Bad Rock!!!!

[Flexy]

I been trying to lower my PH for 2 month with peat and acids with no results at all. Now I have solved a problem. I have removed big rock from my tank which was making my water hard.

To test if you rocks are safe, put some acid on it and see if it will react. I had bubbles forming and shhhhhhhhhhhhhhhhhhh..... After removing it Ph have droped drastically.

Sounds like you were swimming upstream. Good problem solving.

How much was it affecting the pH? Do you know what kind of rock it is?

[Flexy]

It was brown one with some white layers in the middle. Rock had lots of layers and it looked like it was covered in rust. It kept the ph at 7.5 went down to 6.0 now.

[Ralph]

That is a major difference, hope your fish didn't go into shock with the change. I would never have guessed that a rock would make that much difference.

[Flexy]

Fish is fine. That happaned in like 2 days.

Probably was limestone. Joe

Did you notice a change in your gH as well?

[Flexy]

I am not sure about that. Didn't take any readings.

[Francisco_Borrero]

That rock sounds like what they call holey rock, and it is limestone. It will definitely leach stuff out.
Good detective work.
Cheers, Francisco.

Holey Rock batman! ;D

hmmmmmmm strange when I was a little kid (longggggggggggggggggggggg time ago) and had my first tank, I didn't know anything about Gh, Kh, Ph, CO2, RO, etc. in other woords all the things most people need now to keep a simple Discus alive. But first thing I learned was the acid on rocks/stone test. Funny now it looks like Flexy invented the wheel again :) :) :) Hans.

Hans, C'mon Lad, When you and I arrived on the scene in 954 BC,-- they hadn't invented kids as yet! Both being relics from the stone age, we knew plenty of our surroundings. 8)It was written on our cave condominium walls! I was hit quite often by the layered rock and such at the cave entrance. I feel it hasn't affected me at all. The Frontal Lobotomy got rid of the voices! My mother chased away the Wooly Mammoth with what was the precurser to Draino and walla, fizzy rocks! A more contemporary example is that of Jimi Hendrix. He would still be as alive as the archaic Mick Jagger today had he only known. He would have never attempted the blotter acid in the corner of his eye, because he would have known it was not good when his pupils fizzed--had he been an Aquarist! Everyone knows, pupils are of a rock composition---Geeeez, I learned that in the Ice Age! Instead HE Fizzed Out! Next thread --Had Elvis only known about Detritus poisoning caused by the toilet backup! :o

You and I as a team can tear down the Berlin Wall of Myth and Misconceptions! Setting the record straight with helpful but oftentimes puzzling analogies! Your public servant,,Joe :

I'm always interested in the twists and turns that a thread can take. I don't remember one though that went from fish to Elvis's bowel problems.

Thanks, I needed a laugh.

Now friends you can see Joe is even older as me, ha ha ha ha, Hans.

as far as things go when putting in my aquarium i always make sure they are safe first ... you can boil things in water and let stay there for a while ... this usually solves the problems unless you can see that the rock or item still has problems tehn i would just sratch that idea and find something else

[slicksta]

......sounds like the stones you find at the pet chains....Tufa stone...I think the name is.....basically limestone....and a definite pH raiser....great for an African cichlid tank.....NG for discus...
