Well I finally decided to join you all instead of just using you for information. I have been surfing the web for months now to find the best way to construct a larger aquarium for my fish. I currently have a 150 gallon system, but my 6 main fish are outgrowing it. I am on a tight budget, but knew that a 500+ gallon system could be built for around $1,000 plus filtration and lighting. From my research it appears that Line X offers an aquarium safe coating called XS 350. I have never worked with fiberglass or epoxy before so I did not want to learn on my new DIY aquarium. Building the aquarium is no problem, but I am dreading the waterproofing step. The internet offers information about Line X coated koi ponds, but I am wanting to know if anyone has build and aquarium and then had it sealed with this product.

The following is just a bit of info on me, since this is my first post. I wanted you all to know a little about me. I have been a fish addict my entire life - 35yrs.. I have always done fresh water planted tanks, but switched to salt water about a year ago (My local government now adds chloromine to our drinking water. Very hard to remove and kills fish in hours). I live near the coast so I can get all of my water and fish food directly from the ocean. I have been doing this natural approach for a year now and have had no deaths in my tank, except for the fish small emough to be eaten in one gulp, so I am confident that the water quality I have access to is good. I was concerned about adding a large amount of wild caught feeders into my tank on a weekly basis, but no problems so far. This winter is especially cold so I had to do something a couple weeks ago that really worried me. The ocean near my home right now is so cold that all of the feeder fish and shrimp have gone into deeper water. I had to go to a local bait shop and buy about 5 dozen live shrimp. I cycled them through clean ocean water for several hours before introducing them into my tank in an effort to partially cleanse them. I hope none of my fish die. BTW the first 10 or so shrimp did not even make it to the sand befoe they were gulped down. Early Christmas lunch for my fish I guess. Anyway, that is my story so far.
 
"but I am dreading the waterproofing step."

Do a test model first, a potential sump maybe.

All coatings have different characteristics...drying times, 2nd application times, recommended coating thickness, durability, flexibility and such.

Good luck and enjoy.
 
chlorimine isnt hard to get out of water. Prime or a chlorimie filter gets rid if it.

i used sweet water epoxy. it went on like paint. when you do the correct thickness it dried in a few hours. i kept it in the pot for 48 hours with out hardening. because i kept i cold and air tight.
 
Burko,
I am plannign a test run for the waterproofing aspect, but I was wanting some reassurance on the marine safe aspect of line x. Also, the one coat then ready to fill aspect is appealing.

You'll end up spending more on fish and food in the long run so take your time and give them a nice home that you won't have to worry about.

Tests are good.

Patience is good.

Flooded house bad.
 
nes999,
I learned the hard way that not all chloramine removers remove enough to make them fish friendly. I was using a chloramine remover when I did a water changes in my goldfish tank. Within 6 hours all fish were dead. Shame since one was a fist sized chocolate oranda that I had for years. I thought it may be something else in the water, but tested it and saw no other impurities. When the county I lived in used chlorine in drinking water all was good, but I have been unable as of yet to find an EFFECTIVE chloramine remover.
 
So why exactly have you chosen Line X? I looked at the site and read their brief description of XS-350 and Ive never heard the term "moisture insensitive" when describing a product that was to hold water or "low permeability rate" which is also used to describe the product. To me Low permeability rate and moisture insensitive means that it does not waterproof more than it means it will shed water and resist short term submersion and is not meant for constant submersion and it will let water through eventually. Did you speak with a Line X rep? I would also do more research on polyurea since that's what the product is made of. What is the cost of the XS-350? I used Sweetwater epoxy and I've had no problems at all for 2 years its $73 a gallon but as nes99 said it goes on very easy, has a long work time and if you seal what you haven't gotten to and keep it cold it will keep for a while and definitely long enough for the next coat.
 
The other concern with linex type products to me would be surface adhesion. At least in a truck if the surface isn't "perfect" the linex can peel... I don't know if it applies to this product though.
 
Muni,
I agree full heartedly with testing and having patience. I plan on researching for many more months before building my tank. I can not afford to spend more money then I need to and a leak would have me sleeping on the couch for an indefinite amount of time. My plans are to make a tank 10 x 3 x 4 with the stand being selaed as the sump. The stand/sump will be 14 ft long allowing for a 2 ft hang over on either side for mechanical filtration. I currently have large amounts of live rock in my 150gal setup and will use that and bioballs for biological filtration. All my fish and fish food are taken directly from the ocean near my home, so There is no cost there for me. I also get all my water from the ocean. So the only 2 real costs for me are tank and stand contsruction and the minimal cost of changing out mechanical filter media.

Since the tank will be setup and run for hopefully decades I am wanting the longest lasting seal I can get. That is what interested me in Line x. Also I have lots of crabs that may pick at the sealant so it needs to be very durable. From experience with line x spray in liners I know ther products hold up.
