Big Tank Flow Rate

[KNH]

If you install a drip system you can get away with less gph. I wouldn't get caught up on a certain number, so much depends on your stock and how often/much you feed.

Seriously tho...You've got a lot of good advice here.

To fine tune it any better we're going to need your stocking list w/sizes and your wish list if this isn't it .

Example:
If we're looking at sharks, they will appreciate some end to end current...rays just appreciate clean water.

I'm gonna & for a while, your in capable hands... Watch out for CHOMPERS he's smarter that his brother looks.

thanks guys for the replies.

I really want to just keep one tank and throw all my fish there, but I might still keep the 210 as second setup just in case..

setup 1 - 24" chilli red asian arowana, 1 - 17" motoro stingray, 1 - 20" tigrinus, 2 - adult blood parrots, 1 - adult green severum, 2 - 10" peacock bass, 2 - 9" ordinary pleacos

setup 2 - 10 asian arowanas (15"-21" in size)

If the bio-load is too much, I am willing to keep just the arowanas & plecos in the 1200 gals and the rest in my 210.

I have all the fish listed in 2 smaller setups right now.

this also puzzles me - I have 2 - 2" pipe running from the tank to the filter box, then 1 - 2" pipe running from the filter box to the pump back to the tank. When I open the gate valve feeding the pump all the way, the water level in the filter box goes much lower (may 10" lower than the aquarium) right where it enters the filter box, but level stay there, filter box never run out of water.

In my estimate, having twice the pipe (gravity fed) should be able to keep up with the pump.. .

also, I could see some air coming with the water being pumped back into the system, but I checked and double checked my plumbing, I cannot see any hole in the pipe running to the pump that's expose to air (above water level). The pump also makes some ticking noise, which I think is because of the air coming through.

what do you guys think

...I think that the 10x rule applies when you're using HOB filters. High turnover rate will increase mechanical filtration and do little else but waste power IME (if you have sufficient bacteria).

It will be helpfull if you post a picture of your equipment.

I recommend four to one. What is the input and output sizes of your pump ports?

Turn off your pump and look for water dripping from the plumbing. I would expect it to be at the valve handle or where the plumbing threads into the pump.

I turned off the pump a number of times, no leak at all. pump ports are 2" intake, 1.5" output
