Getting The Best From Your Aqua One AquaStart 340 Pro Trickle Filter.

The Aqua One AquaStart 340 Pro’s overhead filter is one of the tank’s largest advantages. It is far larger than any internal filter could be and takes up almost zero space inside the tank. The filter’s flow through compartments mean that a great range of mechanical, biological and chemical filter media can be accommodated leading to superb water quality if the filter media are correctly maintained.

We suggest the following as the best maintenance regime for your Aqua One Aqua Start 340 Pro Trickle filter:


Check visually to make sure that the filter is flowing well and that the intake strainer isn’t blocked with debris. Check also that the green 69S foam isnt blocked.

Four to Six weekly

Clean the filter out, rinsing the first stage Green 69s foam thoroughly in some aquarium water which is then thrown away. Clean the Bio Noodles the same way. The twin 69c Carbon and Polymer Wool cartridges should be replaced as they cannot be rinsed and their performance is essential to the health of the set up.   Have some Bio Noodles or BioRing Plus on hand and exchange a few pieces for new ones to keep your filter media fresh and the bacteria culture lively.

Six monthly

Exchange the 69s Green foam block for a new one as these become much more blockage prone over time. Don’t change the foam and the BioNoodles together. As too many ‘good’ bacteria are lost all at once.


Fit a new 69i impeller to maintain performance. Check all pipework and connections for leaks. Consider a new intake strainer if yours is very caked up and crusty.  Half an hour spent now means a whole year’s worth of trouble free performance from your 340 pro.
