have your tried Orphek Atlantik lights and used their app for light control ? i gave mine up after a year because it was so buggy and PITA to adjust just one, let along i had two of V4 Gen2 lights.
i'd say at this point don't add anything, and let your tank cycle for good 1-2 months. wait it out. dont buy any fish/corals. just sit on your hands wait it out.
next time if you want buy plumbing under budget, get pvc from HDX and just buy one expensive gate valve. you could save half the cost. ( that's if you dont care about the looks... some people hates white PVC )
and stop people advertising our club's DBTC as a FREE coral perks after you join. this bug the hell out of me when i over heard this from other new upcoming reefers.
ok they just sent out the 2nd unit back to me. let see if they truly fixed the unit without any errors.
@Chromis have you got any of your units back or paid yet ?
