Sharkey18 November 13, 2012 Share November 13, 2012 I am using 3 MP40's on my new tank and CAN NOT keep the dry sides from falling off using the pathetic attachments that are supplied. Anyone using something that works much better? Link to comment Share on other sites More sharing options...
Ryan S November 13, 2012 Share November 13, 2012 how thick is the tank laura? is it too thick for them to be used at all? are you using the plastic spacer? is it set to the correct tank width? Link to comment Share on other sites More sharing options...
epleeds November 13, 2012 Share November 13, 2012 I have Adam working on something for me but is there a reason why the wet side is falling off? Is the pin spacer in the correct spot Link to comment Share on other sites More sharing options...
Coral Hind November 13, 2012 Share November 13, 2012 If the pin spacer is set right and it's still falling off you could use zip ties and larger adhesive mounts to support the cord and hold up the dry side. http://www.securecableties.com/Mounts-Hangers/1-14-Inch-Black-Square-Adhesive-Tie-Mount-100-Pack-pID1018.aspx Link to comment Share on other sites More sharing options...
Sharkey18 November 13, 2012 Author Share November 13, 2012 It's 1/4 inch glass. The pin spacer is set correctly. I think it was the black Vinyl (?) backing. The adhesive mounts did not stick to it well. Once they fell off, the cord brought the whole thing down. The good news is that when they fell off, they severely ripped the black vinyl so I just tore it all off today. But of course, the adhesive mounts are now useless.... I think I'm going to crazy glue them to the glass.... Link to comment Share on other sites More sharing options...
Ryan S November 13, 2012 Share November 13, 2012 1/4" glass? that's it? mine is 1/2" and they stick fine. either the spacing isn't correct, or something else is wrong. at 1/4" they should hold very well. Link to comment Share on other sites More sharing options...
epleeds November 13, 2012 Share November 13, 2012 (edited) Your tank is at least 1/2 if not 5/8". 10 gallon tanks are 1/4". My new tank is 3/4" and I'm running them w/o the pin spacers. Edited November 13, 2012 by epleeds Link to comment Share on other sites More sharing options...
trott November 13, 2012 Share November 13, 2012 The wet side impeller nut is to tight, only finger tight and the white spacer should be flush with the base. Run your finger nail over it, should be smooth. Link to comment Share on other sites More sharing options...
OldReefer November 13, 2012 Share November 13, 2012 I tend to go one notch higher on the pin spacer than the actual glass thickness. They stay on better that way and I have not seen any bad effects. The little self adhesive pads are pitiful. Superglue or epoxy may be the best answer. Link to comment Share on other sites More sharing options...
zygote2k November 13, 2012 Share November 13, 2012 Your tank is probably 3/4" and if so, the pin spacer needs to be removed entirely to prevent the dry side from detaching. The little sticky things only work good if the surface that they stick to is completely free of salt. Link to comment Share on other sites More sharing options...
Sharkey18 November 13, 2012 Author Share November 13, 2012 Ah ha! Of course you are all correct. The tank is 1/2 inch thick glass. Now I feel like an idiot, but LOVE the fact that you can identify my mistake in an instant. PIn spacer adjustment to commence immediately. Link to comment Share on other sites More sharing options...

Steve175 November 21, 2012 Share November 21, 2012 In addition to making sure that the glass is clean/salt free, I think it is better to allow the adhesive on the adhesive mount to dry a full 24h before securing the power cord to it. I suspect that the bulk of your problem was the space [thank God your tank is not 1/4"!!!] Link to comment Share on other sites More sharing options...

Yeah, I can't imagine using 3 Vortechs in a tank made of thin, 1/4 inch glass. Try setting your pin spacer down more. I look at their setting as guidance, not absolutes. Like Bill said, set it for glass at least one setting thicker. Link to comment Share on other sites More sharing options...
