No nothing to check the ppm but I do check the Ph. I've lowered the feed and am letting them use it up instead of just chucking it in. Reasonably pleased with no2 and hopefully no1 will recover. To be honest I learn best by trial and error.
Another thing that wasn't helping was no air circulation in the room other than a little desk fan. Cut through the wall yesterday and installed my fan and filter so the air is getting replaced every hour now, they were looking a bit livelier when I got in from work tonight.
