Ishak Custom Aquariums

It depends on the tank size, the amount of plants and hardscape, and the equipment you choose. For most beginners, a complete setup (without fish) runs around $500 for a 9–20 gallon tank that's both practical and beautiful. Smaller setups can start as low as $250, while large or high-end builds with CO2 systems and dense planting can go significantly higher. In general, more plants and more advanced equipment means a higher price — but it also means a more stunning, lower-maintenance result.

A lot less than most people expect. For a heavily planted tank — which is nearly every tank we build — all you need is a 25–30% water change every two weeks and daily feeding. That's it. Use a siphon to remove the water, add conditioner to fresh tap water, and pour it back in. Tanks with CO2 or heavy fish loads may need a bit more attention, but for the vast majority of setups, it's very manageable.

Yes — but you must add water conditioner first. Most water utilities in California use chloramine to disinfect tap water, and chloramine is highly toxic to fish and the beneficial bacteria that keep your tank healthy. Water conditioner neutralizes chloramine and removes heavy metals, making the water safe. Just add the recommended dose to your tap water before putting it in the tank.

This comes down to the nitrogen cycle — your tank needs a stable colony of beneficial bacteria to convert harmful ammonia (from fish waste) into less toxic nitrate. Naturally, this takes about two months. However, we typically recommend bacteria-boosting products that can cut that wait down to about one week. There's a small added cost, but it saves a lot of time with the same end result.

Easier than you'd think. Our recommended method is having a friend or neighbor stop by once a week to feed your fish — just pre-portion the food so they know exactly how much to add. If that's not an option, a quality auto-feeder works too, though the reliable brands can be pricey. Water changes aren't necessary unless you'll be gone for several months. The one thing to avoid: dumping a large amount of food in the tank before you leave. That will spike ammonia levels and can stress or kill your fish.

Live plants do a lot more than just look good — they're one of the best things you can add to any tank. They act as a natural filter, absorbing ammonia, nitrites, and nitrates that would otherwise build up and harm your fish. They also produce oxygen during the day, which keeps your water healthier and your fish more active. Plants give fish and invertebrates natural hiding spots, which reduces stress and encourages more natural behavior. They also help outcompete algae for nutrients and light, meaning a well-planted tank tends to stay cleaner with less effort. On top of all that, a tank full of live plants simply looks more alive — there's a depth and movement to it that artificial decorations can't replicate.

Algae isn't inherently harmful — it actually absorbs ammonia, nitrites, and nitrates just like your plants, and it can be a food source for certain fish and invertebrates. That said, it can outcompete plants for light and nutrients, and most people don't love the look. The best ways to deal with it are: turning off the lights for a few days to starve it, scrubbing it off manually, or — our favorite — letting cleanup crew animals handle it for you (snails, certain shrimp, or algae-eating fish).
