Introducing the new Turbo Algae Scrubber! (Rev 4)

got you both!

 

Actually I'm not sure that is the right stuff. Everything I've read says the ABS to PVC solvent cement is green. But I'll add this to the list of things to check into, thanks @rapidjohn

 

I've got you down @jfowler!

 

@Todd Leatherman I'll put you down on the L8 list and PM you about your L4

 

^^ that's the stuff!

 

Yes, with some things taken into account. Over a sump or tank drain plumbing can be friction-fit. Remote-mounted, you may want to solvent join the plumbing where it is not over a tank. The drains are not under a lot of pressure like they would be from a pump, but they are not under negative pressure either, unless you don't have a drain valve in place (which would cause a sucking/gurgling sound.

That being said, friction fit plumbing will very likely keep everything sealed up pretty well, you might just get a bit of salt creep. If you supported the pipes correctly and used TFE paste (teflon) on the joints and pushed them together well, you would minimize this issue. Or, if you needed things to be sealed well but not "permanent", bond a union to the drains (but it'll be a 2" one!!)

 

@dwayne that depends on a few factors such as what other filtration you are going to be using, but in general, the L2 should be enough for the 90g unless it's really heavily stocked and fed. As for the 300/450, that's definitely in the L4 range (that's where tank turnover rate comes into play) unless you have a lot of co-filtration or some other "primary" type of filtration, like biopellets + big skimmer, etc - then you might be able to use the L2 as a supplementary or complimentary level of filtration. If you are going for a more "primary" scrubber-based filtration system, then the L4 and maybe the L8 if you want it to be the workhorse of the system.

 

Well I'm pretty sure the L8 will be less than twice as much as 2x L4's, but I have no numbers to crunch really. When injection mold dies get bigger, cost goes way up. So I may have to get creative with the parts
