Someone loves their 250 gallon tank - but has a problem on this forum. It has a crack at the bottom - what to do - They are using a rubber bladder currently

here are 2 Ideas that may bring enjoyment back to your tank without the plastic bladder ruining the view. The second method is way less complicated and would probably resolve your crack problem.

One method: Take a piece of black plastic - larger than the bottom of the tank - and place it underneath - drill a hole thru the plastic and the wood base. Seal the plastic between the exposed area of the plastic hole and the wood base by taking regular aquarium sealant and placing some around the hole under the plastic. The hole can be a quarter to a half inch - enough size to over-ride water tension yet allowing a cork stopper to fit the underside of the hole in the wood. Allow the sealant to dry.

Next - there are two ways to do this - you can cut a piece of clear plastic longer than the size of the crack and slightly wider - 2 pieces. take regular aquarium sealant and place on each piece on one side - sandwiching the glass in between - let it dry for at least 48 hours as water is over 7.5 lbs per gallon.

Place the tank back on top of the plastic. with the aquarium sealant lift the tank edge and cover the entire edge all the way around the tank and allow it to seat on the plastic - smooth the excess sealant out. Fill your tank with water. The tank should not leak at all. In fact I know people who cut sheet window plastic - place the sealant on one side of the sheet - and place it in the inside bottom of the tank pressing the plastic down to allow the plastic sheet to seal - allow tyhis 3-4 days drying time. Thius way you can disguard the plastic bottom idea and so -on.

The plug in the hole lets you monitor the bottom of your tank to see if there is ever any future cracking (if you do not put in the plastic sheet there may be more stress cracks on the way. As well if another crack occurs - the sealed edges of the plastic and the cork stops the future outflow into the room.

Second temp method : DRSFOSTERSMITH.com has an aquarium sealant that does not affect the fish but dries under water - . take a piece of window plastic cut to cover the plastic - on one side place the sealant and place on the inside bottom of the tank - overtop of the crack. it will dry underwater, will stop tyhe leak, and will not harm the fish - you can remove the bladder.

All people with glass bottom tanks should seal the edge of their tank bottom with aquarium sealant - to whatever solid top you have it sitting on - You do not have to lift the tank - just seal around the edge like you would do with glass to glass. this could sabve the life of your fish and give you time to remedy a bottom crack.
