I've got a tank that's been running for about 4 months with a few occupants.

I was wondering if I could add a substrate (cal aqua labs black earth fine) via a cup, scoop by scoop.

I know black doesn't have much of a cycle so I thought it could've pretty safe.

Feedback appreciated

Thanks

When it first meets water the substrate sometimes floats for a bit due to trapped air, if possible I'd probably recommend at least lowering the waterline greatly and keeping the inhabitants in some of the removed water while it all gets done.
The less the substrate gets disturbed while in water the better anyway as it can cause a bit more of an ammonia spike, Black Earth does seem to release less ammonia then ADA and benibachi though

      Good video by Chris Lukhaup!

      One interesting thing he mentioned was "Bacteria pressure", which I guess just means number of bacteria around.  Yet I see all these other videos from shrimpkeepers bragging about how much bacteria their filtering system holds. Also interesting is no mention of using anti-biotics to treat bacterial infection.  I think that has fallen out of favor recently.

      Finally set up the 30L Shrimp Tank

      By sdlTBfanUK · Posted

      It has been a few weeks now and I have done a couple of large water changes. I tested the water parameters this morning, GH6 and KH2, TDS 140 and PH 7.5. Obviously the PH is off but there isn't anything in the tank that should cause the PH to rise to this figure so I will just run the tank for another month with 10% weekly water changes (probably just with RO water) and see where we are at that point. The RO water tests at PH6, and the KH and GH in the tank could come down as they are at the upper limits for Caridina shrimps! There are only about 10 very small snails in there at this point, but they seem to be doing well enough.

      Pure Red Line (PRL) Shrimps Western Australia seller

      By sdlTBfanUK · Posted

      I believe these to be very rare in Australia so you may even consider making it a longer term plan and produce your own by starting with the best CRS you can get as that is where the pure lines started! Depends how patient and interested in the project you are, but would save money as well? If I recall correctly it takes from 8 generations of selective breeding? They sell them at micro aquatic shop but do not ship to Western Australia, but that means they are available in Australia. https://microaquaticshop.com.au/products/pure-red-line-grade-ss-shrimp Good luck and just maybe smeone on here may point you in the right direction or be able to supply you with some.
