I am most interested in substrates just like you. I guess you can say besides fish, im a soil and bug guy. Lol. Going to be a science teacher in a year or so.
I boiled all the wood i am going to use today. Tomorrow i am breaking down my reef tank and taking everything to the live fish store for credit. I hope that i will have enough time tomorrow to go by the hardware store to get some egg crate, miracle grow organic and lava rocks. I have plenty of zip ties.
I think i will be able to modify the phosphate reactor into a co2 reactor. Think i could run carbon in the reactor as well? I think i can rig it up where the pump will pull it in, or i can put a line on the intake.
Ill post more pics as i get things done tomorrow. Thanks for joining in the conversation!
