Lim Wave Series I pump
its the 1/15hp version. This guys pumps are ultra quiet and ultra energy efficient. Pulls less than 150 watts each.
Lim Wave UV
- the 40W version
Changed my sump plan to a multi filter sock design too. Will get the sump fabricated this weekend. I have all the acrylic and welding solvent here and ready to go.
this is fail safe. The main siphon should never back up. If the filter bags clog the water level will rise until it overflows into filter pad section. If filter pads clog the water level will rise until it overflows into the main pick up chamber and bypass all filters.
It has 2 emergency drains that can each handle full pump load individually.
This is called a "BeanAnimal" standpipe system from the guys over at reefcentral.
System should never have to be shut down for cleaning since the filter bags will pull out from the top while water is flowing down through them.
You should be okay with the sump design.
The 5% or less side will not cause much issue.
the wet/dry section make sure to have it sealed ...particularly for where the top enters that free fall and tower section. I would suggest having the Dry tower section right where the water comes in but higher than the sump overall, then from there.....have the water fall genetly into the filter bags.
Then post chem media bags/sponge filters(more biomedia) at 30ppi 4" blocks from Swisstropicals.
It's hard to get around the filter bags and the wet/dry tower iissue without loosing gas. One guy used a separate pump and sent the water to a wet/dry sealed tower. You can sponge filter the snot out of the water and then run a post Nu Clear or Large canister pleated filter after the same section if you want that micron filtration.
Then have the wet/dry at the 1st stage, then sponge/chem media, then the heater/CO2 etc...then the post cartridge micron filter.
They make some nicer larger ones for bigger tanks also than nu clear etc.
I'm less inclined to use those LED's.
3 W crees spread out over the entire spread is better IME and most reef folks deal with these issues also.
