Hello, in my 5 gallon tank my drainage layer has flooded.Now before anyone thinks im keeping frogs in. 5 gal im not its a temporary tank for my 3 green tree frogs while their 20 vert is being constructed.anyways...my tanks drainage layer is flooded with water and it is slowly spilling out of the tankIm using gravel as a drainage layer and i was wondering for future builds does it matter if i use gravel or hydrotone?Will the water in the drainage layer evaporate?To avoid this problem for my 20 high i just siliconed the whole inside edges of the tank.thanks
