Upgrading my 75 gallon tank (need help with lighting)
I currently have a 75 gallon planted tank with 6 clip on lamp lights equipped with 6500K and 1600 lumens per bulbs (total of 9,600 lumens which is kind of low for a 75g). I do excel flourish dosing everyday with CaribSea Eco Complete. But I am planning to rescape my tank next week and get more susbstrate and possible add fert tabs (its 3 inch deep atm).
As for the setup that I have atm, I am getting 37 PAR. But after a couple of failures to grow some plants, I decided to upgrade my lights and possibly add a CO2 system (any suggestion would help!).
My budget is around $200 to $500 (leaning towards $400) and has thought of getting two sets of either (48 inches)
Odyssea T5 Quad Timer Aquarium Light Marine FOWLR Cichlid or FLUVAL 3.0 PLANT SPECTRUM or BeamsWork DA FSPEC LED or Finnex Planted+ 24/7
I also have some old lights lying around( Current USA Satellite Freshwater LED 38inch and $100 marsaqua ebay lights) but I am not sure if they are strong enough.
I am planning to have had a carpet plant, Alternanthera Reineckii, Ludwigia, and some other plants (heavy planted tank).
Any thoughts on the lightings that I have listed?
Thanks in advance!
