GH & KH Help

Recommended Posts

GotCrabs

I recently got a GH & KH Kit but it has no instructions inside, it's an API Kit.

 

Could someone explain to me how many drops I put in the 5ml cylinders and how I'll know when the water is right?

 

I emptied the water to about quarter of the tank and then added rainwater, tested pH and it's 6.6 and TDS is 58, so need to put the TDS up to 120.

 

Noob question I know, but thought I'd ask on here and look like a tool instead of surfing the web.

 

Thanks.

The GH & KH kit are titration tests. The way it works is to observe how many drops it takes for a colour change to happen.

 

So, just fill the test tubes to the 5mL mark and make sure to count how many drops it takes for the colour to change. Make sure to drop one by one and shake every drop for the mixture to mix evenly.

 

I have API GH & KH test too. For GH, the colour is from orange to green. For KH, the colour is from blue to yellow. The colour change will be very clear, it is easy to observe. The results in dGH/dKH is the number of drops added.

 

Good luck with your test!

Ok you just put one drop in at a time until it changes colour for Gh it goes green and kh it goes yellow.

 

For the TDS do you have something like Salty shrimp? it is usually better to put the salty shrimp in before you put it in the tank to raise the tds to what you want.

You may also notice kh is yellow? Straight away if your water is low kh < 1

Levels of Hardness (GH)

 

Degrees        Parts Per Million        Description
0 - 4 dH         0 - 70 ppm                   very soft
4 - 8 dH         70 - 140 ppm              soft
8 - 12 dH      140 - 210 ppm            medium hard
12 - 18 dH    210 - 320 ppm            fairly hard
18 - 30 dH    320 - 530 ppm            hard
Higher           > 530ppm                    Liquid rock (Lake Malawi and Los Angeles, CA)
 
 

I think the KH is considered low, and the GH is considered fairly hard.

Excellent, thanks Steffie.

 

How do I lower GH then? Is it possible?

Also, I have Boss Aquaria Mineral Powder, would that raise TDS levels?

I believe you want it between 4-6 for crystals but cherry's are fine up to 8 or so.

Well I would say use RO water if you had some but if your shrimp have been doing fine in those WP then I would just say leave it.

 

Maybe someone with more knowledge can help.

Does your local store sell distilled water? maybe thats the next best option? unless you tap water has lower gh? I dont think I am doing a good job of helping lol

No it won't raise the GH & only slightly raise the TDS, but not enough to be a concern. :thumbsu:

Yeah I can get distilled water, get massive bottles of it actually, would there be anything I'd need to add though to the water?

really and your GH is that high, what is the TDS in the rain water?

 

maybe test just the rain water for GH

      O.k rethink. If I use that Salty Shrimp GH/KH stuff. Can you recommend any good fertilisers I could use for the plants? I'm not dosing anything at the moment.

      Not going to lie, this is giving me a headache. Just want a nice planted tank with fish and shrimp. 🤨 At the moment it looks like it have to either pick 1 or the other. Would this be a solution. Use Seachems Equilibrium and KH products to bring my GH and KH up to 4, then use that Shrimp King Mineral Fluid Double, to bring the GH up to 6. That would make sure that there are at least some minerals for the shrimp.

      Hi there buddies wanted to show you pics of pipefishes I caught in the wild, Microphis brachyurus and Microphis cruentus. Unfortunately, I now exceed the limit quota of attachments on my profile. Will try to fix that issue ...

      My vote is for Endlers. Mine are the most fascinating (from a fish lovers point of view here) and cute fish in my tank, but I reckon they would be perfect for you, as mine are constantly picking on stuff! They’re the only fish who eat my dreaded snail eggs (on the glass and other surfaces) which I love! Plus you don’t need heaps. Males are small if you just want them for this. And you will be able to get them anywhere.   I have a school of 20 embers in my tank, but I rarely see them hunting in any manner, much less on surfaces.

      In case it helps I have looked up the figures of the 2 tanks with cherry shrimp in them and they are as follows, Main tank     PH7,, GH5, KH2, TDS 225 (mixed water) Betta tank  PH7.5, GH6, KH3, TDS 222 (tap water + mineraliser) They are fairly similar to each other but neither is really in the 'IDEAL' recommendation range of CHERRY shrimp ,so it confirms that cherry shrimp are more adaptable and can thrive even outside those 'IDEAL' parameters? I suppose neither are that far out but it just shows there is a bit less necessity to get everything 100%, though if you aim for perfect you will probably get better results all round? Simon
