Submersible return pump? ~2k gph?

[Hellion179]

Found my sump has a crack in the back. It is not the best designed and currently has two return pumps.

I'm thinking about pulling it out and replacing it with a 55g aquarium. I'm not up to drilling glass right now, so I'm interested to see if anyone has a pump suggestion that I can drop in there?

My current setup has 2x external pumps that create a combined gph over 2k. The display is 150g, so that seems a bit excessive. I have plenty of flow from powerheads.

Doh, didn't see that this was submersible.

Anyone running a Jebao DCT8000 in sump? It's a lot better than what I'm running now wattage wise.

Thank you.

Have you looked into the Ecotech Vectras? If not, i recommend reading up on those.

Those are some gorgeous pumps, but single income and the cost of a masters program....I don't have that kind of money right now. Looking for a short term fix, I have a year left of school.

Completely understandable. My next recommendation would be a Sicce Syncra pump. The 5.0 does approx 1300gph. I run this pump on my personal tank, as well as the smaller fish systems at my store and I love them. Extremely quiet and reliable. The company offers a 5 year warranty as well. The only issues I have experienced was from a customer who's calcium levels were way high. This caused buildup on the magnet of the impeller, thus causing it to burn up after only ~3mo of it being in her tank.

My only concern is that the flow rate is low compared to what I'm running now. I'm not sure how the tank would respond with a much lower circulation. Can you think of any problems that could arise?

Thanks

depending on how large you make the return chamber, you can always run 2 pumps(also good for redundancy). If your tank has 2 overflows, it would be best to run 2 pumps rather than one. splitting the returns off of one pump will dramatically decrease head pressure, aside from what you already lose with return height and the distance the water has to travel

Fluval SPs get good reviews.

I recently picked up one of the new Jebao DCS 9000. It does 1300 - 2300+gph. It's low wattage and fairly high head. The flow curve on it is pretty good.

It's too early to tell how reliable it will be.

I have the sp4. Killer pump. Go with the sp6.

Eheim and Mag pumps are also easy to find used. Mag 18 would give you 1800gph.
