Too much for a 75 gallon tank?
So I've got my new 75 gallon heavily planted, CO2 fertilized tank set up and cycled finally. Lighting of two Kessil A360X with spectral controller X, API Filstar XL Large, Eheim 350 surface skimmer, heater set to 78.8 F (roughly 26 C), Twinstar Yotta + electrolysis sterilizer, and on hand Marineland Magnum internal diatom filter, and an Aquatop 9V internal UV sterilizer/ filter (both of which I only utilize when absolutely needed because I hate to have those bulky contraptions as a permanent eyesore in the tank).
My stocking list including inhabitants of the previous 29 gallon tank is: 1 Bristlenosed pleco, 5 Clown plecos, 7 Otocinclus, 4 Bolivian Rams, 30 Cardinal Tetras. Would I upset the balance too much by adding 15 - 20 Rumynosed Tetras? I had originally planned to add 10 Blue Velvet Shrimp but a friend convinced me that neither the temp, nor the Cardinals, or Rams were optimal for shrimp even though there are plenty of hiding places with all the driftwood and plants.
What is your take on this?
Forgot to mention that half an hour before the lights go off the CO2 shuts off and a Tetra Whisper 100 air pump comes on which in turn shuts off half an hour before the lights come on at the same time as the CO2 comes back on, to avoid any night time oxygen shortages.
