3 day blackout leave fuge light running?

[e46er]

so my fish are all in a hospital tank and my DT tank has crazy algae so im looking at this as a perfect time to do a 72 hr blackout and a massive WC after day 3 but i am thinking i should leave my fuge light on to continue to uptake nutrients and so the chaeto algae doesnt die.............. good idea or a brain fart?

Yup, Ive done that. Left Sump on the normal light cycle, whereas tank was Lights out. I do it every few months, with fish in the tank. Just remember to light acclimate after. Even corals will be shocked if just resume full light schedual

new tank just snails and a 2 brittle stars still need to light acculamate??

thanks for reply

New tank, How new??? If its fairly new it may just be the normal cycle and taking fish out/doing lights out may screw with the cycle.

But No, Snails and stars shouldnt need any light acclimation

well finished cycling back in first week of december i just meant no corals or anything yet added the live rock in mid october i guess

Ya, a lights out would be fine. I started doing mine about then. What I'm thinking though is thats still part of the cycle. Mines been about a year now since I added LR. Most algae is gone, but still have occasional cyano problem.

Think I need new lamps now though is my problem
