View Full Version : Prop tank project hits a snag...

So, it's ironic. I just had taken photos of my recently completed prop tank setup to share with my friends here at Talkingreef. It's really wonderful. Well, it WAS wonderful. Two 29 gallon tanks, one for soft corals / lps corals (lower light), one for sps corals (higher light) and a large 55 gallon sump/refugium.

The only thing that was not finished was the addition of a calcium reactor, and a phosban reactor - just trying to get my finances together, couldn’t quite afford it yet. Otherwise, this bad beeeyach was up and running, corals were happy and growing, and everything was perfect!

Like I said... I just took photos. I was JUST getting ready to post them here and show off all my hard work. Then about 2 weeks ago I walk downstairs to find at least 25 gallons of water on the floor, and my new prized sump leaking like a sieve from the skimmer compartment.

I nearly cried. What a stroke of bad luck! Although we can’t be sure why, the problem was that the tank split a seam. There were two things going on here, first, my bubble trap box (aquarium is glass, all the inserts are acrylic) was just a noodge too wide, and instead of taking it out and re-building it, i tapped it into place. What a stupid move.

Secondly, I use large, industrial wire rack shelving for this project. The 55 gallon tank takes up (width-wise) about a shelf and a half, so it crosses the center. The problem that I had not considered previously is that these racks, at the end, are not flush. They rise up just a tad all the way around. So, even though both shelves were level, the tank was setting on a high spot. Either one of these, or a combination of the two are what did me in.

And if I had been using my BRAIN... I could have dome something to stop it.

Of course, I got the 55 gallon used for a great deal, so there is a chance I got a bum tank, but I think its more likely that my error caused the failure.

Anyhow, my buddy Ian who drove over and helped me get a temporary 29 gallon sump in place. He also took my refugium inhabitants and gave them a temporary home in his tank.

From there I had to make a decision...

(1) acquire a new 55 gallon tank by whatever means I can (note again that my budget is shot), learn from my mistakes, and craft a new sump, even better than the last one.

(2) take everything I put into the existing tank (baffles, etc.) out, and attempt to re-silicone everything. Then put everything back in. Of course, this would have been excessively time consuming, and might not have ultimately worked.

I decided to buy a new tank, so I had to sell some of my corals to finance it.

So as of last night, the new sump is in, the plumbing is done, and everything seems to be working. I built the bubble trap box VERY differently this time, so potentially stressed/bowed glass will never be an issue again, and I put a 3/4 sheet of exterior grade plywood with a 1” sheet of industrial foam on top of that.

I’m hesitant to take/post photos... I am totally paranoid... but I probably will within the week.

Thanks for sharing that horrific story. I think something like that is just about everyone's nightmare.

But it's good to know about the stress you put the tank under when you squeezed in the baffle. Easily sounds like something I might have done! At least we all can learn something from this.

Yeah baffles should NOT have tight fit. there should be about 1/8 to 1/16 gap on either side. If you have to squeeze it in, you may have problems. The sump on my first prop tank cracked, fixed it with some silicone and a piece of acrylic. Not pretty but worked... probably the same issue. Funny how you read all about stuff like this AFTER you do it and not before.

hehehe normally I would say "happy to help" or "no problem" but instead I will just say "you're welcome" if you know what I mean. ;)

Jeff -

That stinks! You know what they say about the best laid plans ...

Sounds like you made the right decision, IMO. Now get those photos taken and posted!

Jeff, I am so sorry you have had this happen. I think that you made the right decision. Thanks for sharing this disaster so we all can learn.

oh nooo, what a bummer dude, its the season for bust outs im afraid, seems to be following a trend in batches between all us, but then again, statisticly, thats alot of people.:no:

ouch-- the baffles are acrlyic, a simple cut would have solved your problem, gaps are not just for flex, it allows for bonding of the sheet to the wall from both sides, however i didn't think silconing acrylic & glass together worked too well to begin with>>??

Now that you know what not to do, im tipping the experience will produce some wicked future results bud.

veriann, I have actually been building sumps using glass aquariums for a bit now. I guess I am too chickenshit to build the actual box. :) I think it works well and the aquarium silicone is surprisingly strong. Of course, now that I am actually gapping on either side of the piece we shall see if I still feel that way in a while, as some of my strength was coming from wedging it in between the glass.

As for a simple cut... not so much. I actually build the bubble trap as a box, so I would have has to waste over a half sheet of acrylic. Still not a good decision, but I don't want to make myself out to be any lazier than I actually am.

nothing wrong with being lazy, i try to do it often!:tongue2:

yeah i must have missed that point about making the bubble channels within box form. quite smart actually. considering your using an existing structure & placing it in, well on the next one anyways.. :D

Plus considering how little space is between them, and since they need to be glued on two sides for structural integrity, I would have to have the hands of a five year old girl to get the job done. The box is really the only way I could figure out how to do it.

Well if nothing else... I really wasn't a big fan of the plumbing the way I had it. Of course, I'm not certain my "improvements" are much better hehe
