60 litre Iwagumi. CO2, ferts and metal halide.

Well where to start? This tank is my first planted and has been setup about 2 months. In that time I've done almost everything wrong at least once, but have learnt hard by my mistakes.

Luckily I was keeping a journal, to some degree, at my website Dwarf Shrimp but here's a basic rundown.

  • Elite 60 litre tank and stand (paid 20)
  • lighting unit (150 watt metal halide, suspended 30 cm from water surface) (paid 23)
  • cheapo compressed co2 system with diffuser (paid 20)
  • cheap heater (free)
  • Eheim powerhead with sponge attachment.
  • Oliver Knott Active substrate (similar to ADA ammazonia II) at a depth of 2" with sand underneath. (probably 30 worth)

Now to start back in February i had a large rock which I'd cleverly covered in Marimo, doesn't it look nice and fluffy?

I add some Dwarf Hairgrass as a background plant.


I get hold of some HC Cuba, great!


Trouble strikes! Marimo, is in fact Clado! Oh no I've just dosed my tank with the worst algae there is.

I treat with h2o2 and Excel, 90% is destroyed very quickly, the last 10% takes forever to obliterate.

I get all my Co2 and ferts wrong like a newbie and leave the 150W MH on way too long. Here comes algae:


I persevere, i keep removing the algae i find, and any java moss that appears to have infested the rock. I get the ferts nailed (thanks to here), and begin dosing with Potassium Phosphate and Potassium Nitrate.

The HC Cuba takes hold and spreads well. The Hair Grass grows aggressively, even moreso with weekly trimming, it fills in well.


I'm still not content though, that rock it's the cause of all these issues. I go to the LFS looking for some driftwood to replace it, but 3 lovely pieces of Jaderock catch my eye.

I immediately could see an arrangement in my head so quickly rushed home to set it up.

Obviously a bit of a bare patch now, but looking good. Algae is down to almost zero levels and the shrimp are thriving!


I love the greenness and am looking forward to it being fully covered, along with the crystalised green in the rock it pops, it almost certainly has a kryptonite feel and so i christen the tank "Krypton".

And so that's today, and I've caught up, 8 weeks over 1 post. For more info on what I'm doing visit the site in my sig, I go into more detail there.

It's a fun hobby, and I like to think that by the end of this process I'll know what I'm doing. Note to all, never split open a Marimo ball!
