Scott's 270g aka Project Mayhem

It has begun! Damn is my RODI slow! I have the 100psi booster on there and it's still painfully slow.





Return plumbing is 90% done. I just have to paint the 90's black and glue them in!

nice accessible sump off to the side. i loved that about my fish room too. i had always planned to add the fridge but you beat me to it lol. looks great!

Great job on the plumbing, did that silicone hose come with the pump?

Thanks Steve. I had to order the silicone connector kit from Abyzz. The clamps are pretty badass though!

man, you kids and your fancy schmancy fish rooms. So jelly right now!!

I like putting heaters in overflow boxes, good amount of turnaround and wasted space otherwise. You'd probably want at least one in the bottom sump as well though, if you drain it for water changes or maintenance you'll probably want to preheat the water before turning it back on, unless you have a heated storage bin for that.

Locline returns!

I am hoping to have a ~40g mixing tank that will have a pump and heater. The profilux will run that pump with a sensor to perform water changes.

A couple kinks to still work out there for sure. Sounds like that pump sure pushes a lot of water, I know when I ran the two wavelines I had to cut out the weir teeth to handle the flow properly, but at the time concept was cutting pretty narrow teeth. You can add risers in the overflow but they shouldn't prevent the the tank from draining to overflow weir height, only prevent the overflow box from draining and control the overflow box water level to prevent trickling noise. If the teeth is holding back that much water they may be too restrictive. Basically you should try and limit the tank to 1" water level drop during shut down. Usually 2" is actually my go by number but with large tanks and small sumps that's not usually possible. With 1" you need space for 3456 cubic inches in the sump which means if the sump is 48" x 16" you need 4.5" of extra space above running water level. Now if you're seeing a 2" that's 9.5" in the sump needed which isn't going to happen.

I don't see a check valve on the return, that's potentially a way of reducing some back flow if it's draining lower than weir height, if not then not worth while.

The problem with the baffle is it really shouldn't be a baffle to be honest, one of those things that got lost in translation, not shown on drawing. I'm use to building these myself out of acrylic so most of the time all the details aren't shown. The baffle should be more of a screen, just to protect the pump, like mine:

The freezer is awesome! All the fish food is on it's own and I'm not leaving the little foil squares from the PE Mysis in the people food freezer. I am looking forward to working on the tank once it's up and running. I am still being cautious not to crowd equipment in and still don't have everything 100% figured out as to where I want it. For example, I have 3 x 300w EJ heaters that I don't know where I am going to put. Sure they can fit in plenty of places but where is the best lol!?
