I am selling a 40 gallon breeder for $50. It is in great condition. I had intended to build a frag tank, but we got pregnant and everything else got in the way. I just don't think that I will get around to using it and hate seeing it sit empty. Let me know if interested, I will definitely...
I wouldn't overflow into the tank below. Have both of them overflow into the sump. And the middle tank needs to have a valve on the supply side to restrict flow. A valve is not needed for the top tank, unless you want it as an isolation valve.
I'm going to start in a few days. If you read SunnyX's tank post in the SPS keepers section, it's an amazing resource for vodka dosing. He recommends using Brightwell Aquatics' MB7 a few days prior to dosing vodka. That's what I'm planning at least! Hope this helps!
Right now it's on crest mode probably at 30%. I can't hear the motor over anything else in the room. But I haven't had a chance to really mess with the settings yet. Hopefully I'll have time to tonight.
I have an MP10. I put in on a 20L last night and didn't think it was very loud at all....And it's supposed to get quieter in time...I'm ultimately putting it on my 40B, but I haven't gotten that up and running yet...
I would be worried about the large temperature swings though. 74.7 to 77.8 fluctuation is quite a bit. I think that the heater (as long as it is watched, to make sure it doesn't malfunction and overheat) is a good idea.
My heater was malfunctioning this summer and the tank was consistently running 85 degrees during the day. I lost several SPS, but my fish had no problems.
Just wondering, if the fish did happen to have a parasite, wouldn't the higher temperatures help it complete its life cycle faster?
Absolutely! Although, I wouldn't pay the premium for the "live sand." The tank will make it live pretty quickly.
I would just put a powerhead in the bucket to keep it oxygenated.
