Fishkeepa Posted July 24, 2006 Report Share Posted July 24, 2006 I recently brought a 100L tank that needs a reseal in some areas. So im wondering - And this question has probably been asked many times before what can i use to seal it and whether i can put the new silicone over the old scraggy bits of silicone. Is there anything that would readily available from hardware stores to do this? Thanks eveyone Quote Link to comment Share on other sites More sharing options...
suphew Posted July 24, 2006 Report Share Posted July 24, 2006 Best if you can remove as much of the old silicn as you can, but leave the silicon in between the glass joins. if the silicon in there has come loose you are best to remove the whole piece of glass and reglue it all. You can get away with not doing this but it is the best option. You need to get the right type of silicon, there are two, acidic cure is the one you are looking for, often they have 'for aquarium use' written on them. Also make sure you get one that doesn't have mold inhibiter in it. The correct silicon has a very strong smell, and must be used in a well ventlated area.

TM Posted July 24, 2006 Report Share Posted July 24, 2006 best glue is one done by fosroc glass and ceramic Quote Link to comment Share on other sites More sharing options...
Alan Posted July 24, 2006 Report Share Posted July 24, 2006 If it needs resealing in several places as you say, strip it all down and rebuild the whole unit. If the glue has gone in some areas, then the rest is not too far behind. Use acetic cure silicon for any repairs or the rebuild.

Fishkeepa Posted July 24, 2006 Author Report Share Posted July 24, 2006 Any particular brands that i should look for that i can use Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted July 24, 2006 Report Share Posted July 24, 2006 I use Sellys because it has " suitable for aquaria" on the label and it is the cheapest. So long as you use one suitable for aquaria the only real difference is price and consistency. The latter is a matter of personal preference and is only relevent if you are going to make lots of tanks. I would agree with the previous advice about a rebuild. Clean off all the RTV you can and clean with meths. If the inside fillet is in a bad way the rest probably is as well. Quote Link to comment Share on other sites More sharing options...
Fishkeepa Posted July 25, 2006 Author Report Share Posted July 25, 2006 Most of it looks in good condition but along the vertical joins there are big chunks missing but I might try the total rebuild Quote Link to comment Share on other sites More sharing options...
quack Posted August 2, 2006 Report Share Posted August 2, 2006 im about to make my new tank in the next few days and want to make sure that i get the right silcone. in tanks that i have made in the past i have used a natural cure. but from what people are saying on here it sounds like i should be using acidic cure. i thought that the acidic cure would leech out contaminates into the tank water. am i rong?

quack Posted August 2, 2006 Report Share Posted August 2, 2006 yes i have read the label on that one but that is also a acidic cure. im sure itll be fine just wanted to be sure Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted August 2, 2006 Report Share Posted August 2, 2006 The smell of the acid cure is acetic acid (vineger) and I have made hundreds of tanks and licked my fingers when smoothing out. I would think that if it is not toxic to me it is not toxic to fish. I also eat pickles. If it says suitable for aquaria on the label it probably is.
