 best seller on Amazon...whatever that is worth haha).

I do trust it to a certain extent as I calibrate it once a week using standard 4.01 and 7.00 solutions from an analytical lab.
