Strange result with Salty Shrimp GH KH

Hi All,

I'm really getting a strange result with Saltyshrimp GH KH mixed with rainwater from my farm.

I put 20L in a food grade plastic jerry can and add 2 level spoons as per the instructions, then fill with rainwater.

The rainwater is absolutely pristine, and stored in modern plastic storage tanks (45000L) that are less than 2 years old. Tests at 5.6PH, 5ppm. If you google it, you'll see pure rainwater is meant to be slightly acid due to some sort of reaction as it falls or something.

When I add the salty shrimp, the ph runs straight up to 8.4ph and about 130ppm.

Thing is, if I add only one scoop (half dose) it still goes to 8.4ph and 70ppm.

I've calibrated my meter using the proper solution, and storage solution etc. 

I also test with an ADI kit as a back up.

Seems weird....shouldn't it be buffering to 7.5ph?

Can anyone offer some advice on this?

anyone able to answer this? i was kinda interested why, but no one has replyed yet. maybe @jayc or @Disciple can help

i dont use this myself, but i know mine lowers the ph, so for yours to make it higher is werid. but you use the GH/KH mixture. re check your rain water ph maybe

Sounds about right to me.

rawprawn is using "Salty Shrimp Shrimp mineral GH/KH+"

Don't confuse this with "Salty Shrimp Bee shrimp mineral GH+".

I've used it's full name to show that there is a difference in the two.

 

Salty Shrimp Shrimp mineral GH/KH+ contains what I believe is, Sodium bicarbonate, which raises KH and also pH. The Calcium Chloride and Magnesium Sulphate in SS will raise GH. Oops did I just give away SS's secret recipe. :crazy:

How much it raises pH, I don't know since I don't use this product.

However, it would make sense that the product could raise pH up to 8.4. When you add this to a mature tank with a mature filter, the natural process of breaking down ammonia by the bacteria will cause pH to drop. So a starting pH of 8.4 can drop & stabilise to somewhere around 7.something over a couple of days.

Not sure where I got the idea of 7.5ph....on the internet somewhere.

Yes, it's the GH KH, specifically for cherries.

While it would mean that both my meter and API kit were wrong in the same way, which I would have thought unlikely, I've ordered new calibration solution and will take samples down to the LFS (breeds a lot of shrimp himself) and get it tested there as well.

I'm really considering just putting the rainwater in a container, adding the prescribed amount of SS and stopping looking at all these things.

They are cherries after all, none are dying and they look happy enough.

If you add Epson salt and calcium chloride (ratio 1:4) that should raise the GH w/o affecting KH or PH.  Calcium chloride used in spas, swim pools, ice melter.  After getting GH where you want it chech the TDS.  If you want to raise PH and buffer add baking soda, however this will also affect the 1:4  mg to CA ratio.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Shrimp and meds containing gentian violet

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?
