I was browsing and found this item and had some questions. It needs a pump I'm guessing, what one would be suitable? Does it work with a solenoid/PH controller? Do you have access to the other Pacific coast models? How about the Coralife model, will it work with a solenoid/controller? My 58 gallon doesn't need much, but I'm getting tired of dosing and something that will work hang on would be preferable. I don't have any room left in my sump. Anything else you would recomend? Thanks.
