Wow that looks like super healthy plants.
Beautiful! Great depth for a 55! Nice setup details too. Were the supports for the light fixture purchased or DIY? That is really cool.
Was the growth really that easy or did you just omit the hard parts? Any battles with algae or things you would do differently?
Keep up the good work!
Light supports are DIY or as i call it hand fabricated.
As with all aquariums they have rough days! I just changed the t5 light bulbs after 1 year of use and that alone caused a small bacteria bloom. Nothing big just something you have to help it through.
As for algae, this aquarium has very little, and I have never had a problem with it.
Listed in the details above, are the only changes I would make.
1) ph controlled c02 dosing
2) I would recommend the use of r.o. water for top off and re-mineralized r.o. water for weekly changes.
I didnt do this because I wanted to keep it simple to show and inspire others that this can be done with normal off the shelf equipment, materials and of course Colorado tap water
Hope the info helped!
