I am going to be doing the BeanAnimal style overflow for my new setup. It is a 40G Breeder with a 28G NRS-30 sump. The head height will be around 35ish inches + or - a few. I really only have 2 questions. First would 3/4" PVC work or should I go with 1" to be safe? I feel like 1" might be too much flow for the setup. Second what size return pump should I get? Im thinking an Eheim Compact 3000 would do the trick or do yall think it wouldnt be strong enough?
