I've decided to go with pea gravel too. It took about 5 times to wash the mud off the lava rock, I think I lost about half the lava rock . I went today and bought some pea gravel at the concrete company ..... 50 cents for a 5 gallon bucket .... I got 5 buckets full, virtually no washing needed since it's been snowed on all winter, and it looked washed already. I think a little sand will be better than lava dist sediment
