I have an RODI system for trade. Main 3 membranes in good condition. Only need to clean top 2 chambers. I'm looking for a new skimmer for my 75g or maybe a reefkeeper lite or even Chinese LEDs. Let me know what you got and I would be happy to throw cash on my end as needed. Also have a t5 I could throw in to sweeten the pot. Thanks. Text 9492434337 for fastest response. Located in 92675 but can meet as far as irvine or Oceanside to the south.
