Day 2.5/3:
After filling up the tank with tap water, I was naive to think that my heater would increase the temperature in the tank relatively fast, I was wrong. hour went into the hours. At last, I gave up waiting and went and did a 25% water change and just dump straight hot water into the tank to expedite increasing tank temperature. I should have done that earlier but people in the house still needed to take their baths. When the temperature was at the level I wanted and knew would be comfortable for the fish, I decided to make the call and put the fish into the tank. I let my younger brother who's not that young, net the fish out and put them into the tank as I knew he'd always wanted to see fish being netted into the tank, mind as well give him this chance to Christen the 75gallon with the fish.
Is there a kink in that tubing or is that the picture angle? If it's at an awkward angle, you may want to get a PVC or abs elbow to prevent kinking and subsequent flow stopping once the tubing gets too warm.
Gary you have eagle eyes

haha.
After I finished playing around with the tubing and wiggle some things behind the tank a bit; there was less of a kink, but at the time, I figured the kink will work itself away once the tube gets heated a bit. it was very stiff so I couldn't do much to it. It's so nice to see clear tubing and not brown tubing. It's like getting a new canister without having to buy one. I was planning to replace the gaskets this time around but figure I'll just replace them with the kit when the time comes.
Well here were some quick shots of the tanktaken last night/this morning - don't ask me what time...it was a long night

. The water is still a bit cloudy since I dosed a bunch of stuff in there and a lot of bubbles.
For the time being, I'm going to leave the rocks in there, but once I receive the sand from J&L's, I plan on rescaping towards a hardscape with minimal plants (I'll try my best) sticking with the South American theme. Since I plan on just a minimal layer of sand...probably less than 1", I will be growing the amazon sword in a basket fill with pebble rocks and my own DIY root fertilizer capsules. Btw, thanks to Mike at Fantasy for getting me a few plantlets of Amazon frogbit (the bigger variant that grows with attachments). Once I get a better ID on it, i'll get some pictures up with the name of it. Hopefully that'll help soak up any nitrates in the tank.
The LED lighting is columnized. It's more observable in pictures, but spreads out a bit more when looking at it normally. I'm going to play a bit with it and see what i can do, I took these pictures with the extensions out so it's laying flat on the glass canopy. This, however, does not provide the shimmering effect. I have since raised it back up and having it sit on the extension legs, looks much better.
Placed 4 big almond leaves and about 15 almond barks to add more tannins into the water.
So far, all fish looking happier with their bigger water volume.
