water cycling question

Hi all, nice board. I am new here and I have a few questions about my tank. I have a 46 Bowfront with 60 lbs of lr, I have a dwarf lion, a juvenile sailfin tang, and a clown fish, along with some nassarius snails, a couple hermit crabs, and an emerald crab. My tank has been up and running for almost 6 mos. and here is my problem. about 2-2 1/2 mos ago I had a powerhead die, and my water movement was poor afterwards, it was like this about a month, and as a result, I got red slime algea. I talked to my lfs, and bought maracyn(freshwater) to solve the problem. I used 4 total tablets, and everything was fine except my skimmer went crazy, i eventually got it working right again, but I am afraid between all the water changes i made to get the maracyn out, and the fact that the maracyn is an antibiotic, it has disrupted my bacteria bed and my tank is recycling. my ammonia had always been 0 til about 2 weeks ago, and has been climbing ever since, it was off the charts yesterday, and I unfortunately don't have anywhere to take the fish to keep while the tank recycles. I have done water changes almost daily trying to dilute the ammonia, and yesterday I added amquel+, it seems to have brought the ammo down a good bit, but will it interfere with my cycle? nothing has died yet, the fish seem kind of sluggish, the snails and crabs appear fine, wondering how or if i can get through this with as little loss of life as possible. any help would be appreciated, thanks.

PS: at least the red slime is gonelol

Thanks for the quick reply, i appreciate it. I will continue with the water changes, is 5 gals a day good? or more? also, with the tang, I am looking to upgrade to a bigger tank, I'm thinking a 125 would look great where the 46 is(hope my wife thinks so too). as for the nitrites, they were at .25 sat, then at 0 sunday morning before anything was added, then I added the amquel because the ammonia test was basically off the charts, the amquel i added is amquel+ so it says it rids the tank of nitrites and nitrates also, so the nitrates are at 0 as of now.

wanted to thank you for your help and give you an update. after battling the ammonia problem for a couple weeks and watching it get really out of control, i decided to give bio spira a try, i did a 50% water change to get rid of the amquel i had been using, after the water change the ammo was around 4ppm, nitrites were 0, i tested the ammo the next morning, and it stayed the same, and nitrites were already present in small amounts. it took about 48 hours to really kick in bringing the ammo to near 0, and the nitrites peaked at about .50 i added it thursday, and by monday morning the ammo was 0, nitrites were 0, and the nitrates were kinda high at between 20 and 40. all in all i felt the stuff worked as advertised, and i accomplished what i wanted in getting through this tank re-cycling with no fish loss. also, i guess i learned why a sewer smells the way it does, must be the bacteria, because that is exactly how bio spira smelled to me
