Brand new here and soliciting advice for a future 75g build

[rawalstrom]

i'm planning a modified Orinoco biotope for the future and am interested in comments/suggestions/critiques/and helpful hints.
The tank list consists of:

75 gallon tank

water ph ~ 5.5 - 6.5
water temp ~ 82 F

eheim 2126 pro II thermofilter w/spray bar
hydor circulation pump(s?)

dark sand
driftwood
pink granite

moonlight - in tank mount and waterproof
t5 48x2 - 2 (6500k x 2 and 6500k + colormax)

water lettuce - pistia stratiotes
red amazon swords - echinodorus sp. 'red special'
tiger temple plant - hygrophila sp. 'tiger'
brazilian pennywort - hydrocotyle leucocephala

green laser cory - 4 - corydoras aneaus sp. 'green laser'
orange laser cory - 4 - corydoras aneaus sp. 'orange laser'
huarani oto - 10 - otocinclus huaorani
electric blue ram - 4 (2 pair) - mikrogeophagus ramirezi sp. 'electric blue'
cardinal tetra - 20 - paracheirodon axelrodi
purple tetra - 20 - hyphessobrycon metae
marbled hatchetfish - 10 - carnegiella strigata

*maybe*
L-129 orinoco zebra pleco - 1 - hypancistrus debilittera


*back-ups*
rummy nose tetra - hemigrammus rhodostomus
green neon tetra - paracheirodon simulans


I want to do a low-tech/lower light set up so I went with plants requiring lower doses of co2 and light. I will probably be dosing my tank with Seachem Flourish and Flourish Excel to help boost the plant life. The modified component comes in when I introduce the hybrid plants and the color variations of the corys and rams.
Is there any concern that I would be over-stocked?
Is my filtration adequate?
Anything else I should be worried about?

Your plan seems well thought out, and should prove to be quite acceptable, including your projected bio-load, although some might say it could be a touch on the heavy side.

And with that lighting, set-up, size of tank, and stocking, etc., I believe your biotope will be quite attractive. Small point, but do go with the Hydor pump, you won't regret it.
Looking forward to some pics when you get it done.

P.S. - Orinoco - with pH of 5.5 to 6.5 - and 82 F temp........ What, no discus ?
I'm disappointed (tongue-in-cheek) - perfect for discus ! (Chuck the hatchetfish and otos - perhaps some of the purple tetras, and get 6 discus - LOL )
Just kidding, do what turns you on.

I've been dreaming about a discus tank for a couple of years now and I believe I'll 'graduate' to them when we move into a house. Our 65g community tank will probably end up being a discus tank.
