Razor blade, vinegar and elbow grease.

Thanks, very much!

Pressure washer works good as well if you have access to one.

Do any of you in Edmonton remember the fishpond? was a home based buisness in highlands owned by a grumpy old guy named Jack. when i was new to aquariums I helped him clean a few he insisted on bleach to clean it.

I've used bleach before following the instructions on this site. It's just important to use the proper type, concentration, process and let it dry completely.

Yes, I DO remember Jack. That was so long ago! He WAS a grumpy old guy.

A 5% bleach solution would disinfect the tank. Rinse really, really well, then use generous amounts of Prime in the last rinse water to neutralize the remaining bleach.

Bleach won't clean up the tank, though. As already noted, vinegar, a razor blade and elbow grease will work wonders :)

Fill with water, add vinegear; 10-20% of total water volume should do.
add power head.

run for a day or two or three

From here, most algae with be gone and whats left will come off very easily with a razor.
