Drop Checker & 4dKH Solution?

I got one through the post along with some 4dKH solution.

In the instructions for the drop checker it didn't mention adding the 4dKH solution, but today reading George's artical in PFK, it says to add some along with the reagent.

So, have I gone wrong?

You use the 4dKH solution instead of the tank water that is usually recommended in the instructions to most drop checkers. So you add 4dKH solution and the pH reagent to your drop checker.

Hmm it's been two days now since my water change and using the method mentioned above.

The colour has remained at yellow when my bubble rate has remained at the same level.

I guess that the water change lowered the CO2, but would of thought that it would of caught up?

Oh dog doo, the yellow shows too much CO2.

I got it the wrong way round, I've been adding too much. Turned down the bubble rate doh!

I was going to mention that on your journal! From your diffusor it looks like you are flooding it ;)
Won't last you very long at that rate, the plants will thank you for it, but at that rate you need to keep dosing those ferts pretty high or you will have algea issue ;)

Think it's just taking time for me to get the right injection of CO2 into the tank.

Think those bubbles showed from when it just turned on and loads of bubbles were pushed through at the start.

It's a shame that I've not had a full day to keep checking the drop checker and the bubble counter, as I'm always out at the weekend doing games.

Just do small adjustements at a time, its takes a while for the bubble rate to be accurate, at least 10 minutes, and the colour of the drop checker takes even longer, from what I read can take up to 2/3 hours (correct me if I am wrong).
I have a bubble counter, but the bubble are so tiny I can't really count them properly, so I just go by the drop checker and the plant health overall ;)

Could be then that my bubbles are rather large! :oops:

Don't concentrate a lot on the bubble rate, concentrate more on the drop checker and its green colour ;)
There are lot of different bubble counters out there and its difficult to say what is the right bubble rate.

I turned down my bubble rate last night and it was going at about 1 per 2 or 3 seconds. To be honest, it looked as though it was off!

My drop checker was still yellow this morning, my water must of been like lemonade! :rolleyes:

Best get looking for a Co2 FE

Please note I'm a total numpty!

I was using the wrong reagent bottle for the drop checker. I was using a kH test! So no wonder it was always yellow with the 4dKH solution!

So just changed it to use the proper stuff.

I feel such an idiot!

I can't believe you just admitted that. I'd have swore blind that black was white if it came down to it ;)

I don't mind owning up to my errors. It's blue at the minute, guess it'll take a while to take the reading. Will have a look at it in the morning.
