First off, this is my first tank so I'm obviously inexperienced with this kind of thing. However, I have spent quite some time looking all of this up so I'm fairly confidant it will work but I'd really like a 2nd (or 3rd ) opinion. Basically, I have already purchased myself all of the equipment needed for my tank and the tank itself. I got a 55gal tank and made sure to get a suitable filter (Penguin BIO-Wheel 330), lights, aeration, and heat. The thermometer is checking out at 78 degrees and the water has been dechlorinated and is at about 6.9-7 pH. It has been running like this for a few days and I have been adding BioZyme and small amounts of fish food to kickstart the cycling. At this point it seems like everything is OK, and I'm starting it out by putting Cherry Barbs in. That way, they won't immediately die if something is wrong and I can have some time to correct the problem, since they are supposedly very hardy fish. After a week with the barbs in, I was going to put more fish in - and continue with this until I get all of the fish I plan to add. Basically, I wanted several Angelfish but probably no more than 4, depending on the ones stocked at my local petshop. I was also considering a single Bala Shark, an Opaline Gourami, a Siamese Algae Eater, and some Clown Loach after a few months so I could be sure it would be well established and cycled. I was just wondering if there were any noticeable flaws in what I'm doing and whether or not I should change it at all. Thank you for your time!
