So I rid my tank of the hydra shortly after posting the picture by using a tiny piece of de-worming pills for dogs from petco lol. The substrate was ADA if I remember correctly. My CO2 tank ran out over 3 months ago and I never decided to get it replaced, after taking down my salt water tank I was depressed about my tanks and just let it go... Topping it off with sink water and watching the algae go crazy. I finally about a month ago decided to do a nice water change with RO water and now top it off regularly after my cat drinks from it lol. This is what it looks like now with almost no help from me/ no CO2/ no chemicals. It's also completely algae free and I dropped a beta in :]
wow, it looks really good! I've been having a ton of algae issues too since getting a new high-light fixture. It's helped to reduce the photoperiod to just 7 hrs, but then I like to see the fish. I'm seriously considering going back to my medium-light desk top lamp, and seeing that hc is growing fine for you, I'm REALLY tempted to give up the aquasky!
