Thought I would post this here aswell.. Has anyone noticed any difference in the bubble interation in freshater vs saltwater, due to the water density......

I get it ... can't respond so just delete my posts.. very mature.
The source of the white spots on the screen apparently has been found: A neon tetra knows how to get to the screen and hold his position in the rapid bubbles, while eating in one spot.
Am I missing something or are all of ACE25 's comments gone? I read this thread last night and now I don't see any of his posts. I wanted to go back through today and read everything with a clear head.
His phosphate posts are here...

Great :P after a long wait here it is at last...
since I am working on my own POC, I will give this design a test and see what gives. I came up with an idea for setting it in the sump...let me know what you think:
The idea is to hang the screen from a rod placed laterally on the sump's edge...have the airstone pump bubbles up the screen... still trying to figure out the lights though...how to have them on both sides of the screen....
my sump is divided into 3 sections:
1- water coming in from the tank then flows down into
2- main section -- usually to have skimmer & other gizmos
3- auto top off section...
so I guess the wall separating the "water-in" chamber from the main chamber can be made into a mirror and have the light at the side of the sump....ill draw it and post...
Here's the design with lighting.
what do you think?
I figured 2x the light would be needed because light will be reflected back onto the other side of the screen...but then its just guesswork on my part so I need input from the pros out there.
Ok just figured out something...
my original thought was that tying the screen would help in the cleaning process...just take the entire rod off along with the screen, scrub it and return...but I just figured I will need a way to keep screen in the air flow's path....maybe have the entire system to be removable? I mean secure screen to rod and airstone using zip ties or similar...just disconnect airstone from pump when need to wash and replace/reconnect when done...
I liked the epoxy idea proposed by Floyd to cover up all the sides of the stone thereby directing flow upwards only...would aquarium safe silicone be a good alternative? dunno about finding safe epoxy over here
so basically, to get back:
airstone sealed at 3 sides, leaving just the top side open to allow air out.
screen fastened to stone at the bottom and rod at the top.
rod rests on sumps edge...
since its all still on the theoretical side, im thinking if the first chamber will have enough of a water column to cover the screen up, since it will be the in-flow of water from the tank... maybe if i made the screen wider (40cm) with less height...SM would there be a difference impacting growth? I mean the intent is to have water covering the entire screen right? if water column is not too high, then i guess compensation would have to be done with the width to achieve desired surface area...
That what Doompie did. However the mirror will be blocked out in a few days.
OKK...you are right SM...Originally Posted by SantaMonica
sorry but its been nearly 36 hours up with practically no sleep (upgrading local operator 3G network and had some issues...)
since I dont want to play with immersed lights (esp the DIY part) I guess I'd have to look into something else...what about the angles used in your first post on this thread? is it any good? or maybe use two one-sided screens instead of one two sided...which is better you think?
