Aquarium Advice Addict
Hi everyone! I am very excited to have upgraded my lights on my 50gal (well, technically its 55 but the interior measurements filled with water & substrate hold 50g). It came with (3) 12k bulbs & actinic stock but i also ordered (4) 65k bulbs as well. For now, i replaced two of the 12k bulbs with 65k bulbs to see how this combo looks. So, my question is this- do the 12k & actinic bulb serve any purpose beyond just asethics? Are two 65k bulbs enough for low to medium light plants or should i replace the remaining 12k as well (esp if i want to try some more difficult plants)? Will the 12k bulb grow anything? I do not have a co2 system & will not be using one (my fish come first) but i dose flourish & excel with water changes (which are frequent). Should i just give the bulb combo i have in now a try & see what happens? Any advice is appreciated!!! Thanks!
