I was browsing the pictures section and noticed the substrates in fenders tank and gayles tank. I thought they were fairly large gravel like mine. Fenders tank looks a lot like my 75 gallon. My question is have your tanks been running in that configuration for a long time? Do you use substrate heating? Is it neccesary? Do you vacuum or just perform water changes? I personally have not vacuumed in 6 months but I perform a 20 percent water change every 2 weeks or so. I've been monitoring my nitrates regularly and have found that they have not risen. In fact the nitrates fall to 0 and I must add nitrogen to the substrate regularly to keep the nitrate levels around 10. I've been using jobes plant food spikes for large indoor plants with a fertilizer profile of 14-3-7. I didn't come up with the idea, I saw it on another planted tank site. Its been working well for 1 month now. So far no algae and the plants are doing great. I am careful to monitor nitrates at least once a week until I get a feel of how much nitrate the plants consume.

Yes I do use fairly large gravel on top but underneath I have flourite which is really small. I have had this set up for about oh probably 7 months.

I do not vacuum the gravel ever. Everything in their the plants use for them self so there is no need. i currently do a weekly 10-15% water change.

Just be careful with the spikes. If you disturb your gravel and the spike is allowed to be exposed to the water you will have some algae problems. Believe me I know from experience :sad::fire:

It was not a happy time!
