I just thought I would ask to see if anyone had a 30" light they wanted to get rid of.
Im looking for a 130 watt minumim.
I think that is enough for a 20 long to grow sps. If you dont think thats enough let me know so i dont get the wrong thing.
For most sps corals no, that won't be near enough PAR to satisfy their needs. However if you keep up on water quality montiporas would do ok and most lps and soft corals would do fine with that light. If your looking for a cheap MH fixture check out hellolights.com or if your any good at DIY you could try this
