My 7.5 gallon Penn Plax

Iíve decided to start a journal for my new tank so I can look back and learn from it in the future. This is my second tank, but the first one running a fishless cycle with ammonia and cycled media from my other tank. So far itís not going well. I was all excited because two days after I started my tank I already had reduced ammonia, high nitrites and high nitrates. I figured I was almost set. The next day the nitrites and nitrates were off the charts so I did a 50% water change. Ever since then I cycle seems to have died and Iím starting from scratch. I have no idea what I did to wreck it. The only thing I can think of is maybe I forgot to put prime in my tap water. Disappointing anyway.

Last night I remembered I had some Prodibio Start Up vials that I planned to use on the 12 gallon long I have sitting gathering dust. I have big plans for that tank that will require more money than I have currently so it will remain sitting for the time being, so I decided to use the Start Up on this tank. Weíll see how it does over the next few days/weeks now.

Penn Plax 7.5 gallon


Fluval Nano Aqualife LED on 2:30pm to 11:30pm daily Ė it seems way too bright, at least compared to the 16Ē Fugeray I have on my Spec V.


Zoo Med 501
Biohome Biogravel

Temperature Control

Hydor Theo 50W
Finnex Max-300 Digital Aquarium Heater Controller




Fluval Stratum
Seachem Flourite Dark cap


Seachem Flourish Root Tabs. Far more than recommended because I was dumb and didnít read the package. Maybe this is what killed the cycle? I donít know, Iím grasping at straws.


Rotala Indica so far. Iím planning to add java fern, ludwigia mini red and some buces and mosses, maybe some red root floaters. Iím also thinking of trying an HC carpet. Iím going to wait until itís done cycling before adding anything other than the rotala though. Iíll update as I add.


For fish Iím thinking red neon blue-eyes and pygmy cories.
I want shrimp, but the only shrimp I plan on adding are amanos for the foreseeable future. I have terrible luck with shrimp other than amanos.
A nerite snail or two plus I have lots of red ramshorns and MTS in my other tank so Iíll add a few of each of those as well.

Bump: So this was how things looked on the 20th. My water tests showed the cycle was well on its way and I was having a bacteria bloom.
