got a tetra tec last year set it up 1 of the valves broke of, managed to fix the problem myself. couple of months later cleaning it the propellor broke managed to fix it. cleaning it tonight the catch broke the valve broke again the house connector to the main unit broke seems to me its not so robust and i wasnt being heavy handed it just broke to bits. now my 200 liter tank has no filter running DO you reckon the media in the filter still with the tank water in it will be alright till 2morrow till i get a new one if not has anyone any suggestions
