ADA Mini M scraps tank

Past tank as it stood before being torn down:


Most of the stuff on this tank is over 4 years old from my last run. Only new items are the filter, fertilizer and soil. I plan to add some caridina shrimp after cycling the tank.

Specs:
Tank - ADA Mini M
Light - Finnex (white + red LEDs)
Filtration - Aquaclear 20G HOB
CO2 - Aquatek Mini Paintball Regulator+Solenoid
Fertilizer - Tropica Specalised
Soil - ADA Amazonia

Dry started for about 3 months, sprayed once every couple of days and left covered.





Filled tank and immediately started CO2.




Added a few plants.




Tank as of 3 minutes ago. The rocks were from my last run and appear to have regrown fissidens on them despite being dry for 4 years.




Planning to trim the carpet soon and add a few plants as I decide which direction to go with this..

I'm liking the selection of plants so far. What is that plant in the last picture growing in the little rock nook?

Great question, I don't actually know..

Some new pics and plant additions. Added staurogyne porto velho and AR mini. Also added an amano and a few fire reds to test water stability for inverts.

Really like this tank! Nice work, will be fun to watch it fill in!

Thanks guys, appreciate the kind words

Side shot to show the progress. Everything has rooted very well and now I'm on the hunt for some bkk and blue bolts.

Beautiful tank you got there. However, you might want to steer away from caridina shrimp in this particular tank. The soft water that is required to raise these shrimps would eat away at that seiryu stone. It will raise both GH and KH. These particular shrimp need soft water that stays consistent. Most of us that keep these shrimp don't want any KH in the water. This is why we use remineralized RO/DI water and buffering substrate. Keeping a low KH will keep pH in the lower ranges when using buffering substrates. This is not a good idea, especially when injecting CO2 with shrimp in there. The constant pH swings from carbonic acid will be detrimental to them. They don't like any swing in parameters whether it be pH, GH or temperature. They prefer water temperature no higher than 74 degrees (68-72 being optimal for taiwan bees like RKK/BKK and BB). Water changes should be kept to a minimal as well (not good for EI dosing) and should it be dripped in to avoid sudden change.

I'm sorry if I discouraged you but you'll want to make some changes or even setup another tank if you plan to keep these shrimp, that is, if you care about the well being of them. Being as they generally start at $10 a shrimp, it could be a very expensive lesson to learn depending on how many you purchase. Take it from someone who has killed numerous taiwan bees in the past from "simple" oversights.

This is terrific advice. I've actually kept and maintained a very steady colony of SS/SSS+ CRS in my past tanks and have learned many of the same lessons you've voiced above. These rocks are recycled and were used in my old scapes. They have worked well with high grade CRS and CO2 injection. I water change 20% every 3 days and am lucky enough to have tap water with a TDS of 40 so I haven't had to invest in a RO/DI unit just yet. I use a liquid pump fertilizer called Tropica Specialised and use much less than the recommended dose. I dose about 20% their recommended amount. However, that doesn't mean that my tank won't be susceptible to swings in pH and hardness that could be detrimental to shrimp. You've given me something to think about...

CRS can handle a bit harder waters than TBs but if you haven't noticed any raise in GH/KH in the past, maybe you'll be fine with those stones. Where is your pH/KH/GH right now?

You can use CO2 in a TB tank because I've done it. I kept a steady but low flow rate going 24/7. This way I kept pH fluctuations under control. I aimed for around 15 ppm. I did this for a couple months before removing, just to help plants get started. Strangely enough, I had no berries during this time. A week after I stopped I noticed a few BKK had become berried. Not sure if it was increased CO2 levels or what. The shrimp seemed healthy enough with diffuser running, some even liked to play in the CO2 mist. I constantly saw shrimp with micro bubbles attached to them, like they were pearling. haha

needed to wait a couple of days for my GH and KH test kit to come in. API master kits don't include them anymore

based on the test conversion chart, it's at about 125ppm for both GH and KH. GH is slightly lower. pH is 6.5-6.8ish

Ok, your GH is fine for shrimp molting (assuming proper cal/mag ratio) but your KH is quite high. It won't take long to exhaust the buffering effects of that substrate. Once that happens, your pH will steadily rise.

Are you using R/O water or tap?

Currently using tap water. The GH/KH of my tap water is about 65ppm

So the rocks are leeching into your water after all. That's going to be an issue because you don't want to have to do large water changes to keep carbonates and minerals in check. It causes the shrimp a great deal of stress when parameters swing all over the place. I wouldn't add CRS to that tank, let alone taiwan bees.

That's good advice. Thanks for the insight and analysis!
