Herbie drain plumbing

[R&J Reefs]

Anyone using 1.5 inch drain lines on Herbie type drain systems ???

Planning too on my 225 G new build. Still trying to figure out what to use for a strainer. Can only find up to 1”.

another question is do you need Ø1.5 drain lines?
A Ø1.5 Drain line running at full siphon will do in the neighborhood of 3700 GPH, compared to a Ø1.0 that will do about 1600 GPH

You know what return pump you will use so you need to decide

I use both 1" and 1 1/2" drain lines on my tank (three 1" siphons, though none of them at anywhere close to full capacity; then 1 1/2" for the two backups) ..... but it's 450 gallons. On more reasonably sized systems just 1" may suffice.
