Gh extremely high!!!!

I just tested my gh kh and ph and nitrates out of curiosity.

My gh tested at 11
It took 11 drops to go from orange to green. This is bad

Kh is one

Nitrates is 0

And my ph is quite high still. Around 7-7.2
For me this is a lot higher than I want it. I like to keep it around 6.4
I have neos and carids
Snowballs
Rcs
CBS and crs
And a few blonde orange eye tigers

My tds is solid at 200

What's in the tank is a manzanita branch
Ryouh stone
Cholla wood
Alder cones
Ceramic moss plates
Bee balls
I know the though stone raises ph, but does it also raise gh?
I have taken half of it out already.

I use or water only remineralized with salty shrimp mineral plus
And I do weekly top offs and wc every two weeks.

Filter media is only bio media and sponges and I run a sponge winter in the tank as well.

Any ideas what's going on here and how to fix it, I have shrimp breeding in this water and also shrimplets that I'm worried about, shrimplets include crs CBS and rcs.

must....have.....more....moss n shrimp!!!!!!!!!!

I take the nitrates back, I just looked directly down into the tube and it's darker than it looks straight on. It's around 40 ppm. I just did a water change yesterday. 50%

There is nothing decaying in the tank, nothing has been uprooted recently either.

I will be putting more floaters back in the tank there probably high because I removed them all last week I don't like the tank being covered were the light doesn't penetrate to the bottom

It may be associated with the stone. AFAIK stones in general are not compatible with shrimp tanks.

Do a water change with rodi water from your lfs this will bring your gh down as rodi usually has nothing in it.. As marine salt mixes have magnesium/calcium/strontium/ect .. So what your getting is just water you'll have to treat it with a ph buffer but should be really soft..

I'm not using marine salt though. I get my water from the dispenser at luckys 6.2 ph soft no gh or kh to it. When I re mineralize to 200 tds before a water change the gh is 4 and kh is 1.

Are you saying that you re-mineralize your RO water until its 200 tds? I hope not because that it way too much. Properly remineralized water (depending on which remineralizer is used) will be around 100 tds for 5gh

Gh extremely high!!!!

I was saying rodi wAter would dilute everything down including gh..


Rodi water is just water...untreated..marine keepers have to add salt and mix with powerhead for 24 hrs to cure it..

With salty shrimp gh+, it should be 110 tds at gh of 6~7, for me not sure what others get.

According to this website and several other I have spoken to that keep shrimp for many years they remineralize to a tds of 200 when doing water changes

This website sais crs a tds of 100-180 and neos 80-200
I keep my tds steady at around 180-200 above or below and adjust accordingly.
http://shrimpkeeping.com/water-params/

I use ss gh+ because it's ro water.

I have never had a gh or kh problem when remineralizing to a tds of 200. I do know that gh and tds have a close relationship and towel you the extent of what minerals and elements are in the water though. But when I have remineralized the water in previous occasions the gh has always stayed around 5-6 when my tds is at 200.
I do run keta peng granules in the filter as well to keep the water soft and a low ph but the rock and apparently the gh have been countering that effect. My substrate no longer buffers and I want to change it but I don't want to loose my shrimp from placing them in a temporary home to cycle the tank over with a new substrate.

that's weird, because i just tested on a 1 gallon bucket of rodi water. a 200 TDS for me has a gh of 13.

Ryuoh stone raises water hardness and pH. Take the stones out if you want to keep your pH lower and the hardness down.

http://www.adana-usa.com/index.php?m...roducts_id=272

There are stones that will not affect your water chemistry (e.g. Yamaya stone, etc.).

You can test any rock with a high degree of certainty by using the muriatic acid (which can be bought at a hardware store). Look up muriatic acid test for carbonates in rocks for more info.
