I just wanted to put this out there for people to be warned ...Our mini bow 7 has developed a small leak , which will progressivly get worse , when I spoke to our pet store that use to carry them they stated that this is why they quit , for me to get another will require a trip but the worse part is is that AGA will not replace it or work with us , there warranty on the bow front tanks is marginal at best , so when you maintince your tank check ALL seams for leaks , we have not ever moved it with h20 so we dont know why the leak , for now I will patch it with a silicone sealer and if that doesnt work duck tape till I find a new MB7 tank to put in in place of it and test it for leaks as of now I am holding my breath that it doesnt get too much worse .........as it stands now I may not replace with a mb7 but something else I am not sure as to which way I may have to go wow what a head ache ..... so every one with an AGA tank check your seals especially a bow front ...
