Weighing down Wedding Cake Steps ?

[matt4x4]

I've been trying to devise a way to reduce algae growth inside these type of steps.
Water circulation is the key here, without it, it doesn't much matter what you do, you will still get algae growth.
So, here's the best I have come up with.

Add a second return directly behind the stairs, instead of an eyeball, fasten a length of appropriately sized hose into the fitting and feed this hose inside your stairs - either located at the top to point down or at the bottom to point up, if you are using solar heat, I would recommend pointing it up since heat rises, so the warmer water would have tendencies to rise therefore circulating well from bottom to top of steps.

Well so far our Biltmore steps (straight) have no algae build up - they have all those flow through openings. However, I do tend to pour a bit of bleach there at the one side and top of the steps each time I run the auto cleaner - the water flows in a clockwise direction around the pool so the bleach poured before the steps will flow through them, the top it splash I give it is for good measure I guess. I have a super soft headed brush sprayer I use on the steps anyway and it shoots water into the corners.

We weighted them with the sand filled bleach jugs. I was dissapointed to find out that the compartment that pops open in the front was not large enough to put another jug through though. We found out that another jug was needed to keep them down but had to use a wrapped concrete block instead. I think we will fill some pvc tubes with concrete and go that way.
