Okotoks Posted April 15, 2011 Report Share Posted April 15, 2011 I have a 20 gallon tank I want to start an Iwagumi style in. It has a single 18" light in the hood. I will be using a Fluval 204 canister filter. I am planning to use Glosso primarily as the carpet with some java moss and maybe a small sword or Ludwigia in the background. Will this 18" light be sufficient? What substrates would be best? Quote Link to comment Share on other sites More sharing options...
jvision Posted April 15, 2011 Report Share Posted April 15, 2011 The light can work, but it will take a LOOOONG time to get your Glosso carpet, and it might start growing up instead of carpeting. If you can upgrade to a couple 24" bulbs - T5HO would be best, IMO. Glosso does best with a good carbon source - Excel will suffice if you don't have a CO2 system.
