35ppt Posted October 1, 2015 Report Share Posted October 1, 2015 My sponge filters have gone 6 hours without air.6-8 gallon tank @ 77FHas a tiny HOB that has been running nonstop, so there has been filtration.The one sponge is normal size for the tank, and the 2nd sponge is about 5" (at least twice as big as the other one).These are RCS, hard to count because of the plants. Probably 30-50 of them.People always caution about mini cycles after such events, but now that I've had one, I realize I'm not sure what to do now.Like, when should I start testing params?I was actually about to do a water change anyway, would that actually interfere with re-establishing the cycle?

chibikaie Posted October 2, 2015 Report Share Posted October 2, 2015 Check now. That will let you know if you need to deal with an ammonia spike. Frankly, I would be surprised if you had a mini cycle from the situation you described. Quote Link to comment Share on other sites More sharing options...

DETAquarium Posted October 2, 2015 Report Share Posted October 2, 2015 I wouldn't worry so much! You won't have any mini cycles because of the power outage. Quote Link to comment Share on other sites More sharing options...
35ppt Posted October 3, 2015 Author Report Share Posted October 3, 2015 Figured I'd better be safe than sorry, right? I wonder how long, without any filtration, would be an issue? Anyway, checked my params, and then again later, and everything looks good. I even managed the vacuum (airline, lol) without getting any little ones sucked up.

DETAquarium Posted October 5, 2015 Report Share Posted October 5, 2015 I went through this very same thought process for a number of days about 6 months ago. I decided that the investment I had in my shrimp was not worth the loss, so I purchased an APC UPS 1500 system for all of my canister filters. It would keep all of my filters on for an additional 2 hours at the very least. Quote Link to comment Share on other sites More sharing options...
