flow in my troph tank

[mgarrido]

cool!

[geoff_tropheus]

Personally, in a 4ft 75 gallon I would go with (2) Aqua Clear 110's.

I am not a huge fan of making the tank a whirlpool of flow. I think the key is 7-10X turnover with canister/HOB filtration, or 5X with a wetdry

I would use your tidepool wetdry with a MAG that is capable of 600gph. The Mag7 at a height of 5 ft will flow 420gph. You will need a overflow box capable of about 500gph. The cost of the mag pump is about $100 and about $100 for an overflow box.

If you are planning on keeping the Eheim 2217, then I would definately get another Eheim 2217 or bigger if budget allows, and then keep your 300gph powerhead. This option will run you about $150 for a new 2217.

I still think the (2) Aqua Clear 110's is the best. You can probably find these for about $70 a piece online, or used ones here for $30-40 depending on age.

I would not put more than 15 Adult Tropheus in a 75 gallon aquarium. 18 max.

Juvinile 3" and under you could go with about 25 but understand that they will need 6ft aquarium or 120/140 4ft to house them properly.

My opinion that is a lot of lighting for a 75 gallon, you could go with much less, but that is a really nice fixture.

I sent you a PM on the fry.

Tropheus are very addicting man. Be careful...

[TaTeR ToT]

i no, i love them!
i had both my 75g filled withtrophs petros.

i had 19 dub maswa f1's, and 1x petro. trew.
and then in the other 75g i had 17 moliro's, and a moshi.
i love them, but just fell in love with sa's for a few years, i want to try my hand again though.
i have a second 2217 lined up.
and i am getting a k3 ph.
so should this be enough?

[geoff_tropheus]

plenty

[fshfrk]

1 k3.

[fshfrk]

Hey tater if you keep them for 6 months I will buy you a brand new K3. Ya'll are his witnesses

[myjohnson]

Vortech

sorry, had to beat Thai to it...

You got me Donald! I was off the forum last night.

but yeah, + one on the mp40w. You can turn it down was low as you want and as high as 3,000gph. Should work with fry, adults, and an upgrade to a bigger tank if that happens later.

battery back up to save your fish when the lights are out.

Value does not go down much. If you can get it for 325 brand new, then you can sell it at that same price if you don't want it no more 2 years later.

Or just plant a vortech tree. They produce powerheads at a decent rate. )

[myjohnson]

Where you find it for $325? That's a great price.

One fills a 4ft tank very well.

Or add more flow via filtration (ie wet/dry)

I just got another one for my 125g. And yes you where right. One just don't do it on a 6 footer.

The tree keeps bearing fruits.

Might get another for the 4 footer but I think the tree is done for this season.

, hey John you got any K3's for me?

I agree with most of what geoff says. You can have all that and things will be fine.

Back in the day, I had just two HOB. One was rated for 400gph and the other 350gph. No power heads, no canisters, and no wet/dry. No problems either.

But I later changed my prospective and it's not about the minimum. It's about take care of the fish. It's about providing for them.

So I buy things that I think will make my tank closer to lake conditions.

To each his own. No rule is written in stone except two!

1) water change
2) feed them the right food

Does this apply just to Brian or can I use the deal too?

Thai, what do you consider lake condition?

(2) Aqua Clear 110's on a 75 gallon is not minimalistic or neglecting the fishes, one bit. That is 13X FILTRATION turnover, not just water movement. Just because someone did not spend a fortune on powerheads and filtration does not mean they are neglecting these fishes.

I agree. I was referring to my two old HOB that I had on my 75g.

That is 13X FILTRATION turnover, not just water movement. Just because someone did not spend a fortune on powerheads and filtration does not mean they are neglecting these fishes.

Again, I agree. Example, a modded tunze nano stream (which I have) or a modded MJ (which I had) moves water just like a vortech.

Like I stated above. I agree with what you wrote. If Brian set up his tank just like you recommended he would be fine. He might even be fine with less. Not providing lake conditions does not mean neglect.

I do think that providing extra filtration, extra water movement, and integrating safety back-ups allows for the fish keeper a little more margin of error.

[Mzungu]

I'm still curious what you meant by "lake conditions." Elaborate? Thanks! :)

[myjohnson]

Brian,

Here is a link you might fine helpful, assuming you already don't have it.

"By having your water constantly moving, you increase the surface area of your tank. The layer in contact with the air is always changing and consequently you dramatically increase the rate at which oxygen can be dissolved into the water, and carbon dioxide is released from the water. The surface area of your tank is always the limiting factor in the number of fishes you can keep in a tank. So, by artificially increasing your tank’s surface area, your tank is then able to house more fish."

"we should pay attention to water movement is because moving water carries oxygen to the denitrifying bacteria in your tank’s substrate. It’s these bacteria that are responsible for the breakdown of harmful waste products (i.e., ammonia and nitrite). Their breaking down ammonia puts it into a form that allows your plants to use it (i.e., nitrate).

And most harmful bacteria are anaerobic. That means that they thrive best in conditions with little to no oxygen. So, by providing a greater air to water interface, you increase the concentration of oxygen in your water, which both your fish and denitrifying bacteria need, and harmful bacteria dislike. "

Decent read. It'll help you decide for yourself how much flow you want. If you are set on getting 2xk2s then google modded tunze nano stream, you might save some money if you got one PH and it provides about the same amount of flow as the 2xk2s with less use of electricity.
