just as title says... oh and side question.. can liverock 'live' in brackish?
Okay. Out of my depth here. I've never looked into fish-only Saltwater aquaria, as the live rock is such an excellent filter. So I'm not sure.steed1172 said:interesting...so if one was to set up a Saltwater without LR they wouldn't NEED a protein skimmer?....or would the filter media become "live media" and produce the same effect?
Cool info. That answers half of the issue. The other half being; why would a saltwater tank produce more organic bits than a freshwater tank? With the addition of live rock, it makes sense to me, but without, I just can't see what would cause that.funkman262 said:I'm pretty sure that any tank, whether freshwater, brackish or saltwater, will produce organics. But from what I understand, protein skimmers only work in saltwater tanks because the high salinity which also makes the water more dense allows for the surface tension that's needed in the bubbles in order for the large organics molecules to adsorb to them. This is an interesting topic and I hope some more people give their .02
The reason we need tiny bubbles is because they remain in water much longer than large bubbles which is important because the organics need time to adsorb to the bubbles. It's the same reason some protein skimmers are 6 feet tall.steed1172 said:but smaller bubbles usually are better due to smaller bubbles can be made faster, and each carry separate particles..
It's been a while since I looked into it, but I remember there are some strict rules to properly keeping a deep sand bed. Just like how freshwater tanks with sand require stirring so we may do it manually or just add some malaysian trumpet snails, the same is true for saltwater. There are certain organisms that are required in order to make it work.steed1172 said:DSB fualt being... pockets of harmful gasses? aswell as nitrogen pockets
Skimmers remove protine from water before it breaks down causing your ammonia, nitrite and nitrate to take a hit (caused from foods, fish waste, other decaying matter).steed1172 said:but the question really has been answered, it is not a necessity for a brackish setup, as it is usually for fully marine.
