I've covered all places were the light was hitting water I'm also planning on moving pumps outside ov room I've also got fan pointing at pumps. I can also add another two way air pump. I can keep my room temp at 22 easily wich keeps rez between 18 + 20. Is the room temp ok. Also the silicon was in a clear bottle and iv had it a year so I chucked it and got new one I also changed rez. Also is there anything u need me to take photos ov. And am I right in thinking not to use flash when taking photos of roots. It's hard to do one handed
