Does anyone have any experience with the Seachem pH alert series?
I am just wondering how accurate they are.
Which pH kit would you guys recommend?

Ive tried API and Aqua one series and both show a reading of 6.8 and 6.4 respectively.
Although they are not off by much I dont really know which one is correct

Well you could look up how to make reference solutions to measure properly.. or buy a digital probe and calibrate it often.
I am also interested in the ph alert series.. so i'd love to know... titration or drop test kits arent very accurate. They just give us an idea.. too much human error and external factors play a role in how they read.

cause i can :) that's pretty much the basis of my hobby. i TOTALLY enjoy it. right down to scraping algae or nurturing a sick fish or unhealthy plant.
why monitor ph? why not? it gives me more info on what's happening on a regular basis at a glance :) not that im worried about it. just wanna see it

I have a three place digital pH meter that is regularly calibrated and I never use it on my planted tank water!
I have a CO2 controller and I set it for a CO2 level of about 20 ppm. I check it using a calibrated drop checker. If my drop checker is green and my CO2 level is steady, My pH is always OK!

Well for me i use co2 injection and monitoring Ph is vital

Not vital what so ever if you are starting with a good Ph. Watch your fish. Watch your plants.

I inject co2 in all of my tanks. I know that my Ph is good in all of my tanks. Injecting co2 changes my Ph while injecting, of course. It is not anything to worry about though. Fluctuations are expected while injecting.

Problem is I have two test kits with different readings. One says 6.1 other says 6.8. I have Ada soil so I'm confident it's 6.1. I also have crs that are sensitive to low ph as it melts their calcium hardened carapace. 6.1 is okay but if I inject too much co2 it may drop to 5.x and I wanted something to monitor it with. My drop checker doesn't work and is always orange even tho I haven't started co2 yet. I suspect it's my low kh but I rather not dose with bicarbonate as it has salt and will raise my gh

If your drop checker is orange you are using the wrong pH reagent. API pH reagent is the one to use, or any similar one that is blue at pH of 7.2 and yellow at a pH of 6. I know CO2 is not good with shrimp, especially if you want them to breed, but I'm not so sure that pH is a problem. The Shrimp forum would be a good place to get an answer to that.

Oh I just checked the solution at home.
The manual tells me to add the pH solution that came with the vial to a sample of my tank water. mix it up and put it in the drop checker.

I know my tank water is kH 0 so the solution would have been 0kH. Should i start again with a 4dkH solution?
Will it still work with my tank which has 0dKH?

well a 0dkh tank needs to be fixed.. u need at least 1 dkh for c02 buffering.. kh helps with carbonic acid buildup.....

so ur reagent most likely could be staying orange for that reason.. 4 dkh is the most accurate solution that has been found.. 3 and it will prematurely turn yellow. 5 and it won't turn green until u almost have too much ( by most standards) mineruns yellow at 60-80 ppm c02 but i've got a little practice under my belt. " a little practice" i still dont understand the whole system but i know how to keep fishies and plants happy with high c02 now
