1. Do I need mechanical filtration to go with the Bak Pak?
I currently do not use any mechanical filtration on my sw
tanks. Even with feeding, there is very little particulate matter in the water column and what does exist seems quite natural to me.
2. Will the longnose hawkfish and damsel get along? Hawkfish spend all their time at the bottom of the tank. Are they in any danger from the starfish?
I would think they should be o.k
. As far as the starfish, the green brittle star is one of the few that are actual fish predators and should be steered away from.
I've read that hawkfish eat a variety of marine meats, but will they also eat pellets? If not, what can I put in my Eheim auto feeder to feed them when I'm on vacation?
Never had one, but....how long are you going on vacation? It is likely that if it is only for a week or so your fish will be fine without feeding if they won't take a dry food.
4. I've read that starfish are good tank cleaners, but how much do they eat? Is the uneaten food at the bottom of the tank enough?
In addition to what it scavenges, I direct feed my banded serpent twice a week or so a meaty food like shrimp or squid.
5. Does Instant Ocean also raise my tap water to a pH of 8.2, or is it just salt?
IO will mix normally to the proper PH and also contains a list of trace elements, etc in addition to salt.
The only thing I don't see is what you might use for a substrate? My suggestion would be to create a Deep Sand Bed (DSB
) to help with nitrate control and to reduce the amount of maintenance required (over say, crushed coral). DSB
