No I honestly don't. I am now understanding more that all these things are quite important and won't be neglecting in the future. I only really concentrates on ph and ammonia. But more so ph. Just once I checked ph and it was low and I noticed he wasn't doing so well .. But that was changed and I've been on top of that but none of the others. Will do from now on. Never really thought of this guy to be needing such care! But he'll get it now that's for sure , I just need to get him all cleared up I'm afraid he won't last too much longer. I'll be getting one of this test kits tonight
