how do i get my boring sponge to grow? I want some encrusting stuff on my rocks like filter feeders and sponges and corraline and i have bits and peices of them but i want them to be more invasive. i didnt really have any blooms of stuff besides dino in my tank which i basically erradicated, i had some chaeto/sea lettuce kinda bloom for like. afew days then it stopped growing. how do i trigger new growth in my tank, im using plant fertilizer from my fresh tank in hopes that it gives my macros and stuff more nutrients to grow more. also i wanna know how long it will take for my gsp to recover, it has algae on part of it and idk if i will hurt it if i scrub it every day while it grows in and gets natural immunity to the algae, also i think i might have some dead gsp polyps, i tested my water last night and i had 0 am 0 nitrite 15 nitrate 0.25 salinity. would adding tap water to my ato for the silicates be a bad idea, i know it fuels sponge growth
