Hi

I have been away for quite a while and haven't posted much but try to keep in touch when I can.

I know for many people, the thought of going through all of the water it takes to keep the discus going is a hard thing to swallow and if it is a concern to you and if you plan to have multiple tanks for many years to come, it may make some sense to look at putting in one of these:

Greywater systems are becoming more popular across the globe as they take water that is generally used once and then sent to the sewer system and instead, filters it and stores it where it can be used for flushing toilets and even irrigating lawns and gardens.

The upfront cost of a pre engineered system is not all that cheap, but it can replace its cost over time in water savings, is better for the environment, and can be done much cheaper if you decide to buy the components and do it yourself.
