Within the next 1 to 2 months the big tank should be completed. It is about 4,000 gallons. Come on guys, Im not some beginner that went out and bought all of these fish. The only two I payed for was the ripsaw cat and the albino oscar. The rest were rescued from people that had the fish in no bigger than 60 gallon tanks. They are going in the 700 in the next week once I get my titanium heaters in just to give them more room until the tank is ready. The 10,000 gph pump is running at about 5,000 gallons per hour, which is close to 17 turnovers within the hour. There is also an eheim professional 3 on the tank.
I often wonder what other people would if they got the call to rehome larger fish. Would they go out and get the larger set ups and make plans for huge set ups like the 700g and the 4000g you are doing. I am always amazed at how people like to talk down to those who rescue larger fish and wonder if those who naysay have tanks to equal the size of those who do the rehoming.
I decided the filtration was not enough on my 300 and I was not satisfied at all. I just got one of my big pumps in yesterday and decided to put it to use until my big tank needs it. Took me 4 actual hours to build the filter and I think it is pretty sweet. It is an absolute beast at moving water with that pump. It filled the 50 gallon trash can in about 12 sec before I toned it down and put drains to the tank. lol
I spent $250 on the pump, $80 on everything for filtration including trash can, and $150 on plumbing pipes.
so for about $500 I have a filter that can filter anything I throw at it. I already love it. It is not running at the moment because Im gonna let everything dry for a few days before I actually run it.
I still think the current set he has for all those fish is substandard, and "rescuing" all those fish when you don't have the space for them is pretty sick in my mind.
