Gray water tank algal mat

I was draining my tanks and the gray water tank spewed brown jello-ish algal blobs. There was so much,of it, it clogged the outlet and I had to use my finger to tease it all out -eeuw!. I flushed the tank with lots of fresh water. My first thought was to add a slug of bleach, but I am trying to cut down on my toxic bleach habit. Would just leaving the plugs out and encouraging air flow in the empty (?) tank help, or is there a preferred way to deal with this?
thanks

I will second that eeuw. There are tablets available at RV centers for just such thing. Pop into a RV center and ask what they suggest, there is a pretty big selection out there. Bleach would be a last resort for sure.

Winterizing is not an issue here in the citrus belt of Southern California - our record low is 28 : ) .
Yes it is the gray water tank -the soapy residue from dish washing, etc, seems to have formed a primordial soup. Having spent 30 years working in biology labs -I know bleach would take it out, but its rough stuff. I'm trying to be environmentally friendly, so I'm hoping a combination of airing out the tank and an RV tank tablet will help. I am sooooooo happy we don't have black water tanks too!

 

So how long does rv solution last. Due to Work issues we did not camp last year and our plan for a 3 month adventure now that we are both retired has been halted due to Covid so this winter will be the 2nd year with out camping. Wondering if we should drain tanks and rewinterize, just add some fresh antifreeze or what?

 

We are in the exact same boat Retired December 31 and then, boom! But, we’re going out in October for 10 nights in various state parks. We’ll keep away from people and use the bathrooms sparingly and with precautions. Time’s a wastin’!
