Hey all,

Tank Info:
70 L (approx 20gal)
20 PRL shrimp (no deaths since put in the tank)
Lighting period 8 hours
heavily planted
Substrate ADA Amazonia Light
Filtration is a canister and two sponge filters
RO water remineralised with salty shrimp Gh+
Ammonia, Nitrate, Nitrite - tested and all good
GH - 7
KH - 0
PH - 6.4
TDS - 150

Writing this regarding my PRL shrimp. Recently purchase the API GH & KH test kit and did a test on my PRL tank. The results came back GH 7 and KH 1 (0). My GH result was alarming to me due to me talking to other PRL breeders and they all have their GH around 3-5. However, I searched it up and came across this website that says that bee shrimp need a GH over 5 to have sufficient minerals in the water for successful molting.
Website is SHIRAKURA - Information on successfully keeping and breeding bee shrimp
Just wondering if my GH is ok for my PRL shrimp and that it will not affect the breeding rate

cheers

Well if you are really worried about it, its easily solved with a 15% water change (1/7) with RO water. That would bring you down to GH 6. Make sure you top off with RO first before doing future water changes, that way your GH wont keep creeping up.

If you have no deaths, I wouldn't do any big radical changes chasing "ideal" numbers. The shirakura site you linked actually shows GH 7 as what the substrate they're selling gives when using GH 10 water, so I assume GH of 7 is ok for this strain. Or it wouldn't be part of the ad pitch

Are your shrimp breeding?

Are the offspring growing successfully to adults?


If you can answer yes to both, then don't change a thing.

If you can answer yes to the first, no to the second, then try changing parameters.

If the answer is no to both, then either you haven't had the shrimp long enough or conditions aren't right.

Awesome! Yeah just did a water change a few days ago and don’t want to do one again just to drop the GH down by one. Thank you for the advice

Well the shrimp are all growing up well but they are not breeding. I’ve only had them for 2.5 months so I will just give them more time. Thank you so much for your reply!
