I know I am jumping in late here, lol, but figured why not?
I used to run aquaclears on my smaller tanks and they did very well for me. I ran carbon every other month, the sponge that comes with it and chemipure elite. The chemioure is good for several months too but isnt rechargeable as far as I know. It has gfo
in it which can help curb phosphates and in turn algae growth.
You seem to have a great start, you got a lot of great advice from the others.
For hanging my lights i used the store bought hang brackets from current, but they were $90! They do the job perfectly and since I can't figure out much diy it fit the bill for me.
A warning on those leds'. they are extremely extremely bright. I burned every single coral I had with them and never got the hang of them to be honest. lol I ended up going back to t5's on the one tank. If you do get corals just know to acclimate them to the light and start at like the lowest setting and work your way up. you most likely will never have them above 50% for each channel just so you know.
Good luck! I will continue to follow along.
