Howdy Shrimpers!

I've got some questions that I'm stumped with!

 

So I've set up this nano IQ5 aquarium for about 5 weeks ago and around week 3 I noticed the PH was at 6 when I tested it.

I've attached a photo of the tank (hopefully! First time uploading) in case anyone has an idea to what is dropping my PH. 

My PH test kit only shows up to 6 ph at the lowest so it may be even lower. 

1) Any idea what is dropping my PH from the photos? I have a feeling its the substrate or the stone inside but don't know what their names are...

 

To top it off, as I have been doing my routine tests, it looks as if the tank isn't cycled yet even though the 2nd tank I set up at the same time IS fully cycled. The 2nd tank has just some gravel and drift wood inside though. 


The results I got for the nano tank yesterday when I tested the water parameters were:

PH 6

Ammonia 1

Nitrite 0

Nitrate 0

Gh 3

KH 2

TDS 128ppm

I tested my tap water to figure out if there was something wrong with and my results were:

PH 6.8

Ammonia, Nitrite, Nitrate 0

GH 2

KH 1

TDS 57ppm

2) Is it even possible to have TDS of 57ppm out of the tap?

My TDS meter is a new HM Digital AP-1 with a 342 ppm calibrating solution.

Can anyone shed some light on this for me. I'm stumped :/

It could be the large piece of driftwood. Did you soak it or boil it before adding it to the tank?

You could try slowly raising the KH to 4ish. It will bring and keep the pH up.

And yes, TDS of 57 is possible. Mine is... 98 ppm right now and I'm on a well, so it's generally harder.

Especially possible if you are in Melbourne. And with all the rain lately.

If your tank isn't cycled properly, pH will continue to drop as part of the natural cycling process. 

 

When was your last water change?

 

I see you have fish in there already. So you can't do a massive water change. Try a 20% water change at least once a week with your tap water and dechlorinator.

Thanks jayc that's an exciting thought!

I've been doing 1 x 50% water change once a week but the first 2 or 3 weeks was twice a week water change.

I've also used pre cycled filter media in the tank from day 1 hoping to speed up the cycling but I think it's crashed or re started... Week 2-3 results were looking as if it skipped a stage and was cycling fast. I'll go to the aquarium where I purchased the substrate from today and ask them the question I think. I also use prime as a declorinator if that helps

Cheers Mr F - I did boil the driftwood before placing it in the tank twice over hoping that would help and reduce the tannins so I don't have a brown tank!

Also the fish seem to be doing ok... I expected and did have a couple deaths in week 1 or so and they have been steady for the last 3 or 4 weeks... 

Now I've got the idea of moving the cardinals out of the tank, replacing the gravel, placing them in the established tank and doing a fish less cycle / restart on the nano tank... hmmm

So the guy at the fish store suggested it's the driftwood breaking down that's lowering the ph but I believe it's also because the tank isn't cycled yet (for some reason?).

So I've removed the cardinal tetras and replaced the substrate with a dymax brand planting substrate. I'm going to cycle the tank before adding anything in it again. No cloudiness at all in the water from the new substrate which I didn't expect. Let's see how well the plants grow in it!

In other news, I've noticed saddles on most of my cherries which is exciting! I just don't know if I have any males :P

I'll do another water test in about a week and keep you posted!

My ph was 6.4 I then added a nice peice of driftwood and within 3 days my ph is at 6 or could even be lower as my test only goes to 6. My CRS seem to be doing fine though

Get a pH pen.

A cheap pH pen is still better than test kits.

I'm thinking about getting one jayc! Any recommendations?

Update: tank is still cycling which like mentioned would explain the low ph. I did a small water change yesterday and threw in a little more food to keep the Amonia up and now have to play the waiting game!

Has anyone heard of the iq5 before? It's the nano tank I'm cycling at the moment and purchased from coburg aquarium (I'm not sure if I can mention it and will remove the name if required).

It has some slots to overflow into the back compartment which holds a small filter.

I'm a little worried to add shrimp in it because of the possibility of shrimplets being sucked into the filter compartment even though it's only a small pump.

Does anyone have any ideas as to how to block it up so that doesn't happen?

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      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?

      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.
