Redone 350 Gallon tank, another gravel swap

I like the style of this tank! this is a very large display. great job!

 

Tom, this tank looks just surreal!!...Dutch and Nature combo kinda sorta-ish...Love it...Is the tank 30" deep?. Do you get in or just scape on a ladder?.

 

whats the name of the fish on the fifth picture with black line and half red line above it? i been trying to finde out but no luck?
thanks

 

What kinda rocks are in this tank? Any ideas how I can get my hands on something like that (in Iowa)?

 

Where can one find Flourite Black. Not much luck on net. Looked on Seachem's site and it is not listed?

 

Great, thanks Tom.

 

Received the Flourite Black today

Very small size compared to Flourite red?

Looking at Tom pics FB has bigger granules, see pic

Edit: after getting the Flourite Black in the tank it looks very similar to Tom's. Small particles went down, large particles stay on top.

 

Hi Tom,

The tank looks great! Wonderful job! Any recent pics?

A couple of practical questions if I may:

1. How did you remove the old substrate?

I just use a big square wide net and scoop a net at a time. This allows water to drain and captures a lot of the crud as well, but is pretty sloooooowwww. Plus, the tank gets real dirty quickly due to the cloud of dust/mud that is released and I have to stop frequently until it clears.

This then goes into the heavy duty doubled trash bags, but is pretty labor intensive.

Is there an easier or better/quicker way?

2. How much rinsing did the flourite black require? Was it very dusty, or not too bad? How does it compare to the red in this regard?

Thanks.

 

Hi Gerry,

If you don't mind I'll tell you what I did.

First moved fish to small temporary tank. Then used 1" diameter hose to suck out old substrate. This drained into 5 gal bucket with a discharge pump hanging near the top of the bucket. This allowed the substrate to be deposited in the bottom while the dirty water was pumped out to the lawn. This does use a bit more water but makes quick work of the substrate change.

I did prerinse the Flourite Black and it was worth it. After filling the tank it was nearly clear. My other option which I used on another tank was to not prerinse and run a diatom to clear. This worked well also.

 

Hi Chris,

Thanks for sharing. Exactly what I wanted.

1. I thought of that, but didn't know what to do with the water that came with it. I didn't want to do a bunch of little buckets as they would fill up quickly.

I have some 40gal strong rubbermaid containers I use to move the tank when I relocate every 3-4 years. I can pump the substrate into this and place a small rio inside to pump the water to the drain. This should work fairly quickly. I still have probably 100 lbs of gravel still in the tank.

Great idea! I will leave the fish in the tank, though, as I am doing 1/3 per week..........

2. I figured I would rinse at least a bit, but wanted to know if it rinses easily or takes a long time per bucket, so I can set my expectations

Thanks again for all of your help.

BTW, my flourite has not come in yet, so last night and just now I removed the top 1" of old stuff as it was nasty with slime and brush algae.

I then did a couple of 70% WC and while refilling, gently vacummed the remaining subsrate. This allowed me to clean a lot of the sediment that gets stirred up.....Will make the replace go a little cleaner

Looks better already. I will vacuum more later as it settles again, and replant until the new substrate arrives.

Gives me a chance to play with the design, even though I do have a plan that I would like to try first.

Am off to find some more plants, as not all I wanted got shipped.......

Later and thanks again!

 

In regards to the grain size of the Flourite black.

I have always thought Flourite Gravel was too big, so I tried Flourite Black Sand and found it to be way too fine. It seems more like dust than sand and the result with my crypts has been generally poor compared to other substrates. I would have preferred something on the order of the size of Onyx Sand. The picture of the "Black Gravel" you posted above seems about right to me, so I'm going to try it. Of course I now have 100lbs of the sand I don't want. Ugh!

Recent Pics/question?

Hi Tom,

Two questions please:

1. Any recent pics?

2. Did you have any algae or other issues or a mini-cycle since you did this?

I have some brown algae/diatoms now that I have replaced the entire substrate over the last 3 weeks. Showed up about 3-4 days after the last 50% was replaced.

Am doing every other day 50% WC with prime and EI dosing with NORMAL Excel dosing (not sure why folks go over that???) and seems to be going away, but a bit early to tell.

Fish are fine and plants are doing well, just look brown.....

Thanks again for all of your help...
