View Full Version : need to lower pH - big time in a hurry.

I need to lower my pH. I added Kalk last night and when I got home my Xenia seemed to have crashed big time. It has grown tremendously over the past 6 months from a single shoot to about 6 7 big pieces.

I started checking my water parameters and 1st thing I check was my Ph and it read over 9.0. I have been adding Kalk for the past 3 months and this has never happened before. I did add a little more than normal but only a teaspoon more.

I did a 20% water change and I will test again in an hour. Stupid me I did not test for alk, nitrates etc.

The rest of the clams still look good and the fish look OK. I have turned off the light and I will maybe do another water change around 10:00. at that time I will test the rest.

Can anyone make a suggestion about how I can lower my pH?

Patrick, I'd probably just keep doing what you're doing. Dropping it quickly wouldn't be a good thing. Did this happen with a drip setup? Maybe check for leaks or other problemswith your dispensing method.

Turning your skimmer and reversed lighting off aids in a small bit. Other than that, water change is the safest way.

Forgot. If you run a ca reactor, increase the effluent rate super fast, with caution though.

The water changes helped and I turned off the lighting and skimmer for the night. I checked this morning and pH is getting better. Still a little high but I will do another 20% water change tonight.

Really ****es me off. :mad:

The Xenia looked awesome. They looked like a swaying little forest that my clown hid in. I heard that Xenia are like that. They can live for a long time, and them bam they die. I was looking at doing some fraggin and selling it to Kevin’s for some equipment, now I don’t know if I should try again.

Andrew – you have a lot of Xenia, have you ever had a crash and what caused it?

Thanks all

Hey Patrick, glad to hear your pH is getting back to normal.

I have had my Xenia crash once before as well, and it was due to the same thing, pH burn. I rather foolishly dumped in the remaining kalk solution from my Aquadose, and I guess the Xenia are pretty sensitive as half of my mother colony shrank away and disintegrated. It has recovered nicely, but it took 2 months. Oddly enough, none of the other corals/fish were affected.

Anyways, just stablize things and it should make a recovery. Keep you Alk high and your pH stable. If the Xenia doesn't make it, come by and I'll give you another frag.

in emegency Vinegar or gaseifed water (club soda or mineral water)would work but you need a PH meter

Just did another water change. A lot better water parameters now.

What a stench those dead Xenia made. Smelt like rotten eggs. I had make sure I kept all the paper towel and brushes used to clean the rock and through everything in the garbage.

Thanks for everyones help.
