Tiger eye statement
How much time would you have available to spend on your tank per day. Remember, whatever you do today with a smile on your face due to it all being new, becomes a job in 3 months time, becomes a major schlep in 6 months time. For example an Algae Scrubber. They work marvellously. But they are a mission to clean every week, they drip water all aver. And you need to be able to install it so that you are able to get to it easily.
And how much monthly costs you are willing to spend on your tank maintenance. I'm excluding running costs like electricity. Talking about additives, dosing stuff, pellets / cubes top ups. ...
Cheapest to set up is a DSB, then Orca Cubes then NP-Pellets, then Vodka dosing and other Zeo-vit options...
simplicity to complexity, the same as with the cheapest to more costly
How involved. Basically the same. Once a DSB is setup correctly, it needs no attention.
Effectiveness, That is in reversed. Zeo-vit systems looks fantastic. Where DSB systems can struggle to maintain 0 phosphates. Orca cubes is more effective than a DSB. And they work quicker.
Not a simple choice - hey...
