Hello all. This is my first post on this forum. So I would like to introduce myself to everyone. I just recently was able to get back into the hobby. I have moved around for work quite a bit so keeping tanks become difficult. When I moved from Ohio to Northern Kentucky for work i lost all my tanks unfortunately. So for the past two a half years I have been waiting for the right tank and deal. I would not settle for anything less than 180g. Since moving to the Tampa this past November all i had been able to find were 125g. Luckily this past week after years of searching i found a great deal on the 180g i currently have sitting in my living room empty. I am really trying to plan everything out on this tank before I do anything. I have not yet even decided on the fish I will be keeping. I do know however it will be a planted tank. I have had a planted tank in the past but they were not as well thought out. I am a member on MFK, under the same user name. I wanted everyones suggestions on the substrate to utilize. I am thinking of doing a hill or a bank in the aquarium. I was thinking of doing 2 inches of fluorite with a sand top layer. My other option would be to do all three inches in fluorite. I want a carpet look in some areas of the tank. So I wanted everyone opinion on what works best in your opinions. Also I wanted everyone's opinions on substrate heaters. Are they work it? I thank you all in advance for your assistance.
