Re: Just started my 20 gal reef lol i have no experence with a DIY light for my tank but if you look online like at shops such as marine depot in there lighting section you will see something called retrofit kits those are like DIY lights its like a packaget hat comes with the parts so its cheaper so shop around for those but i think those DIY light are only if you have a hood ontop of your tank so if thats the case i think a clip on or pendent light fixture would be your best bet it would cost around 300$ |
