Is it wise to try to redrill a tank to accommodate bigger bulk heads? I have 1 .25" drains and 3/4" returns. I want to use a Reeflo Dart for all of my equipment. Should I try to redrill for 1.5" drain and 1" return to maximize GPH or should I just convert them to 1.5" and 1" respectively by using couplings said:
I have a 210 gallon that I am setting up. Suggestions are highly accepted. said:Great.. for a tank that size you'd want no more than 1100 gph return for the tank itself. 3-5x is typically what I recommend, though I like a little more personally, so 1100. That Dart would be way too much IMO. 3600 is A LOT of flowYou are just putting water in the tank, not generating flow inside with it, rely on your powerheads for that.
For the chiller, run it through on the return itself, not separately fed so from the sump, go into the chiller, then up into the tank. Figure you'd need an extra 200gph or so to get through that, that brings it up to 1400gph. Then you have your calcium reactor, depending on the size, 200-400 should be plenty you think? That brings it up to 1700. If you toss in a couple of two little fishy reactors, that adds on another 200 or so for 1900.
PanWorld 250PS is pretty powerful, so you shouldn't have ANY problems with equipment off it. Its 1" out, but you can back that down prior to entering your first piece of equipment, just don't choke it off at the pump itself.
I've got the 150 and it barely noticed my chiller.... Im going to be splitting it off to run my new 65G as well as my new refuge, so they have plenty of power.

Reeflo Marlin is also an alternative and has an output of 3/4 already.

Unless you setting up closed loop.. or have one or you think its going to take a ton of extra to get through the chiller, these sizes should be plenty for your application.
Hopefully someone who has done something similar can pipe up in case I am missing something.
I pouted for an hour or two then I called him and asked if he could redrill the tank and he said yes. He came a couple of days later and redrilled it. It went pretty smooth and came out great. My tank is only a aga 40b. So I don't know if he could redrill yours, but if you would like, I can give you his name and number. I'm sure if you explane what you need, he will be able to tell you if he can do it or not. He is really reasonable.Great info DaveJ. Marc has recommended a PanWorld pump but he was recommending one of the smaller ones. When I plumb for it said:The 200 or 250 is fine I should think.. the 150 is too small for your system in my opinion, that is what I have on mine. I just like to build in wiggle room
That is a good question.. I think jumping from 1" to 1.5" on the pump may help reduce head loss down the system.. so you go 1 right off the pump then 1.5 into the manifold then what ever size you need off that.
On the returns, go as big as you can as quickly as you can and run it straight into the sump. 1.5 would be plenty big.

I run a reeflo Dart with a 1" drain and 3/4" return just fine. That Dart can be throttled back and it will use less electricity when you do so. The extra power is there if and when you need it to run additional equipment without compromising the turnover rate of your tank. Between head loss and running additional flow through a reactor manifold, that 3600 GPH turns out quite a bit less.
My drain plumbing is 1.5", stepped up from the bulkhead down to the sump. My return plumbing is 1", stepped down at the bulkhead fitting.
Just to make sure I understand what you are saying on the drains I have a 1" bulkhead. The plumbing from the 1" bulkheads should be converted to 1.5" to the sump. From the pump go to the manifold with 1" or 1.5" then to the return with 3/4". You see I am totally confused. If the chiller is going to one return should I go off the manifold to the other return with 3/4" or 1"? Did you mean to say drains when you mentioned go as big as quickly as I can? said:
