pH and African Cichlids+ Stocking Tank

[paulW]

Wouldn't 50 lbs of rock be too little for a 125 gallon tank?I've been researching and it seems that demasoni are only aggressive with each other so that the solution is usually to stock a large shoal of them to even out the aggression so that one fish doesn't end up being the one facing the bulk of the others' ire. I have seen other people's tanks with both demasoni and yellow labs so I'm pretty sure it can be done. What species do you have in your tank alexmuw? Any other suggestions guys?

I had a demasoni that killed about 8 other fish (non-demasoni) before I figured out what was going on.. Some people have good luck with them, but some Demasoni are definitely phsycotic.

Can someone answer my question about floor space and weight? Namely this is whether I should be worried that a 125 gallon tank replete with water, 250 lbs of rock, fish and sand/crushed coral would be properly supported by my floor. It would be disastrous if it ended up collapsing into the basement! Is 250 lbs of rock a good measure for a 125 gallon tank?

Hopefully the demasoni I get will be well behaved.

I apologize for bumping my thread up again but I would really appreciate an answer. Also, How much crushed coral should I add to the 125 gallon tank if my current pH is 7.6? Would 20 lbs be a decent amount(mixed with regular sand)?

its not chemistry here, however much you add is good, considering your ph is already fairly high. 20 pounds will bring you up at least .2 which is darn near close to 8 and when kept consistent will have no adverse effects on your fish. Personally, if I was you, I'd go for Haps or Peacocks, just personal preference, but then you can keep all males to avoid hybridization and get the full color spectrum of all your fish. I'm just a Hap lover =]

As far as the weight goes on your floor, its hard for anyone to answer that with certainty.If I were to hazard a guess..I would say it would probably be fine. I have 125,75,55,(2) 30's, (2) 10's in one room on the second floor. Its been up there for at least 5 years.
If you live in syracuse, isnt there a stone quarry close by or some lake or river you can go stone hunting at? Thats part of the fun of setting up the tank and its free!

As far as the water parameters just keep up with water changes after you put your substrate in and cycle the tank, the fish will be fine. Most fish are acclimated to our water any way. Unless your ordering wild caught, I wouldn't worry about it at all.

cant really guess at how much weight your floor could hold without seeing the structure.Best to orient the tank perpindicular to the joists.
I added a joist and 2 uprights to support my floor when I had to sit the 125g parralel to the joists.$40 in lumber=peace of mind is a good deal!

As to adding more fish later,add groups not individual fish.Take out the rocks and rearrange them each time you add a group.
