MaiDong Posted June 1, 2013 Share Posted June 1, 2013 My wife recently came home with some plants for inside our house, the type of plant that sits in water, the only problem with that is the water then becomes a breeding ground for mosquitos, so we were going to put little fish in them to eat the larvae, which we have done before, with varying degrees of success(plants dying, fish dying etc), she also came home with some red clay pots which would hold water, according to the shop... The pots began leaking, unsurprisingly, so my wife went back to the shop and bought some more, this time of the cement type, when she told me about these pots I thought they would be the polished cement type but they weren't, she returned from the shop and they were the rough-finish type, which the shop said again would hold water, but as soon as I filled them up to test them they started leaking, through the entire surface, like sponges. We asked a few people how we could seal them, my neighbour suggested silicone, the type which seals the glass panes together in a traditional fish tank, using silicone 'guns', but I can imagine that taking a long time to do and would also work out expensive, she also suggested a type of cement, to line the inside of the pots, which wouldn't kill the fish(apparently the cement they were made from WOULD have killed the fish! Has anybody got any ideas? Link to comment Share on other sites More sharing options...
krisb Posted June 1, 2013 Share Posted June 1, 2013 Cool pots! How about go to a hardware store and buy the waterproof/rubbery type paint tilers use for waterproofing bathrooms before they tile. Its designed to be wet and not peel away and would be long lasting. All I can think of. Link to comment Share on other sites More sharing options...

GottaGo Posted June 1, 2013 Share Posted June 1, 2013 There are plenty of paint/sealants but you'd have to find one that wasn't toxic to your plants and fish. Bathtub repair paint? as in for human baths, but since most here are fiberglass now. . . Probably better to just buy proper pots with a fired surface finish, maybe even test them out before paying for them (fool me once. . .). 1 Link to comment Share on other sites More sharing options...

shaggy1969 Posted June 1, 2013 Share Posted June 1, 2013 Have a look at this topic Maidong. I remember the poster wanting to seal his concrete Koi carp pond and Flintkote #3 was recommended.

Chokdee Shaggy Thanks for the link Shaggy, seems ok doesn't it, shame it's dark though, we're only going to have those small black fish with metallic green tails(guppies?) and some of the pale orange similar-sized fish but at least the paint will be doing its job, and the fish doing their job too! I wonder how the stickiness went down with the fish brushing onto the sides though, and also if moss started to grow as that's mostly what our little fish eat anyway...

canopy Posted June 2, 2013 Share Posted June 2, 2013 I used the Lanko mentioned to seal a concrete ring pond that leaked. I just troweled a light coat everywhere inside. Very satisfied with the results and I believe it is even approved for water potable applications. Highly recommend. Link to comment Share on other sites More sharing options...
NanLaew Posted June 2, 2013 Share Posted June 2, 2013 Jake's rather simple solution was discounted as 'stylish' by the OP. But you can but loads of white or clear bin liners at Makro (for example) and if the algae build up is beyond the little fishes eating capacity and the pot turns green inside, just replace the bin liner. You can get a whole lotta bin liners for 250 baht as well. PS. Has the OP asked the little fish if they like light or dark coloured walls in their prison? 1 Link to comment Share on other sites More sharing options...
xylophone Posted June 2, 2013 Share Posted June 2, 2013 What about painting the inside of the pots with good old fashioned varnish? A couple of coats should seal them ok. Link to comment Share on other sites More sharing options...
canopy Posted June 2, 2013 Share Posted June 2, 2013 It's hard to understand why disadvantageous suggestions are being offered after cheap, easy, and readily available solutions are already recommended. you can but loads of white or clear bin liners at Makro (for example) and if the algae build up is beyond the little fishes eating capacity and the pot turns green inside, just replace the bin liner. Can't see the logic in this. Such plastic deteriorates quickly by sun alone and will leak. It is also a waste of plastic and requires routine maintenance that should be totally unnecessary. A balanced pond never gets too much algae growth and judging by the many container ponds I have seen in Thailand as well as my own it is really easy to let nature handle this job. What about painting the inside of the pots with good old fashioned varnish? Sounds detrimental to pond life, even if it stops leaks which it may fail to do anyway.

I must have lived too long in (cold) countries with very few swimming pools because I've never swam in a pool that isn't entirely lined with tiles... But back to my main concern however, the fish.

Sounds detrimental to pond life, even if it stops leaks which it may fail to do anyway. Exactly, as soon as I get some time, hopefully early this week, I'll get some Lanko, knock it up, slap it on, and hopefully it'll be the kind of finish we were originally after. I quite liked the sound of Flintkote but it would possibly change the finished look from cement to a more clinical look, which my little prisoners may not appreciate, eh NanLaew Link to comment Share on other sites More sharing options...

From the pdf file (translated by Google): Tar sand for mortar to prevent leakage. Kind of flexibility. Special features. - Flexibility, resistance to cracking as well. - Both internal and external. - Non-toxic. - There are two colors: gray and white.
