Will my sump overflow?

I have a 20 gal sump for my 75 and do not have any bubble traps...have 3 compartments one for inlet from tank with skimmer.one for ref and one for return pump..no bubbles here...also I used adjustable loc-line for my return into the tank so I can tweak the depth of this line to get the most volume out of my sump

So you would suggest that I don't use bubble traps? I only want two compartments as this will be a BBT. I have a Deltect AP600, and from what I remember it doesn't really produce much bubbles, so maybe it's best I just go without the bubble traps?

Cheers
 
What does having a BB tank have to do with having a fuge or not? A fuge where you can grow macro for nutrient export is a good idea either way. With a small sump, there is not much room anyway. I would use a larger sump and put the skimmer in it. An AP600 will add very little heat to the water. It would not make any difference at all in sump or external.

You have a 36"x18" Display, so lets assume 35"x 17" in the stand to work with. I would use a 30 x 16" x whatever height you want sump. You could also use an efficient smaller internal return pump like an Eheim 1250 to save some room in the stand. It will add very little heat.

MY AP600 has an aquabee pump rated 38W, don't you think that adds a lot of heat, or it doesn't really do 38W as it's gravity fed?

I like your idea about the eheim 1250, as it's rated 28W. Where I live in Philippines ambient temperature has been 37 Celsius for the past 3 months. I have a TecoTR15, but my goal is to mimimise heat as you can understand. One more thing to add is my MH which I already have is 400W, which is another big heat issue.

I will purchase Koralia's also as they are energy efficient and emit very little heat.

Just didn't want to add a fuge because if a BB is setup properly, there is no way macro algae can grow. I had BB before, and couldn't grow chaeto at all, as phates and trates were minimal to say the least.

Sorry, it didn't work. If you can post it agin, that would be great ;)
 
I had an AP600. They use a lot less power than the rating. Mine measured 11W. 38W is if it is pumping H20 only. Also, that is a water cooled pump. The pump is cooled by the water being pumped through it. Very little if any heat is dissipated to the air. Put the skimmer in the sump. For the return, if you are going to have an external, there is no benefit by using a water cooled pump. Unless you use an air cooled external, you might as well use a submersible.

Dont know what to tell you about the fuge. My PO4 and NO3 are undetectable. I have no problem growing Chaeto. I've seen many BB systems with fuges. No big deal though. You dont have to use a fuge.

That's awesome! The skimmer problem is solved, it will be in the sump. I'll just use that rio14HF, it's brand new and will give it a try. It will be outside for sure, as it's rated 45W.
 
Good news on the fuge sjm817. BTW, does it matter how small my return pump is? The eheim 1250 is rated 1200LPH whereas the rio14hf is rated 3500L.

Cheers
 
Rio's get very bad reviews around here. Many people have had them go bad and kill everything in the tank. Again, that Rio is a water cooled pump. It will add heat to the water whether it is in or out of the sump. You dont need a lot of return flow. General rule is 3 - 5x display size, 150 - 250 GPH in your case. The Eheim 1250 would be right in that range after head loss.
 
So it's pretty pointless putting it out of the sump? hehe. Thanks for the rule. I'll try it out.

My drain line is 1" (about 600gph), I just want to make sure if having a return 3x - 5x my display will not flood my sump.

How do you know if a pump is water cooled pump?

All submersible pumps are water cooled. With the externals, its a little harder. Most are air cooled, but not all. The Poseidon/velocity externals are water cooled.
 
Ok, so if all submersible pumps are water cooled, does that mean that it's pointless to have them outside? Will they really emit less heat when not in water?

I'm now thinking of a 24x16x16 sump, which will be 25gals. I don't want to go longer as it's saved for other equipment.
 
That is debatable. My thought is it makes little if any difference. The pump has no real water to air heat exchange mechanism. Its cooled by the water pumping though it either way.
 
Thanks. Debatable is exactly what I thought, but you do raise a good point.

So ok, I guess if I go with 24x16x16, I should have two compartments. 1st is the skimmer, and last for the return. Is one baffle enough? I was thinking of no bubble traps and just having one 8" baffle.

Also how many inches should I have the skimmer compartment and the return compartment, provided the sump is 24" long?
 
How big is your skimmer? That'll decide how big you need to make your skimmer section. Some skimmers are tiny, others are huge for the same performance level.

How about 15gal sump, 18x12x16?

Definitely 15g is better than 10g and if you can keep it no more than 2/3 full, then you have enough for an overflow situation. To play it safe, you need a minimum of 5.0-5.5 gallons for when the power interrupts. With the 15 gallon sump, if it was only 2/3 full at the max, you have at least 5g buffer. If only 1/2 full, then you have 7.5g buffer. Hope it is apparent why 10g is cutting it too close.

Just catching up on your thread. Looks like the AP600 will fit perfectly in your sump and should NOT transfer much heat back into the water since sjm says it only runs at 11w. I would partition a section that just fits your skimmer and if on the output you decide to go with a filter sock, you probably can do without any multiple baffles. Just have one for the skimmer section and one before the pump section and in between the 2 baffles is your fuge.
 
Thanks Klam, it really does sound like it's not worth putting the skimmer outside. I may just go with my return outside to play it safe. I only want two compartments, skimmer - return as I will not run a fuge, as I will go BB. Tried running a fuge before with macro and nothing grew on my old BB setup.

The filter socks works wonders for all systems, esp BB as it catches all the crap, so will just do with 1 baffle.
