ALK difference between Tank and Change water

Jason McKenzie · 07-16-2003, 03:08 PM

Just wondering what a safe difference in Alkalinity between the tank and the change water would be? I'm going to change 10G in my 75G and made a little mistake when adding buffer to the replacement water.

Thanks

How big of a difference are we talking about?

7 dKH in the Tank and 14dKH in the change water. I really messed up I used the amount of buffer for 75G in 10G of water. No prob though it's all worked out. I dumped enough water and topped up with RO/DI. Just finished a long over due water change.

just curious is your tank water 7dkh then? thats actually a little low its best if its in the 9-12 dkh range i would try and raise it a little bit if you could.

Ya it's always running low. I'm working on getting it up.
Thanks Karlas

Is dkh the same as alk?Cuz I use a sea chem test for alk and it says it should be between 4-6 meg/l mine came out at a 4.
I dose every day with 30cc each of b- ionic (it's a two part supplment) and twice a week with two capfuls of sea chem reef calcium should I try to raise my alk more?

4 meg/l is equal to 11.2dKH. That's in the range and quite good. It's like measuring distance in Km or miles basically.

So they are the same!Great j. Do you know the conversion?

could you post it? Thank You!!

1 dKH is equal to 2.8 meq/l

I'm getting this from Reef con pro. A great Aquarium management and log program.

Search google for it, there is a freeware version.
