19 Litre Fluval Spec
« on: March 04, 2021, 01:34:52 am »
Hi folks, I thought I'd capture some details of the new little tank (my smallest yet) that I hope to turn into a home for some shrimp.
 The tank was first filled 21st February 2021. Plants were added on about 26th.
 
 So far this consists of the following:
 
 
  • Tank: Fluval Spec 19
  • Heater: Interpet Nano 25W
  • Substrate: Fluval Plant and Shrimp Stratum
  • Substrate: Pettex Roman Aquatic Gravel
  • Plants:
    • Cryptocoryne parva
    • Limnophila sessiliflora “Ambulia”
    • Anubias nana
    • Christmas moss
    • Riccia
    • Hygrophila polysperma

     Cycling is currently under-way. I think it's going okay - I put in a glug of Ammonia on 25th Feb (it really doesn't take a lot in a tank this small!) to get it up to about 4ppm, and it's now (4th Mar) down to pretty much zero. I have been adding Fluval Cycle, and a tiny bit of Fluval Grow+ went in to give the plants something to chomp on.
     
     
    • Ammonia: currently <0.1ppm
    • Nitrite: off the chart >5ppm
    • Nitrate: off the chart >80ppm
    • pH: steady at about 7.6
    • Temperature: about 25°C
    • Hardness: 15.23dKH (272mg/l CaCO3, from official test results, not my own)
    Should I bump the Ammonia back up to 1ppm and see what happens to it, or wait until the Nitrites come back into a measurable range?
     

    • 22nd Feb - First fill. Stratum made the tank look like it was filled with bad coffee​
    • 24th Feb - Replaced most of the water to remove the bulk of the floating particulates​
    • 25th Feb - Added 1ml of 9.5% ammonia (up to ~4ppm)​
    • 1st Mar - Added 2L of fresh water to bring to full. Added ½ml of plant ferts, and ½ml of the bacteria​
    • 2nd Mar - Added another ½ml of the bacteria​
    • 3rd Mar - 7L water change. Signs of possible algae growth - almost invisible strands on the rocks and tinting on the white sand. Light was probably an error, so turned off now.​
