First Sulawesi Cardinal Tank

Recommended Posts

KeenShrimp

Yep, I have to choose between buying shrimp stuff or a fancy camera and the shrimp always win- please excuse the photo quality.

This tank is now 2.5 months old: It's not pretty at all as I cannot cover bits with plants and am too worried about upsetting these guys to scape it. The ramshorns will be removed at some stage, but I am messing with the tank as little as possible.

I was very nervous about starting a Sulawesi tank as I read that they need stability. I wanted overfiltration, and as much of it that I could stuff in a small tank as I could. So I took a 29 litre Animates desktop tank and altered the filtration: I cut a 2cm x 1cm window where the filter intake slot was and covered it with nylon mesh and coral glue to increase water circulation (the solution does not look as classy as it is efficient). I also wanted something better than a sponge filter as my second filter: I bought an Acrylic corner filter: upon receiving it I noticed that the factory didn't even put intake slots in the filter, so it was just blowing bubbles and not circulating any water at all. I cut my own holes, rearranged the sponges so that shrimplets can't get sucked in. Then I stuffed that puppy with Eheim substratPro and a few other bits (yup, all I need now is a fake Nemo, suspended from fishing line to complete the plastic look :(, but it works like a charm and that water is crystal clear.

Pisces black inert quarts in the bottom. MarinePure filter media in the built-in filter. I have to thank very patient Chelsea @The Tech Den: I emailed her explaining that I wanted a reef shelf/base rock that I could prop up and grow algae on and have the shrimp hang upside down at the bottom- she emailed me photos and measurements and we found perfect rocks for cheap as chips! Next I harvested every algae type from 4 other tanks and stirred it into the water. 6 weeks later, I had lovely algae cover over the large rock. The corals in the photo are genuine coral skeletons.

I use Sulawesi 8.5 due to improved formulation, and now I am a sucker for boiling the salt solution mix on the stove for an hour when mixing my water, but the shrimp are looking very happy. If you have not used SaltyShrimp Sula 8.5 before: that stuff does not dissolve, no matter how much air you pump into a bucket it will be as white and cloudy as skim milk! I boil it on the stove, use 3 times the recommended amount, let it stabilize for a week with a heater and ensure that GH is 8 before it goes near the tank. The water is then crystal clear and the sediment has sunk to the bottom of the bucket.

The shrimp photo below are of Bonnie and Clyde. They went hiding when I took the insulating towels off the tank ( it's freezing in Canberra). The breeder of these beauties is @JPN07- how gorgeous are those blue dots on the body?

They get fed every 3 days with Shrimpy Daddy Sinewy cereal. Micro amounts of trace minerals/nutrients and probiotic solution is added every day as well as weekly minerals ( ShrimpyDaddy) and Vivace (ShrimpyDaddy).

I will be getting more Cardinals soon so that I can have an actual little colony.

Good work. I must be the only one I know that just dumps the Sulawesi minerals straight into tank lol Might explain my slow reproduction rate.

@NoGi, which salts are you using? 7.5 or 8.5? I bench-tested the 8.5 for various  dissolving options, and when I added it to the buckets without properly boiling it first, the GH-creep was all over the place, including TDS in the ones I had dissolve naturally for two weeks, and because SaltyShrimp is so darn hygroscopic, I don't measure it out by weight, so the only sure way of ensuring the Sulawesi replenished salt is stable at GH 8 that I found is the boiling method. The water is also crystal clear that you replenish with after it has been boiled and the sediment sinks to the bottom after a few days of heating....

I use Salty Shrimp Sulawesi Mineral 8.5. I generally grab a small plastic cup, put in required scoops, mix a little water from tank and pour in. Tanks goes freaky white and then all clear by next morning.

Almost always, I see fresh moults from my natives so something is working right I guess. My sulas, natives, snails and crabs don't seem to have an issue.

I don't measure GH so the creep you are seeing could be present in my tank too.

      No problem. Love helping others if I can. Report back in a week or so. You should test TDS every day around the same time, to keep a track of any changes.

      Sounds good Jay. Thanks a lot I appreciate all of you

      It sounds about right for GH6 (6 drops is roughly 120 TDS). Those GH test kits are not the most accurate. And RO water reading of 3 is not unreasonable. I don't know why you would have been reading 240TDS last week and now it's a 100 points lower. I would suggest, not changing water parameter with a water change for a week, then see where it is at. Change if it gets close to 200 (say around 180-190). Let's give the tank some stability by not changing anything for a while.

      I checked my TDS meter and it reads 3 on RO water and today my TDS in my tank is 133. I did a test with API and it took 6 drops so that's around 100 TDS.  I had 2 adolescents die overnight.  Should I only change water when it's over 200 TDS or should i continue with the 10% every week?  Thanks
