New tank, pump & water amount question

[WallyTime7]

Hi there! First post and new to the hobby.
Just started to cycle last night on my RSR 250. I have a Ecotech Marine Vectra S2 going at about 40% and keep dialing the drain valve right, yet to find that noise sweet spot. Couple questions:
1) Is 40% on my pump sufficient? Specs are 1400 gph max and my tank specs call for ~600
2) What level do you have your pump chamber of water? I'm trying to keep it 2 cm above the pump exit so it's still water sealed
3) If I keep turning right on the valve to raise my overflow chamber, do I need to adjust my pump %?

I would say that flow rate is fine. I have a reef octopus varios 2 maxed out and i think that pushes closer to 800gph. Which now thinking i could probably dial it back but its working out nevertheless...
The level in me return chamber is about 8 inches and the rest of my sump sits at around 9 inches. I kept this high for noise and a little extra water volume
No you do not need to adjust your pump output speed. You dont want your water speeding through your filtration. Its okay to have the pump push at a slower rate. Allows time for your filtration to do its job.

Welcome. here are my thoughts on ur questions;
2) I keep my return chamber several inches above pump. Just make sure to do a power outage test to ensure u don't have too much water in sump and it wont flood during power loss.
3) depends on flow rate. after each adjustment, I'd check tank and sump water levels often for several hrs to ensure its balanced and that any adjustments are being handled by pipes/pump. whatever you do, you don't want too slow overflow or water will start overflowing over the tank glass bc drain cannot keep up.

Can you put an anti siphon set up on this tank? Fool proof on power outage.

Absolutely, u can install a union check valve near the return pump. Make sure to follow direction n install it correctly, vertical preferably. But many folks will not recommend adding a check valve bc it’ll fail one day. U can also drill a small hole at the return portion in the display, this will help break siphon during power outage

Mine has my tube that returns to the sump from the tank almost to the top, and is a slde fitting that is adjustable with u at the top with a debris screen. At the top of the U there is a small hole that acts like a vent. It is set up to be only a short distance below the top of the water level in the overflow. If the power goes out about 2 gallons drains into the sump, and stops. It does not even come close to overflowing the sump
