questions on adjusting gh and kh

I've been running my tanks very soft--gh 5-7, kh around 3, but have 1 tank I'd like to run hard enough to keep brichardi. I've removed all the old fish prior to adjusting the tank for the new ones.

How rapid an adjustment can the plants take? Can I adjust it all at once, or do I need to do it over a period of days or weeks?

I'm also wondering if I'll have any surprises in store in terms of how the tank uses nutrients, produces algae,etc.

I used a list of brackish adaptable plants to decide what to put in the tank. I figured if it could handle brackish it could take hard, alkaline water. If there's an error in my thinking, please let me know.

Thanks,

I don't think you'll have a problem adjusting it all at once as long as there's no fish in there. There are very few plants that won't grow in hard water. But if you're talking brackish as in sodium then you might have some problems with certain plants.

Your water is fine for keeping the Brichardi..or most any plant.I keep one in my 55g w/gh:7/ kh:3 ph:6.8 to 7ish
I've had him for almost 2 years, his tank mates consist of rams, angels, rainbow sharks, festivums, a few tetra and platy, he even has teeth...
Dug him a hole under one of the logs in the tank. thats his spot...

Thanks Marcel. That's what I needed to know. I'm not using brackish, I just figured anything that could handle that could take hard, alkaline water.

Brichardi, for those who aren't familiar with them, are a Lake Tanganyika cichlid and have an interesting reproductive pattern. A pair will claim a small patch of rock for a territory, and while not really agressive towards other fish, will drive other fish from their turf. The first spawn is usually pretty small, but when the fry mature, they aren't driven off. Instead they stay and help raise/guard larger, subsequent spawns. The parents will move out a little to expand the territory. With each batch, the parents expand the territory, the larger siblings move outward guarding an inner rim, and the youngest stay with the eggs.

They're not a flashy fish, but they are somewhat elegant in appearance. They're an old favorite of mine and I've missed having them around the last few years. Since I've added some tanks back to my collection, it was time to bring some back home. Also, they're a lot easier on plants than many cichlids.

That's the fish Craig! They're my favorite African cichlid.
