i was wondering how i should build a couple buckets into filters...i want to use these bucket filters for my 8'x3'x3' amazon setup... that im going to build soon which is somewhere around 540 gallons...the indoor pond will have a plywood platform where the filters will be visible and with easy access.I was thinking of have a strong powerhead to uplift water up into a connected tube lining to the bottom side of the bucket where it will be siliconed from the outside to the inside and have many bioballs and a polyfiber coating will be somewhere around near the top of the bucket where their will be another but larger opening with a pvc pipe running above the pond with a wider attachment to the end of the pvc pipe to let the running water out to the pond again...but the buckets lid will be securely on with some very heavy materials to keep an overflowing waters to get out of bucket from the top but if it does it will allow a stronger but beneficial* water flow out of the filter into the pond......What do you guys think of that idea...do you guys think their is a flaw in my idea? if so please point it out and we could all discuss it together and figure out what will be needed to be fixed to make sure its perfectly safe and constructive to work accordingly.
