timmyg Posted June 14, 2017 Report Share Posted June 14, 2017 90 Gallon Fresh Water Planted Tank. 2-3" of rock substrate. Have owned the tank since new. Has been set up for 10 years. Has calcification along the front half bottom edge where glass meets the angle tank base (black part) . No other calcification on tank anywhere. No way water is getting to this spot except through the bottom of the tank. Anyone else know if this is an early sign of the tank loosing its seal? thanks Tim Quote Link to comment Share on other sites More sharing options...
jvision Posted June 14, 2017 Report Share Posted June 14, 2017 I've seen water whick through the top black brace/trim and drip, causing what you're describing Quote Link to comment Share on other sites More sharing options...
ckmullin Posted June 15, 2017 Report Share Posted June 15, 2017 Have an old tank that if I fill too much as jvision states it wicks UP, between the glass top and plastic trim. If you think it's this...tape a little strip of tissue along the glass just below the trim above the area you have concern. You don't have to see it happen but once the tissue gets wet it will change the way it looks and that can easily be seen. Fill the tank to the top as well to at least rule this out.
