I hate to steer this thread off the road, but i have a question about fish...
Ok, I have 2 very large goldfish (about 12in and 7 in). I change the water once a week, but all of the extra food and stuff settles to the bottom in the rocks. I bought some new gravel, and plants from petco, and was wondering if i could change all of that while the fish are in the tank? And, how do i clean the bottom of the tank when gravel is in there? Is there some sort of water vacuum or something? Help would be appreciated. I dont wanna kill em.

You clean your gravel with that,
Bouzouki, I disagree with your statement about nitrates and Cichlids. Nitrates will affect freshwater inverts just the same as marine inverts and will cause algae just the same. Nitrates are plant food, no way around it. Some Cichlids have specific pH and alkalinity needs that other fish don't like. I'm not a big freshwater guy, so to come up with a list of beginner fish would be too difficult. Salt is another matter. Having both fresh and marine tanks at home and at work, I don't think marine tanks are any more difficult than fresh.
I never said Nitrates wont effect Inverts, he never said anything about inverts, only fish.
They wont effect his fish in anyway.
Yes, it will cause algae to grow but that is if your nitrates are very high,
THe point i'm trying to make is, in a salt water reef tanks, everything has to read zero, in freshwater, it doesn't matter if you have low nitrate readings, he wont have to worry about them nearly as much.
In saltwater FOWLR tanks, people use Wet drys, Canister filters, etc, these are Nitrate factories, they use them because 1. they brake down Amonia and Nitrite, and 2. because even though they can't brake down nitrate, it wont effect their fish anyways.
In Reef tanks, you run no canaster filters, no HOB filters, nothing that traps debris, all you really need is live rock which is the natual way of braking down nitrates and a skimmer.
PH should be around 7.2 for Chicalds, I may be wrong, its been a while since I did fresh.
You may be able to compare freshwater and FOWLR saltwater but when it comes to reef tanks, there is no comparision.
Try maintaining all of these.
