We noticed today out 3ft tank is leaking,From what we can tell on the right hand side on the corner we THINK about halfway up there must be a crack.you can feel its damp from there downwards and inside the cupboard on the stand inside is all wet with a puddle in

So what on earth are we going to do?

We have the 300 litre but this is currently undergoing a fishless cycle ready for the cichlids and we do have an empty 65 litre tank but thats no ideal due to it being smaller and the fish we have in it theese are:

5 guppy's
4 mollies
2 dwarf gourami

and inside this we have a breeding net holding 7 fry which are 2 weeks old and 4 other fry which were born just lastnight.Should I syphon the 3ft tank into the 65 litre moving filter inside too and transfer the fish??

And is there a way we can fix this leak? Its not water splashes its def a leak so obviously I need to empty this tank asap just in case the leak gets worse.

drain the tank to below the leak pint and get a tempory tank you can put them in whilst you fix the leak then leave 72 hours before filling back up

I would transfer to the 65 wholesale.


Then you need to completely dry the leaking tank. There should be tell-tale bubbling in the silicone seal where it has broken down.

However, remove the surface seal from the whole run (top to bottom). You can do this by slicing with a Stanley Knife blade flat against the glass from either side.

Use a solvent cleaner to remove any silicone residue. Allow 24 hours for any solvent to evaporate.

You will probably notice under close inspection, a tear or pin-prick hole in the structural silicone. Don't try gouging this out. Just neaten this area up.

Apply a bead of silicone along the length into the joint. A bead about 8mm wide is plenty. Smooth this out with your finger (suitably dampened in a bowl of water - don't try and smooth silicone in with dry fingers!) If you need to run your finger along the joint more than once, make sure you wet it each time - this prevents the silicone sticking to your finger and pulling out of the joint.

Leave for another 24 hours.

Check that the silicone has adhered to the glass by lightly rubbing the edges. If any silicone peels off, the glass was not dry to begin with.

If the above check is OK, apply a wider bead of silicone (about 10-12mm wide to match the other joints), smoothing this in as you did before.


Leave the tank for 48 hours in a warm dry place for the silicone to cure.


Next you need to water test. Do this in a shed or garage in case it leaks again.

Fill the tank and mark the fill level on the glass with a marker pen or chinagraph pencil. Put the hood on and leave for 48-72 hours.

If the level has remained the same, give or take a couple of mm for evaporation, then it will be fine to reinstate as a main tank

am I checking for the bubbling while the water is still in to see where the leak in and then syphon it into the 65 litre?

I have transferred the fish and some water into the 65 litre.with the water inside halfway up the tank there is no visible leak???

I swear it is leaking but now looks like i might just have to scrape all the silicon off on that side and re do it and see if that works? would that be the best option?
