I usually expect to lose 10-20% in the first month from delivery/acclimating etc and we get next day delivery here in UK, so I would have expected a few more with the delay you had in delivery.
Fabulous that you have some happy mumma's and can soon make up for those losses! Expect a week of not seeing the new born shrimp though as they will be tiny, hiding and clear to start with.
well hard to say for certain but i think i lost about 10 total, had two molts in the shipping bag ... bag water had a tds of 85, in the one bag. these are neos. The other bag was a nice 225tds.
Update i have been seeing more and more berried girls. Tonight at feeding i counted 7 girls happily flapping tails full of eggs.
Hard to be patient waiting weeks for babies, seems like the first berried girl was about 2 weeks ago. Soon be a shrimp explosion.
All good! Test kit is in the mail and the tank hasnt even been built yet so just trying to plan it all out ahead of time. I bought the zero water filter and 2 extra cartridges and only plan to use it in emergencies ( unless the tank water tests really poorly) so it should last for a while. Thanks again for your help
With that filter you get the equivalent of RO water so it will be TDS 000, GH 0, KH 0, therefore you will need to add minerals to the water using GH/KH+ for the shrimps. The products will be premixed to offer the ideal balance of these 3 parameters so you only need to use the TDS meter to mix/measure the water to the level you want, so it will be really easy. I recommend getting a GH and a KH testing kit though so you can test the tank maybe once a month etc as there may be other things in the tank altering them slowly over time! It is still a good idea to know what theparameters of the source water(s) are as well?
This water filter will go a long time at TDS 000, then it will creep up but by the time it gets to TDS 006 it will go up almost every litre so you need to watch for that. Mine does about 80 litres at 000, then 10 litres at 001, then 5 litres at 002, then about every litre it goes up! They say to change the filter at 006! If your tank of rainwater (or even tap water) starts off with a low TDS of coarse the filter could last A LOT longer!
Ok thanks all, sdlTBfanUK I ended up buying the zero water 23 cup filter with the free TDS meter. I will test my watertank water and hopefully be using this (at the moment we only really use this on the garden), but now I have an emergency source of water for the aquarium in case we have an extended dry period. I got a couple of extra filters so this should do fine for me in an emergency. Maybe when we renovate the kitchen at some time in the future I will look into a legit RO system.
Thanks for all of your help team!
