API KH test question

Recommended Posts

torface

Apologies if this has been asked before!

I have an API GH/KH test kit... it says that to measure the KH, the water must turn from blue to yellow. However my water doesn't even turn blue to begin with, its yellow from the first drop (but very pale). I read elsewhere that this means the water is extremely soft. Is this right? If so, do I need to RAISE the KH?

GH is 3... Is this too low too?

I hope i'm doing it right!

It depends on what type of shrimp you have? :encouragement:

Yellow cherries and Darwin red noses at the moment! But hoping to venture in to the world of CRS in the not too distant future! :)

Firstly, ensure you shake the bottle. Low KH for CRS is ideal (0-1), with GH at 4. You can raise KH by adding bicarb soda, but this will raise you PH as well. Try sprinkling some bicarb soda in your test tube to visually see the colour chnage, so that you know what your looking for/seeing. You can increase GH by adding Calcium, GH Booster, coral chips etc.... But all this depends on what shrimps you intend keeping. What soil is in your tank ATM .

Thanks BlueBolts.

I need to re test as I haven't done it in a while. The cherries are doing fine though.

Substrate is ADA Amazonia. PH is steady at 6.4ish.

Ok, just did a re test. KH is definitely 0. It's yellow from the first drop. I added bicarb as suggested and saw the blue, but i must have put too much in and couldn't get it to turn yellow again haha

GH is definitely 3

But I guess all this is probably irrelevant cos i'm going over to RO and salty shrimp soon :)

Your GH is a little high for CRS, it should be around 4-6 :encouragement:

Is it because high TDS isnt it? I have 11 dead in 3 days and I am changing water 20% everyday since yesterday

Could be a combination of high TDS & GH,I personally wouldn't do so much water at a time, maybe 5-10% per day :encouragement:

Thx again Squiggle. I gonna change to 5-10%. It's really sad when seeing these crs dying...

My 3ft tank might be ready this week. U reckon that I should move them to 3ft tank?

I'd just concentrate on getting this tank right & stop the shrimp dying, then you can shift your attention to the 3ft tank & get the WP in that tank the same as this one so you can move them later if you want, but get this one right so you have less to worry about :encouragement:

I think so, it's better to move from the old tank to the new one, but ammonia still between 0.25-0.5, so I wont move them yet.

And some of them are pregnant, better to leave them in the old tank? I afraid that they gonna sock while moving

The shell building up to hard for them to molting for long time then they......are dying. Got 1 more dead this morning, everything's ok until now. Hopyfully no more dead from tmr

A lot of dead in my old tank since last weekend. I changed water 10% each day but TDS keep increasing after a night.

This morning I check tds 361,gh 6 (which is decrease from 10). Change water from morning and check again in the afternoon TDS is 260 and it increase to 300 atm.

Currently, my new tank setup have:

NItrate: 0

Nitrite: 0

ammonia: ~0.25

ph 6.4-6.6

Kh 1

GH 3

TDS: 70

temp: 23 (which is the same as old tank)

Should I move these shrimp from old tank to the new tank? (I take tape water for both tanks)

If u slowly acclimatize them to that tank then it should be good,

I was battling high TDS/gh before and one thing I did do was give my canister a rinse with the tank water and they seem to have helped the TDS rising. Coincidence or not I don't know? Maybe worth a try?

I don't like the fact that you have slight Ammonia and no Nitrates, doesn't sound like your filter is mature?

I dont know why. Both of my tank have the same WP, except TDS,GH and ammonia. Anything wrong with my system? Cheers

      Traps don't work on hydra. Even with planaria, it is slow and it doesn't catch them all.

      Very wise as once they start breeding your population may sky rocket anyway, as they have with the CBS! I'm sure you should get some really nice surprises/colours when they start cross breeding too! Simon

      I will stick with the present shrimps, give it another month or so before I add some more shrimps.

      More fantastic pictures love the blue shadow panda and the 2 red pinto galaxy. Great to hear all is going so well! If you have a lot of CBS then they will breed when they are old enough so losing the 'mother' isn't too bad at this stage and they only love max 2 years anyway. Glad you still have 2 blue bolts as well - those will probably be my next purchase when they are in stock? The putting spinach in my tank has brought a few of my shrimps out but bizarrely they aren't touching the actual spinach? Seen 2 black and 3 red (of the 8 total I bought) so far today? Simon

      update my new tank is becoming stable, the shrinps are growing, I have seen many of the shrimps shread it's shell.   My old tank is infested with black CRS, but the mother had just died yesterday, I still have two blue bolts and a few CRS.
