Welcome to AquariumAdvice.com!!!
I would like a reef aquarium, but I want a less expensive alternative to a wet-dry filter. Is that possble to obtain?
You can use a "Berlin" method for filtration. It consists of LS
and aggressive skimming. Wet/drys, when maintained properly will not cause an increase in NO3
. They do take some work however.
What would the absolute minimum size tank be? I currently own a 10 gallon with freshwater, but I doubt it'll be enough.
You can attempt to keep whatever size tank you want. That said, the alrger the better, especially for beginners. The larger the tank volume the more stable the water parameters will be. I would recommend something larger then a 10 gal
, a 29 is a great place to start. Keep in mind that the bioload on SW
tanks needs to be much less then FW
tanks, so you would be very limited in the number and types of fish you could have in a 10 gal
(or 29 for that matter). Many people start out with small tanks only to find themselves wanting something bigger in a few short months. You will out grow a 10 gal
very quickly. At least a 29 w or 38 gal
would give you more options.
What types of fish would you recommend?
This really depends on the size of tank you end up with. If you are interested in having a reef tank then limit your fish to ones that are reef-safe.
Go out and get yourself a copy of "The Conscientious Marine Aquarist" by Robert Fenner as your next step. It is a great resource and will help you in getting started.
