First of all I use wet/dry filtration on both of my tanks. I love them, they are great.IMO
As for that tank. I was actually looking at the exact same tank.
I am planning on making it a reef tank. The thing about that tank is it comes with a built in wet/dry. However with it being built in, it is harder to maintain and it tanks up more room than an acrylic with a built in overflow. It is a 50 gal
but in all actuality it is really more like a 45 gal
because of the built in filter.
I use crushed coral and aragonite substrate.
Do you mean fish to put in the tank? If so, I too have 2 kids and they also love watching the fish. I happen to love triggerfish. Since you have a puffer, the trigger would make a good tankmate for the puffer but not for the clown. I have kept 3 different puffers together and they did fine, so if you want a porcupine, I say get one, however, I would suggest a bigger tank. Some people will suggest a huge tank, but I will suggest a 75 gal
for your puffer and a porcupine puffer.
Since you want something with easy maintenace, I would not go with the tank I mentioned above. I don't know how much acrylic tanks are in your area but a 75 gal
with a built in overflow (not wet/dry) with blue backing runs about $315 and a decent wet/dry runs about $250 but you may beable to find a better price. You will probably be able to find a better deal on the internet, but the price I paid together is a little more than the tank you mentioned. So you will probably be able to get that around the price of that tank with the built in wet/dry.
By the way when you buy an acrylic tank with a built in overflow it comes with all the hook ups for the wet/dry filter. The wet/dry will go below your tank for easy access for maintance.
As for the algae on acrylic. My green algae comes off rather well. note: there is special pads you use on the acrylic to scrape off the algae without scratching the tank.
Yes water changes are thingsyou will have to due no matter what kind of filter you have.
Hope this didn't confuse you I kinda got on a rambling streak, but I hope this helps
