High gh!

[revengeishere]

oh my, i just tested my water and the gh is 17! Will this harm my fishy? I have 10 tiger babrbs and 20 danios as well as 1 redtailed sharks, 1 syno eupteru, and a flying fox. I also have 2 bala sharks.

the tank size is 75 gallon. Kh is at 6 but gh is way over the top!

thanx.

edit:sorry if this is the wrong board. move this if appropriate.

Hi revengeishere.

What is the water out of your tap like, assuming that you are using tap water.

If it is at the same level, and the water at the LFS is the same, then you should be ok.
What is the pH.

I dunno yet, im looking at my local water district. last time i tested it, it was 5 or 6, i cant remember. Ill go research it some more.

here is what i found about my water quality.: http/www.ci.san-diego.ca.us/water/qualit...ity/index.shtml


what does "The level of hardness in our water is roughly equivalent to 12 grains per gallon" means?

 

[revengeishere]

I tested both tap water and my aquarium water. My tap is around 7.9-8.0 range. my aquarium water is about 7.8. Is the hardness ok?? I have some live plants in my aquarium. will they be ok?

Hi revengeishere

From a quick look at the water report, it would seem that the water out of your tap is hard and alkaline.

This is what you are seeing in your test results. The water should be very stable as the high mineral content will buffer any changes in the pH, due to the plants use of CO2, and the acidifing affect of the filteration process.

As the LFS will have the same water the fish should be condtioned to the water, and will be fine.

Good fish keeping.

So what your saying is that plants change the ph by consuming CO2? Anyways, there is no white deposits yet on my tank. Thnaks tho. Ill try calling up my local LFSs to see if they they have the same gh and kh as I do.

Again, thank you.

edit: I called them up and they told me they do use tap water and that they dont change it at all. But one more question. will my decor(a few stone caves, i dunno what they are made off) raise the hardness of my water?? Cos i did remember adding two hard corals(dead ones) from my other established tank to help with the bacteria colonies. is it advisable to use a water softener pillow?

thanx.

your right, here is the report found here: http/www.geocities.com/Heartland/Hills/2...7/technicl.html

From report by San Diego's Water Quality Lab:
pH: 8.11
Total/general hardness: 329 mg/L (CaCO3 equivalence) (18 dGH)
Carbonate/temporary hardness: 150 mg/L (bicarbonate) (8.4 dKH)
1.5 ppm chloramine most months, 2 to 3 ppm free chlorine one summer month each year.
Nitrate: 0.62 mg/L
Phosphate: not detected.
Measured with Aquarium Pharmaceuticals' test kits:
pH: 8.1
Total/general hardness: 14 dGH
Carbonate/temporary hardness: 7 dKH
Nitrate: 0
Phosphate: 0.

Hi revengeishere

Any calcium added to the tank, will raise the hardness, to some extent. As your pH is close to 8 the hardness will not rise much.
One more thing I picked out of the water report, is that the water has chloramines in it. so you must remove them from the water before adding it to your tank.

 

[revengeishere]

Thanx. i know about the chloramines and such. But whenever i do 20 % water change, i dont bother neutralizing it as i have a relatively established bacterial colonies.

Thanks for all your help.

When you say you don't bother neutralizing it does this mean you don't use a water conditioner for your tap water?
