Hi, first of all im not sure if ive posted in the right section so appologies if im in the wrong forum. Ok so i have a juwel 400 tank with one of those built in filters, now from keeping a few different species of fish in my tank ive come to the conclusion that the built in filter, well, it just isnt up to the task, so ive decided to buy an external filter. This leaves the problem of the filter that is stuck to the side pane of glass with silicone. Id like to remove this filter but im afraid that if i start sticking things inbetween the filter and glass im gonna have a shattering experience!! This must be avoided at all costs, so i was wondering if there is anyone who has had the same problem and has removed the built in filter, and if so, how did u remove it without breaking the glass? If anyone has any ideas or sugestions id be glad to hear them. Thank for reading and i look forward to your help
