hi everyone last night i added some gravel to my cycling 10 gallon so the bacteria would have another place to grow however today i tested the ph on the tank and it is 7.4 its usually 7, i checked that the gravel was inert what could be causing this?

Could u post a pic of the name and packaging? It might be worth it to check yourself if it is truly inert.

Most other fish will prefer a neutral pH, though, so it might be wise to change it while it’s less of a hassle. Ur choice tho, it could still work out fine.

For the meantime, though, the guppies will like that.

Never trust the shop keeper with questions like that. 

Some gravels are indeed inert. But the shop keeper automatically associates it to ALL gravels as the same. 

Unfortunately, not all gravels are the same or come from the same source. So moral of the story, you cannot assume all gravels are inert unless it is tested to be inert. Even gravels from the same brand can be sourced from different locations, and have very different effects on water parameters. 

At least you have grounds for returning the product now. The shop keeper told you incorrect info.

Apparently shrimp also like higher ph.

How would I go about removing it?

Neos like neutral, and caridinas most definitely will not like a higher ph. If u want i can come over to help remove it - I have a bit of experience with that. I drained the tank - turned the filter and heater off before, of course - and scooped it out with my hands, and at the end I used a scoop, like from a brush-and-shovel sort of thing. U would want to keep your filter and media in a bucket with aquarium water. 

And as jayc mentioned previously, you have clear grounds for returning the gravel. Get something that is clearly packaged, that you can look up when ur there.

cherry shrimp and the fish you plan to get will be fine with that figure so I would just carry on! Caridina shrimps won't like it as crabby says but as far as what you have posted I assume you would be getting the easier/stronger cherry shrimp if you do get shrimp! My cherries have lived happily enough in PH 7.5 for years with the tetra fish.

Which tetras do you keep with the red cherry shrimp and how hard is your water? I’m also thinking about Corydoras and blue velvet shrimp.

I keep ember tetras and neon tetras currently. I love endler guppies but they don't do well in that tank as they are too adventurous and end up getting stuck under/behind things so have given up on them, but they are/were my fave! Tetras don't seem the be as adventurous and stay mainly mid water level. I have kept the green neon tetras in the past as well in that tank.

I also have another tank with a fighter that has red cherry shrimps, that also has PH 7.5 - they were meant for him as food but he just watches them and they have now bred............

My tanks are too densely planted to have corydora but anyway they aren't really 'my thing', but they are very popular and a friend has lots in their tanks.

If you are planning on the dark blue (velvet) shrimps they won't probably show up very well if the gravel you got was black? You need a contast, bright colour shrimp on dark substrate and dark shrimp on sand/light substrate so give that some thought before you get too far into setting up the tank in preparation?

Yeah nothings set in stone thanks for the ideas I’m also thinking about setting up my 6 gallon for betta and shrimp so good to know that it might not eat the shrimp.

There is an element of risk with the betta as I have had one that ate shrimps in the past so it may or may not work out?

If the substrate you got is black then I would consider bloody mary red cherry shrimps and you could mix in with some tangerine tigers as they don't interbreed and both are easy to keep and robust and can live in the same water parameters?

Yeah i dont reallly mind if the betta end up eating the shrimp as i can move them to my 10 gallon. Also whats the difference between RCS and the bloody mary variety?

Bloody Mary are often thought to just be a higher grade, but I believe they actually originate from a different wild shrimp than cherries, although they are still neocaridina davidi. This can be seen below.

Bloody Mary are a much nicer looking shrimp, though, with a deeper red colour. 
Here’s a great video that explains it:

As crabby states, they are just a better colour than standard red cherry, and that will show them up better on black substrate!

You can of course do what I did which was to not buy any shrimp for the betta tank, but just transfer any unwanted badly coloured shrimp (culls) to the betta tank as they come up in the 10 gallon. This way if the betta does eat them then you won't be too bothered, but also as the colour isn't as good he may not be interested in them, like mine!

That’s a good idea thanks I’ll keep it in mind when stocking.

I would test it out with ghost shrimp first, or red cherry culls like Simon said. If they work then you could add a more intense Bloody Mary or painted fire red shrimp.

Especially in terms of price - ghosts and red culls are $1 max, whereas anything nice is $8 each at least.

Right okay I’m not starting the 5 gallon for a while probably after summer but thanks for the advice.

      Um, because I’m all over the place I thought it pertinent to mention I’ve slowly lowered my GH to 5-6 over the last week and a half, or so. Slowly, but these shell issues existed long before adjusting the water parameters. I suppose it’s possible this could have finished off the injured shrimp, however, the parameters are, from what I can gather, a little more superior at this time. The GH was lowered by monitoring my TDS drop closely. I dropped the TDS by around 2 points daily. At this point, I’m sitting at:   PH: 6.2 GH:5-6( during testing, the color teeters between 5-6 drops for a change) KH:0 TDS:140 Temp: 72f   So, now that I’ve completely sworn off of fertilizers, I haven’t seen any increase or decrease in TDS / GH without my own manipulation. Second and third generation of shrimplettes are doing well, and aren’t showing any signs of discoloration. Another mama likely soon to drop as her eggs have easily visible eyes.

      I apologize for being unclear. I had ordered one before asking more specific questions. So I simply located a different one and order that( the one you green lighted), while also canceling the less desirable one. Also, the one you told me to buy, was considerably cheaper, while retaining the same no additive ingredient list.   No signs that the oregano leaves were touched this AM, but, there were multiple shrimp surrounding them, while several were perched on them. I’m not sure how much they need to ingest to really help, but hopefully the sampled a little bit overnight. Now, my problem is locating a food that they will attack, to place into the tank. Would it be possible to mix some BacterAE/ Shrimp Fit powder into oregano oil water? They seem to feed on that when it’s added to the tank.... otherwise, I’ll use some rephasy, newt made, with oregano oil water added.... or something similar.

      In relation to the PH, what is too low? Because several people in other groups act shocked at my PH at 6.1-6.2. The substrate is ADA and has always buffered to that range. Even the Fluval Stratum I used in the smaller 5 gallon buffered similarly.
    • sdlTBfanUK
      You are indeed correct in that I didn't see a cycle as such, I only had nitrates of 25 to start (cooked prawn) and that dropped but also as you say the PH was very low, below 6 so a proper cycle may not have happened - well spotted, I had forgotten about that. I set the tank up in June so if it isn't cycled by now though I guess it never will be? Incidentally I have only got the Ph up to 6 (recently) by putting a bit of the old rock back temporarily, and possibly that caused the tank to cycle or something??? I have thus far got 4L of RO water and hope to get more done so I can do a approx 50% water change at the weekend. You make a lot of valid points and thanks for giving me more to go on, maybe the plants aren't as green in this tank because of the different parameters and the substrate isn't as bad as it appears? The other tanks have Ph 7.5 so quite different! I like your point one and that seems to be how most people think in the modern world, but I am 100% sure it is my fault one way or other, I am old school! I am however physically restricted so it isn't anything I can do anything about! Got friends coming on sunday so if I get the water ready they can lug the buckets of water around................. I will get some rubber gloves anyway as that means I can rule that out, and give me peace of mind for the future that I won't accidentally contaminate the water by mistake? I have been using a lot of cleaning products (scrubbing floors) around xmas which makes me think I may have contaminated the tank without realising??? Simon

      Just to update that I went back to my normal, very low dose of fertilizer, but the Ludwigia are still dying, from the bottom up.  The tips are green and growing, but the bottom parts are rotting away.  So far, I can only think of two possible reasons: 1) I have been feeding my shrimp less, so maybe they aren't making enough ammonia and nitrates for the plants 2) About 2 months ago, I changed the lighting so that it was a complete blackout at night and only 7 hours of medium light a day.  This did a great job of getting rid of algae that was growing on the plants, but maybe now I need more light again?
