other than simple green, anyone have a product to recommend that keeps regrowth down?

funny, I have exactly the same issue, and my vinyl siding is sort of green...

Mine cleaned off fine with a house wash mix designed for use with my pressure washer. Coat it with the wash solution and pressure wash it off. Came off easily.

Our vinyl siding installers recommended Spray 9. [www.spraynine.com]

I've used it on small sections successfully, but I haven't the energy to do the whole house. A couple of years ago we hired a local company to do the house the right way. It was $350 as I recall, but they did a nice job and I didn't have to think about it until...well, now.

cleaning it, NP. Pressure washer does a great job. But I'm looking for something to prevent it's regrowth every 6 months.

we looked at that. Does it keep the algae from growing back, at least a little?

Tried the wet and forget on our vinyl siding. We couldn’t tell if it keeps the crud away since it didn’t do all that well removing it in the first place. Not much effort for not much effect.

I just hit it with a bleach solution (1 qt bleach to 3 qts water), cleaned it off and nothing grew back for about a year.

Growing older is mandatory. Growing up is optional.

I got my house cleaned "professionally" about six or seven years ago, and it stayed algae free for about 4 years. But it's come back just the same. Since it cost about $700 to do it, I am definitely looking to now do it myself (it's not the whole house, anyway but just the northern sides). Closely following.

The red-rimmed melania, scientific name Melanoides tuberculata


Malaysian Trumpet Snail
This particular species of snail is practically required for any planted aquarium.

malaysian trumpet snail for eating algae and removing from aquariumThese snails are prized for their tendency to scavenge for food underneath aquarium substrate. They are detrivores and will eat plant and protein matter found underneath the substrate while also coming out to eat soft algae.

Their drive to look for food underneath the substrate effectively makes them plow the soil, so to speak, aerating it for live plants. The only drawback is that this species of snail will very quickly and rapidly breed within the aquarium if food is abundant.
