No I mean like cold from the refrigerator cold. 5 DegC.

 

Hey @jayc after do i mix all of it in 5Degc or only the CaCO3. Or should i mix the CaCO3 in cold and let it become room temp and mix the rest in?

Here is my formula for re-mineralising RO or Rain water:   Powdered compound Grams needed: Calcium Sulphate CaSO4 Heptahydrate (so it dissolves easily

It pays to read the threads on SKFA.

There's your problem. And that IS weird.   I haven't measured it like that, so I wouldn't know. I add my 106gm mix into a bottle and add 500ml water. So I turn the mix into a liquid.

@jayc i managed to mix all of the ingredients together but its not full dissolved, where i drew the blue line is where all of the undissolved parts are, im using rain water with a ph of 6.5, im afraid when i mix it in the rain water the mix will not dissolve.remine.thumb.jpg.f4a06241fb0108a87cfc5a439b80f3ed.jpg

Don't worry. This is cloudy colour is normal and some undissolved calcium is to be expected.

Just give it the bottle a shake before use. And when you add the desired amount to your change water, you will notice the mix will dissolve / dissappear the rest of the way.

Okay I did that and after some times the water cleared up, could it be the remainder of it just sank to the bottom? Also the tds is 156 will it continue rising because the rest will dissolve with longer time maybe?

Only a very small amount might sink to the bottom, but it should dissolve rather quickly in tank water. 

The TDS should not rise too much more than 156.

Okay thanks jay, all of them even the babies look to have settled in well. I will update the progress so everyone will have feedback on your diy. But so far it looks good, thank you once again jay.

      Hi Crabby, I’ve been popping in and out quite often and answered a few questions here and there .  Im glad to have been of so assistance to fellow shrimp keepers over the years.  It’s a bit sad to see the forum so quiet. We were a very active and friendly bunch over the years. Helping each other out, giving away shrimp to new members who showed interest. Even playing games between us and generally having fun while learning about our new hobby. As to my tank the reason I queried about the spike of ammonia is mainly because if you play with substrate , move it around etc you can cause a small spike. As my substrate had been outside for quite some time I fully expected it to take a week or so to go through a mini cycle. I’m pleasantly surprised that it still isn’t showing any change just the tiniest bit of nitrate so tomorrow i will catch out 20 culls I have in my pond outside and see how they go. I need a reasonable number because it’s a big tank - if I only put 1 or 2 in I might never see them. I’m wanting to put all my black pinto, galaxy and Taitibees into the tank plus some Blue Bolts and Steel Blues. I will also put my Bloody Mary’s in for a contrasting colour. I only have 3 tanks now so it’s a bit hard to do proper selective breeding but as all my shrimp are hybrids it doesn’t really matter about mixing them. That leaves a tank for my Red pintos and Taitibees and a tank for fancy Tiger patterns and Blue Diamonds. That should keep me happy again.🥰

      Hi Ineke! I must say, I was pretty surprised to see a post from you, it’s always pretty interesting to see a past member come back to the forum. Some of your posts were really helpful to me when I was getting started with shrimp, so thanks!   I think I would personally wait a week to be sure, but to be honest, I can’t see any reason for an ammonia spike. If the substrate has already run for 4 months, and you have 4 fully cycled filters, I reckon you should be fine. Definitely go culls first though.

      I uderstand your concern, it is concerning! You are probably just going to have to ride this out, as JayC, add another filter and bacteria, the bacteria you will just have to buy what the shop has and give that ago? Do as thorough vac as you can, moving things out of the way where you can. Keep up with water changes as well as that will reduce the ammonia etc, but add new water slowly. Simon

      Thanks Simon . I just needed someone else’s thoughts. I will pop a few culls in over the weekend if the ammonia hasn’t spiked. Better to be over cautious than sorry. It just didn’t seem right that there was no spike but I guess 2 large canisters full of bacteria are a big help too. I will let you know how the culls go after the weekend.  As you say sometimes things just go right but not very often when you have TB type shrimp involved 😳 No not really I’ve been very lucky over the years with no actual disasters with my shrimp.

      I would thnk everything is ok as the sustrate was used and passed the point it may cause a spike, but just check it for a week (occassionally ammonia/nitrite/nitrate, you could leave it for the week but I would prefer the extra peace of mind you will have from more frequent testing for this week) and try some culls now to be on the safe side! Using the old water will have helped, undoubtedly! There doesn't sound like anything mentioned would cause anything other than what you have seen, but I understand your concern, rarely does everything go so well in this hobby, but with your years of experience and from your post all looks great - I will however keep my fingers crossed................ It is always great to have past members return and hear how it is going? I have read many of your old posts with interest. Simon
