Hello everyone,

I am a total noob when it comes to planted tanks. I have had a couple of smaller (10 and 20 gallon) tanks that I have mainly kept guppies and mollies in, as well as basic plants (no fake stuff for me, thank you very much!). However, for my 30th birthday recenly, my family all chipped in and bought me a monster 75 gallon tank.

Here's how it looked when I first received it:



(You can see my original post with tons of pics here)

(And pics of my adapting the filter to the existing overflow filter and sprayline here)

At first, I was intrigued by the idea of setting up an el natural tank, and even bought some cheap topsoil to try it out. As one person suggested, I tried to demineralize it beforehand by soaking it in two tubs of water; it smelled like sh*t frankly, and the mud was as black as midnight. "There's no WAY I'm doing that to my new baby!" I thought. So I abandoned that idea and bought some Flourite instead. Here's a couple of pics of that setup:

Gravel border going in:



Flourite going down:



Gravel on top:



... And cheap-o PetsMart plants to kick off the cycling:



So today I finally went down to my LFS (Neptune's Reef in Torrance, CA) and bought some driftwood and my first round of plants. Additionally, I switched out the 50/50 white/blue 10,000K bulbs with some all-white 6700Ks (there are 2 x 55W). I realize that for such a large volume tank this is definitely on the low end of WPG. Any suggestions? Just suck it up and buy a new ballast and bulbs?

Here's what it will look like with the driftwood, once it's been properly soaked to leach out the color:



Here's the first round of planting, after removing the driftwood again so it can soak separately.



I will be adding some gravel to the back to slope it some, after reading some more posts here on APC :D Also, I might add a layer of Aquasoil (that's the medium-smaller grain, black soil, right?) over everything ... yes I realize I'll have the "Grand Canyon" layering effect around the edges ... I kind of think that might look cool. My wife is going to flip however - she loves the look and color of the gravel I have in there now.

I have a little Hagen yeast-based CO2 system going right now, just to add SOME CO2, but plan on replacing the miniscule Hagen container with a juice bottle setup that should produce much more gas. I am currently dosing every other day or so with Flourish (the regular kind). Is this about right? Oh and I'm going the tapwater route - 75 gal. is too big to mess with lifting giant 5 gallon jugs of RO water to shoulder height, not to mention purchasing and schlepping all that water from the LFS.

Please can anyone help me here - again, I apologize for the noob questions - I see this stuff that people refer to as "HC carpet" or an "HC bed" - it looks like that beautiful ground covering, very tiny leaves. What is that called, where can I find some, and how does one plant and grow it? Do you have to have Aquasoil to do that?

Many thanks - stay tuned in the following weeks as I add to this page. :mrgreen:

Re: New 75 gal tank journal

hey Mark the tanks looking good. Just a word of caution those plants on the right the green white ones are not exactly aquatic plants. The grass out there in the front also looks like mondo grass which is not aquatic. it will start rotting in a few day.

Hey Houston!

You know, those are indeed two of the Petco plants - they are from Top Fin (sorry this is a bad pic):

Re: New 75 gal tank journal

Added my first two new residents: a pair of sailfin mollies:



I also added a little powerhead to disperse the natural CO2 a bit better, and to create some movement at the bottom of the tank especially.

The driftwood is soaking along nicely :) I am glad that I am doing it in the sink ... it's already turned two sinkloads of water a little yellow/brownish.

Re: New 75 gal tank journal

HC is Hemianthus callitrichoides. You'll definitely need more light if you want to grow it. You can get it in the For Sale or Trade Forum just post that you're looking for it. It will grow in fluorite and is not terribly demanding; but you would need more light than you currently have.

Hey thanks Nevermore. I was wondering what that lovely HC was, and if it could grow in Flourite and gravel (the gravel shouldn't hurt, right?).

I have examined my lighting hood and am considering my options. If I want to maintain the integrated hood look, I think I have a couple of options (I'll post up some pics of the lighting part of the hood soon). I can either buy a new, higher-wattage ballast (to replace the 55W x 2) or try to cut and drill out some of the hood (there's room alongside the current bulbs) and add some more WPG that way. I haven't really decided yet. It would be great to NOT have to heavily modify the hood already, but I kind of have to wonder what the manufacturer was thinking when they designed and shipped a 75 gallon tank with only 2 55 watt bulbs/ballast (I guess they were thinking along saltwater lines, but I think 1.47 WPG is a bit low even for a reef setup).

Someone suggested that I could try 65W bulbs with my 55W ballast ... I dunno. I'm all about not burning my apartment down. I think I'd rather suck it up and DIY the hood into holding another fixture or two.

Re: New 75 gal tank journal

I've added a couple of dwarf puffers just for fun:



And here's a recent pic, pre-trimming:



Some algae starting to come in. I have a shipment of plants due to arrive soon as well ... might have to move some plants around before their root systems take off much further to accomodate the new stuff.

Re: New 75 gal tank journal

Puffers will attack another fishs,i've lost 11 cardinal tetra cuz of them.
I've heard this about full-size puffers. Does this also apply to the dwarf variety?

So far, they only go after each other. They leave the sailfin mollies alone ... but I do want to get cardinals, will this be a problem with the dwarf puffers I wonder?

Re: New 75 gal tank journal

Holy crap, I am going to have to find another place for these guys! It sounds like my guppy tanks are out of the question...

I've been pondering having a tank at the office. I keep wanting to do it, but am afraid that the bossman will make a stink about having 5 or 10 gallons in the cubicle next to the computer. :mrgreen: I think I'll do it anyway, and keep the puffers in there.

That's a great idea! So you can watch those puffers chase each other at work :D . May I suggest, if you are using c02, make sure surface agitation is kept to a minimum to reduce c02 loss. Tank looks good, but i'd refrain from getting petsmart plants, especially the ones in the tube. The one's in the their plant tank is ok but only if it's fresh because for some reason they always end up rotting and dying until a new shipment comes in. If your real serious, I believe it's worth to buy plants online like from www.aquaspotworld.com or www.azgardens.com :)

Re: New 75 gal tank journal

Since you just bought the puffers, you might check out the Dwarf Puffer thread on the "fish for the planted aquarium" board. Lots of discussion there from people who have been successful keeping DP's in a community tank and people who have not - including how to tell the difference between males and females. (The females are less aggressive and easier to keep with other fish.) It would be worth a look.

Thanks for the tip, Shannon.

You know, I have done quite a bit of reading on the dwarf puffers since I got them, and indeed it seems that of the two surviving ones, one is a male and one female. The male is hyper-aggressive toward the female. I will probably move him first when I set up my office aquarium (probably a 3 or 5 gal cube/nano - shh ... don't tell my wife! ;) )

Hello MrHarris,

Just a quick update - the Petsmart plants are 100% removed from my aquarium. NONE of them did well and to hell with them ... they're toast.

With respect to your surface agitation comment, I fully concur and in fact (upon reading Diana Walstad's book) I have removed the spraybar from the filter return, so that it just comes out into the overflow filter in one big stream:



My rationale is that this will help prevent some of the CO2 loss due to the uber-agitation that the spraybar inherently produces. *fingers crossed*

Re: New 75 gal tank journal

sepparate the male, and hopefully the female will settle down and be a good tank citizen, if not you can either return her to the pet store or another tank. these guys dont seem to mind being alone and actually seem to do better at least IME. i've been lucky though and so far all my dp's are not agressive to any other tank critters except the scuds that infest all of my tanks, which is a good thing. i keep them with shrimps and tetras and no problems. each one seems to have its own temperment and personality so you may just have to keep trading them back to the lfs until you get a docile one. good luck, i love the little buggers.
