Oh, I wasn't suggesting that you decorate your tank the same as mine, just illustrating a point.
And I was talking about American prices, I didn't notice you were from CA
What cichlids are you planning to keep? If you want African cichlids they will do better with aragonite/crushed coral like you are talking about because they need the higher pH. If you want South or Central Americans, it won't be necessary to alter pH.
If you really want to buy the kit I would advise you to add another filter in addition to the Penguin 350B. Cichlids are messy fish and 350 gph
may not be enough for them. I filter 680 gph
on my 55 gallon SA/CA
cichlid tank and it works great for me. Of course, if you can afford a canister, that would be even better.
