Leaking tank - HELP!
I've just carefully refilled my Juwel Rio 125 tank after having to move it - it has no fish but now has plenty of Florapol fertilizer underneath the gravel, etc.
Except 2 days later it became apparent that there's a leak. Only a few mls a day, but still.
Is this fixable? What sealant might work? I assume I'd have to take all the water out again...
Or do I need a new tank? :(
