Robbo2232 Posted August 16, 2009 Share Posted August 16, 2009 Hello friends I have a 4ft sump which i found out yesterday that is way undersized if the pump stops. i have a glass sheet in the tank reducing the sump down to about 3ft. my question is can i remove that glass with out the pressure blowing the tank out? here is a pic, i am wanting to take out the glass on the right.

raycam01_au Posted August 17, 2009 Share Posted August 17, 2009 Hiya Buddy Easy as, remove it cut it in half and use it as a baffle then u can add media and or more sponge etc where your pump is now and use the smaller section you have created for your pump. This is what i would do iffen i was you, but im not you but i would still do it if i was you, do you not what i mean!!!! hahahahahahahaa god i ramble craPe sometimes.. But do it Link to comment Share on other sites More sharing options...
Robbo2232 Posted August 17, 2009 Author Share Posted August 17, 2009 That was the first plan, but I would have to shut the sump down, drain it and let the silicone dry wich would kill all the bacteria So at the moment I would like to cut it out. But I am worried that there wouldn't be enough strenght to hold the walls together Link to comment Share on other sites More sharing options...

But I am worried that there wouldn't be enough strenght to hold the walls together hi i think you will be ok to do it if its a 3ft as you still have the divider in place for your media chamber .. but if your worried then when you remove the divider that you want you can use it to brace the top of the tank..that way you dont have to shut down the sump Link to comment Share on other sites More sharing options...
Momo Posted August 21, 2009 Share Posted August 21, 2009 drill a hole or two through it? still have the strength, could be done very quickly, no messy cutting and re-silicone. Link to comment Share on other sites More sharing options...
Robbo2232 Posted August 22, 2009 Author Share Posted August 22, 2009 Drilling isn't a good idea as i want to use the glass later on, if i can this weekend is it!! i am going to cut it out, unless any one is going to warn me other wise. Link to comment Share on other sites More sharing options...
Momo Posted August 22, 2009 Share Posted August 22, 2009 i think it looks like it provides some good support, why not cut out, cut 2 inches off the bottom and silicon back in? Link to comment Share on other sites More sharing options...
Robbo2232 Posted August 22, 2009 Author Share Posted August 22, 2009 would it be ok while the silicone drys, its in use at the moment so it would have to be above the water line, i suppose that a bit of masking tape would hold it all in place.

Momo Posted August 22, 2009 Share Posted August 22, 2009 i dont think it will be a problem with silicon drying. i've heard silicon can actually dry underwater (could someone in the know confirm?) not sure if it is toxic to fish though. i personally feel any brace is a good brace how wide is the tank?

Robbo2232 Posted August 22, 2009 Author Share Posted August 22, 2009 it 4ft long 2ft deep and 18" high but it would only be half full when the pump is not running Link to comment Share on other sites More sharing options...
TALLNEV Posted August 22, 2009 Share Posted August 22, 2009 do you have any spare glass? you could just glue another piece in the section without water then once it has cure pull the existing piece out. Link to comment Share on other sites More sharing options...

Robbo2232 Posted August 22, 2009 Author Share Posted August 22, 2009 thanks Jason, When can i pick it up? lol Link to comment Share on other sites More sharing options...
genetik_defekt Posted August 23, 2009 Share Posted August 23, 2009 silicone is apparently toxic to fish untill cured as it relseases acidic gases. this is why they tell you to "wait untill fully cured, then rinse thoroughly before adding fish" on the tube. i have no idea why that glass is there. Who made/designed the sump? is it a actual 4ft tank thats been converted? as i dont see any top or euro style braces it may be not a good idea to take it out as yet.

Robbo2232 Posted August 23, 2009 Author Share Posted August 23, 2009 Thanks Yippe I have been told it was a plant tank in a shop, there was another glass divider in there next to the pump on the right hand side i removed, you still can see the silicone there. I didn't think it would be OK to remove another sheet. there was originally 4 sheets of glass in there that were lower than the tank allowing water to spill over and keeping the plants separated.

Colfish Posted August 23, 2009 Share Posted August 23, 2009 would it be ok while the silicone drys, its in use at the moment so it would have to be above the water line, i suppose that a bit of masking tape would hold it all in place. just remove half of the existing panel, put extra filter material in that chamber and put the pump in the next chamber. no silicone involved, filter still operational, no mess job done.

Robbo2232 Posted August 23, 2009 Author Share Posted August 23, 2009 but still would be a mess behind the tube is a PVC pipe that's glued in, can i still cut it half way and remove the bottom piece? I suppose there would be no leverage to get it out or to crack the glass. Link to comment Share on other sites More sharing options...
rosco Posted August 28, 2009 Share Posted August 28, 2009 This is not a bad situation to be in. I would add another piece or two in the dry section (in whatever config you like, i.e half the height or whatever), and then remove the one that is there. All you would have to do is drain the sump and cut out the piece and refill from the tanks above. If you are worried about your own silicone work,you could test fill the chambers before you do all that. Just use aquarium safe structural silicone like V10. cheers rosco Link to comment Share on other sites More sharing options...
