Knew this would happen

[BC Mosaic]

I have a ZeoVit system/reactor in my sump. Twice a day you're supposed churn the Zeo rocks by using the top handle and pumping up and down. That's 1 1/2 litres of rock and water moving up and down and that takes effort and force.This twice daily "maintenace" has caused me some concern; I wondered if the bottom glass would crack eventually. The sump is a 33g glass tank with baffles and now it has started to leak in the area where the ZeoVit reactor sits. My sump is a typical sump - crowded. There's a bucket underneath the sump catching the drips and of course the ATO is fuctioning perfectly but with the slow drip loss of salt water and the ATO doing it's job the salinity is dropping. Tomorrow during daylight I'll have to try and blindly silicone the inside of the sump tank and hope it works. If the reef tank suffers because of the silicone (yes, I'll use aquarium friendly silicone) then I just know that I'll just chuck the whole dam hobby into the dumpster. This design is asinine. So for those of you that have this same set up, I suggest that you lift the thick rubber top off and just swirl the stupid stuff with the handle instead of trying to churn it.
Sorry for the rant, but I'm really frustrated by this hobby now and that was not the point of getting into it.

I think that maybe I'll just stick to my fly fishing instead.
Tight lines.

that sucks to hear
but you can get aquarium safe silicone at rona the rona brand it says right on it aquarium safe i used it in my sump and my buddy used it in his and his 15 discus have been good for over a year and its 5 bux a tube vs 20 at the lfs

If you put wet silicone, or silicone that has not cured for at least 24 hours in your tank, I can promise you some nasty results. I can tell you first hand that silicone that doesn't properly or fully cure kills, and quickly.

I've never really had a concern with pumping my reactor. I use my one hand to hold/support the reactor and then pump with the other so it does not move around much.

Have you posted this on the zeo forums to see if this has happened to anyone else? Just seems like a freak thing to me.

Hello Greg,
I use two hands as well; couldn't do it any other way.
I started using Zeovit about 1 1/2 months ago and I guess the twice daily churning has created fatigue along the silicone somewhere. I should have listened to my inner voice. It's only logical that if pressure is exerted on glass it'll eventually give. I will not "pump" the reactor ever again but twirl/spin the rocks.

michika,
I've got no choice.

Thanks e46er

Hmm it just seems like there might have been a pre existing flaw in the sump tank itself, I've been pumping zeo for a year and have not had any problems.

If you are looking to change reactors there is that one available that has a screw type device and you turn the handle to agitate the zeolites as opposed to pumping.

Sorry to hear about sump BC Mosaic
I've been worried about the same thing happening, or a pebble (zeolites) getting sucked into the main pump. My reactor has a crack on the top of it. I've lined the bottom of my sump with a piece of acrylic to protect it

I've been using Zeo for almost 3 years now and the thought never dawned on me. Mind you I think a 90 Sump may be more forgiving.

Sorry to hear of your leak

You may want to support the glass with a sheet of foam insulation. At the same thickness as the distance between the floor and the glass

Thanks guys.
The sump used to be one of my FW tanks. The glass is 1/4" thick so a thicker glassed tank like a 90g (?) will have more surface area contact with the silicone. I am completely convinced that using this reactor exacerbated a problem although if left alone (no reactor pumping) it would have not materialized to become a problem. Regardless. I had a chance to vent and had my suspicion confirmed and a happening that could occur to any other glass sump with a Zeo reactor or any other pumping required reactor. Something to be aware of or else just get the "screw type" reactor.
I'll be taking the lid off my reactor permanently and just spin the handle and if really need be I'll use a plastic rod to stir it up.

Drain your sump, or find another way. I am very serious when I tell you that wet silicone in your tank will destroy your system. I had to start over from SCRATCH, everything, rocks included.
